Initial Setup

The Platform will need to onboard it's business to the Zero Hash platform. They then need to add additional users, create API keys, and whitelist IP addresses. See instructions here.

1. Submit Payor

Once API keys are created and approved, the Platform can begin to integrate to the API. For the following examples, we’ll assume the Platform's platform code is PLAT01.

Payor Information

The Platform submits the Payor via POST /participants/entity/new

        "sanction_screening_timestamp":1677252628000
      }
    ]
}

You’ll receive a participant_code in the response - this is the Payor participant code that uniquely identifies the entity indefinitely. We’ll use PAYOR1 as the participant_code throughout the examples.

See response for expected shape.

The Platform must submit at least 1 beneficial_owners and 1 control_persons. If these persons do not have an SSN, the Platform must submit a document via POST /participants/entity/documents.

Payor Documents

Your Payor will not become approved unless you also supply the proper documents via POST /participants/entity/documents endpoint. Depending on the entity_type that was used in the original POST /participants/entity/new call, the document requirements vary. See details here.

The Platform submits the Payor documents via POST /participants/entity/documents:

{
    "document": "...", // base 64 encoded file that you wish to upload (10mb limit)
    "mime": "image/png",
    "document_type": "articles_of_incorporation",
    "file_name": "test.png",
    "participant_code": "PAYOR1"
}

State Logic

After a successful POST /participants/entity/new submission, the initial status of the entity will be submitted. In order to transition this to approved, the Platform must then submit all required documents, via POST /participants/entity/documents.

2. Query Payor

Platforms can query already-submitted Payors via the GET /participants endpoint. If you'd like to query a specific Payor use theparticipant_code parameter.

3. Fund Float Account

The Platform will fund their float account by sending fiat to the proper bank account. Here are the account details:

Participant_code: 00SCXM
Account_group: PLAT01
Account_label: general
Account_type: available
Asset: USD

ℹ️
In Cert, your platform will be pre-funded with Float account funds.

4. Submit Beneficiary

The Platform submits a Beneficiary via POST /participants/beneficiaries/new

Available to select Platforms only: you can conditionally submit either a phone_number or an email- you must submit at least one, otherwise the request will fail.

{
    "first_name": "Lucas",
    "last_name": "Martinez",
    "email": "[email protected]",
    "address_one": "Calle San Martín 305",
    "address_two": "305",
    "city": "Buenos Aires",
    "zip": "C1000",
    "jurisdiction_code": "AR-X",
    "citizenship_code": "AR",
    "date_of_birth": "1985-09-02",
    "id_number_type": "non_us_passport",
    "id_number": "A12345678",
    "employment_status": "part_time", 
    "industry": "consulting",  
    "source_of_funds": "salary", 
    "signed_agreements": [
    {
        "type": "payment_services_terms",
        "region": "us",
        "signed_timestamp": 1726005278070
    }
]
}

NOTE:

Even in Cert, Zero Hash will run each submitted Beneficiary through our Sanction Checks, subjecting the Beneficiaries to real validations. This means that if your entry is an actual sanctioned individual, the Beneficiary will be sent to a rejected status. Another way to test the rejected scenario is to enter an SSN of "111111111". If you'd like to test an approved scenario - ensure you as close-to-reality sample as possible.
Zero Hash requires that the jurisdiction_code is not null and contains both a Country (ie, Brazil "BR") and a Subdivision (ie, Sao Palo "SP") to form BR-SP, for example. If your systems don't contain the subdivision and you only collect Country and Postal Code, we recommend performing a mapping on your side to derive the correct Subdivision, using the Country and Postal code as inputs. See this step-by-step guide on how to use an external API (ie, Google Geocoding API) to make a conversion between your data structure, to ours.

POST /participants/beneficiaries/new response:

{
    "message": {
        "first_name": "Lucas",
        "last_name": "Martinez",
        "email": "[email protected]",
        "address_one": "Calle San Martín 305",
        "address_two": "305",
        "jurisdiction_code": "AR-X",
        "city": "Buenos Aires",
        "zip": "C1000",
        "date_of_birth": "1985-09-02",
        "id_number_type": "non_us_passport",
        "id_number": "A12345678",
        "metadata": {},
        "platform_code": "PLAT01",
        "participant_code": "BENEF1",
        "citizenship_code": "AR",
        "phone_number": "",
        "signed_agreements": [
            {
                "region": "us",
                "signed_timestamp": 1726005278,
                "type": "payment_services_terms"
            }
        ],
        "employment_status": "part_time",
        "industry": "consulting",
        "source_of_funds": "salary"
    }
}

You’ll receive a participant_code in the response - this is the Beneficiary participant code that uniquely identifies the natural person indefinitely. We’ll use BENEF1 as the participant_code throughout the examples.

Beneficiary State Logic

After a successful POST /participants/beneficiaries/new submission, the initial status of the Beneficiary will be submitted. At this point, Zero Hash is running an automated compliance screening. If the person passes this check, the status will transition to an approved state. If the compliance screening results in a hit, the status will transition to a pending_approval status. Note: there is also a scenario where the Beneficiary transitions directly into a rejected state, depending on the compliance score. Zero Hash’s compliance team will become alerted and will manually review the Beneficiary within 24 hours. If the determination after that review is that the Beneficiary should not have been flagged, the status will transition to approved. Otherwise, the status will transition to rejected.

Beneficiary Rejection Scenario

In Cert, if the Platform would like to test a rejection scenario, please submit a Beneficiary like the following, passing an id_number equal to 111111111:

{
    "first_name": "Lucas",
    "last_name": "Martinez",
    "email": "[email protected]",
    "address_one": "Calle San Martín 305",
    "address_two": "305",
    "city": "Buenos Aires",
    "zip": "C1000",
    "jurisdiction_code": "AR-X",
    "citizenship_code": "AR",
    "date_of_birth": "1985-09-02",
    "id_number_type": "ssn",
    "id_number": "111111111",
    "employment_status": "part_time", 
    "industry": "consulting",  
    "source_of_funds": "salary", 
    "signed_agreements": [
    {
        "type": "payment_services_terms",
        "region": "us",
        "signed_timestamp": 1726005278070
    }
]
}

Beneficiary Pending Approval Scenario

In Cert, if the Platform would like to test a rejection scenario, please submit a Beneficiary like the following, passing an first_name equal to Joseph and last_name equal to Kony

{
    "first_name": "Joseph",
    "last_name": "Kony",
    "email": "[email protected]",
    "address_one": "Calle San Martín 305",
    "address_two": "305",
    "city": "Buenos Aires",
    "zip": "C1000",
    "jurisdiction_code": "AR-X",
    "citizenship_code": "AR",
    "date_of_birth": "1985-09-02",
    "id_number_type": "non_us_passport",
    "id_number": "A12345678",
    "employment_status": "part_time", 
    "industry": "consulting",  
    "source_of_funds": "salary",

        "region": "us",
        "signed_timestamp": 1726005278070
    }
]
}

5. Query Beneficiary

Platforms can query already-submitted Beneficiaries via the GET /participants endpoint. A common query parameter is the participant_code, however the full list can be found on the API reference.

GET /participants/?participant_code=BENEF1 response:

{
    "message": [
        {
            "participant_code": "BENEF1",
            "participant_name": "Lucas Martinez",
            "email": "[email protected]",
            "status": "approved",
            "reason_code": null,
            "country": "Argentina",
            "state": "X",
            "jurisdiction_code": "AR-X",
            "updated_at": 1728607508503,
            "lifetime_remaining_limit": "0",
            "daily_remaining_limit": "0",
            "limit_currency": "USD",
            "limits": []
        }
    ],
    "page": 1,
    "page_size": 200,
    "total_pages": 1,
    "count": 1
}

6. Connect External Account

The Platform will connect the Beneficiary to an external account via POST /payments/external_accounts:

{
	"participant_code": "string",
	"type": "crypto", // enum: crypto, fiat
	"details": {
		"network": "SOL",
		"supported_assets": ["USDC"],
		"address": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"
	}
}

POST /payments/external_accounts response:

{
    "request_id": "a9e2c6fb-f738-4ecb-986c-befd70678707",
    "external_account_id": "107e8a2a-c835-4b76-b49d-a633d45727b9",
    "participant_code": "BENEF1",
    "platform_code": "PLAT01",
    "account_nickname": "",
    "created_at": "2024-10-11T00:52:21.865Z",
    "status": "pending",

        "address": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
        "destination_tag": ""
    }
}

XLM example request (with destination_tag) via POST /payments/external_accounts:

{
    "participant_code": "BENEF1",
    "type": "crypto",
    "details": {
	    	"network": "XLM",
    		"supported_assets": ["USDC"],

        "destination_tag": "abc123"
    }
}

Create External Account Rejection Scenarios

Scenario	Response
Beneficiary is not in an `approved` status	"participant is not approved"
Beneficiary `participant_code` does not exist	"participant {participant_code} not found"
`supported_assets` and/or `network` valid. The `supported_asset.name`/`network` combination results in a supported Payout asset. Initial list of supported currency/networks: • USDC.ALGO • USDC.ARBITRUM • USDC.AVAX • USDC.BASE • USDC.ETH (or USDC/ETH) • USDC.HBAR • USDC.POLYGON • USDC.SOL • USDC.XLM	"{supported_assets.network} is not supported"
`address` is within the Zero Hash-maintained blacklist (ie, OFAC sanctioned address)	"invalid or denied destination address"

Note: Each Beneficiary can have a maximum of 100 external accounts

7. Query External Accounts

Platforms can view all previously-connected external accounts via GET /payments/external_accounts (shown initially in a pending status below):

{
    "request_id": "4be99510-95b8-44f4-add2-ca8f943f9449",
    "message": [
        {
            "external_account_id": "2cc93b20-ee43-4877-8cdc-863e61829015",
            "account_nickname": "",
            "participant_code": "BENEF1",
            "platform_code": "PLAT01",
            "type":"crypto",
	          "details": {
		            "network": "SOL",
		            "supported_assets": ["USDC"],
		            "address": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v" 
	}
},

            "updated_at": "2024-08-15T22:39:24.171Z",
            "status_reason": "",
            "external_account_status": "pending"
            ]
        },

XLM Response example:

{
    "request_id": "4be99510-95b8-44f4-add2-ca8f943f9449",
    "message": [
        {
            "external_account_id": "2cc93b20-ee43-4877-8cdc-863e61829015",
            "account_nickname": "",
            "participant_code": "BENEF1",
            "platform_code": "PLAT01",
            "type":"crypto",
	          "details": {
								"network": "XLM",
		         		"supported_assets": ["USDC"],
			        	"address": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
   		          "destination_tag": "abc123"
	}
},
            "created_at": "2024-08-15T22:39:24.171Z",
            "updated_at": "2024-08-15T22:39:24.171Z",
            "status_reason": "",
            "external_account_status": "pending"
            ]
        },

External Account State Logic

The external account will initially enter a status of pending. Immediately and automatically after an external account submission, Zero Hash will run the address through various checks. If the checks pass, the external account will enter a state of approved. Else, rejected.

External Account Webhook Examples

pending example:

{
    "account_nickname": "",
    "external_account_id": "2cc93b20-ee43-4877-8cdc-863e61829015",
    "external_account_status": "pending",
    "participant_code": "BENEF1",
    "timestamp": 1727364785998
}

approved example:

{
    "account_nickname": "",
    "external_account_id": "2cc93b20-ee43-4877-8cdc-863e61829015",
    "external_account_status": "approved",
    "participant_code": "BENEF1",
    "timestamp": 1727364785998
}

rejected example:

{
    "account_nickname": "",
    "external_account_id": "2cc93b20-ee43-4877-8cdc-863e61829015",
    "external_account_status": "rejected",
    "participant_code": "BENEF1",
    "timestamp": 1727364785998
}

8. Initiate Payout

The Platform will initiate a Payout transaction via the POST /payments endpoint:

You can add an optional free-form description field, have left it out of the example.


{
"participant_code": "BENEF1",
"obo_participant": {
      "participant_code": "PAYOR1",
      "account_group": "PLAT01",
      "account_label": "general"
 	},
"external_account_id": "2cc93b20-ee43-4877-8cdc-863e61829015",
"asset":"USDC", // note: do not specify the network (ie USDC.BASE). the network is implied by the external account
"quoted_asset": "USD",
"total": "125.50",
"payment_type": "payout",
"description": ""
}

Note:

The participant_code will be the Beneficiary
Zero Hash will assume USD is being used to fund the trade to start
Zero Hash will validate on the following:
- The external_account_id must have the specified asset attached to it
- The platform will not have to pass a value for network on thePOST /payments, it can be inferred from the account

Response example:

{
  "request_id": "0f68333e-2114-469d-b505-c850d776e063",
  "participant_code": "BENEF1",
  "obo_participant": {
      "participant_code": "PAYOR1",
      "account_group": "PLAT01",
      "account_label": "general"
    },
  "payment_id": "0f68333e-2114-469d-b505-c850d776e061",	
  "asset": "USDC",
  "network": "SOL",
  "total": "125.50",
  "quoted_asset": "USD",
  "status": "submitted",
  "external_account_id": "2cc93b20-ee43-4877-8cdc-863e61829015",
  "created_at": "20243-08-19T23:15:05.000Z"
}

Note:

The payment_id field represents the Zero Hash payment UUID, not the blockchain hash.
The Payout will initially enter a status of submitted. The address will be run through various address checks once again. If it passes, the Payout will continue. Else, the status will become failed with a failure_reason of “address_failed_check”.

Under the hood, Zero Hash will create a trade, which will take US dollars from the Payor USD Account, account details:

Participant_code: 00SCXM
Account_group: STRP01
Account_label: PAYOR1
Asset: USD
Amount: 100,000

And convert them to USDC, resulting in a credit to the Payor USDC account, account details:

Participant_code: 00SCXM
Account_group: STRP01
Account_label: PAYOR1
Asset: USDC
Amount: 125.50

Zero Hash will then initiate a withdrawal of USDC from the Payor USDC account to the address associated with the external_account_id, associated with the Payout (payment_id).

Immediately after the withdrawal, the Payout will enter a status of posted - signifying that the USDC funds (ie, the withdrawal) has been settled on the Zero Hash ledger and the transaction has been dispersed on-chain.

Once the withdrawal has confirmed on-chain, the Payout will transition to its final status of settled.

9. Query Payouts

The Platform can view all Payouts via GET /payments (shown initially in a submitted status below):

{
  "message": [
    {
      "payment_id": "0f68333e-2114-469d-b505-c850d776e061",
      "obo_participant": {
         "participant_code": "PAYOR1",
         "account_group": "PLAT01",
         "account_label": "general"
      },      
      "payment_details": {
         	"withdrawal_id": "",
	        "trade_id": "",
	        "on_chain_transaction_id ": "",
          "network_fee_notional": "",
          "network_fee_quantity": "",
      }
      "asset": "USDC",
      "network": "SOL",
      "payment_type":"payout",
      "external_account_id": "2cc93b20-ee43-4877-8cdc-863e61829015"
      "participant_code": "BENEF1",
      "amount": "125.50",
      "status": "submitted",
      "failure_reason": "",
      "created_at": "2024-08-19T23:15:30.000Z",
      "updated_at": "2024-08-19T23:15:35.000Z"
    }
  ]
}

Platforms can also query an individual Payout via the GET /payments/id endpoint. Example:

{
  "message":
    {
      "payment_id": "0f68333e-2114-469d-b505-c850d776e061",
      "obo_participant": {
         "participant_code": "PAYOR1",
         "account_group": "PLAT01",
         "account_label": "general"
      },      
      "payment_details": {
         	"withdrawal_id": "",
	        "trade_id": "",
	        "on_chain_transaction_id ": "",
          "network_fee_notional": "",
          "network_fee_quantity": "",
      }
      "asset": "USDC",
      "network": "SOL",
      "payment_type":"payout",
      "external_account_id": "2cc93b20-ee43-4877-8cdc-863e61829015"
      "participant_code": "BENEF1",
      "amount": "125.50",
      "status": "submitted",
      "failure_reason": "",
      "created_at": "2024-08-19T23:15:30.000Z",
      "updated_at": "2024-08-19T23:15:35.000Z"
    }
}

When the withdrawal has settled on the Zero Hash ledger and directly after the on-chain transfer is sent on-chain, the Payout will transition to a posted status and will have non-null values for withdrawal_request_id, trade_id, on_chain_transaction_id, network_fee_notional, and network_fee_quantity:

{
  "message": [
    {
      "payment_id": "0f68333e-2114-469d-b505-c850d776e061",
      "obo_participant": {
         "participant_code": "PAYOR1",
         "account_group": "PLAT01",
         "account_label": "general"
    },      
      "payment_details": {
          	"withdrawal_request_id": "abc123",
          	"trade_id": "def456",
	          "on_chain_transaction_id ": "FLaUcxdNxRwnaSXp6pXeRSfANXEHouqYbqF6X1bgRxg2",
            "network_fee_notional": ".01",
            "network_fee_quantity": ".001",
            "destination_address": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
}
      "asset": "USDC",
      "network": "SOL",
      "payment_type":"payout",
      "external_account_id": "2cc93b20-ee43-4877-8cdc-863e61829015"
      "participant_code": "BENEF1",
      "amount": "125.50",
      "status": "posted",
      "failure_reason": "",
      "created_at": "2024-08-19T23:15:30.000Z",
      "updated_at": "2024-08-19T23:15:38.000Z"
    }
  ]
}

When the withdrawal has been confirmed on-chain, the Payout will transition to a settled status. Example payload:

{
  "message": [
    {
      "payment_id": "0f68333e-2114-469d-b505-c850d776e061",
      "obo_participant": {
         "participant_code": "PAYOR1",
         "account_group": "PLAT01",
         "account_label": "general"
    },      
      "payment_details": {
          	"withdrawal_request_id": "abc123",
          	"trade_id": "def456",
	          "on_chain_transaction_id ": "FLaUcxdNxRwnaSXp6pXeRSfANXEHouqYbqF6X1bgRxg2",
            "network_fee_notional": ".01",
            "network_fee_quantity": ".001",
            "destination_address": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
}

      "payment_type":"payout",
      "external_account_id": "2cc93b20-ee43-4877-8cdc-863e61829015"
      "participant_code": "BENEF1",
      "amount": "125.50",
      "status": "settled",

    }
  ]
}

Payout State Logic

The Payout will initially enter a status of submitted. From here, it's possible (yet rare) that Zero Hash has issues internally processing the transaction. If this happens, it will enter a terminal status of failed. When the transaction has been successfully broadcasted on-chain, it will enter a status of posted. A terminal status of settled is reached when the Payout has been confirmed on-chain and received by the Beneficiary.

10. Network Fee Procedure

The Platform will be paying for the network fee associated with any Payouts. There are 2 options:

Fund the network fee account. Account details:

Participant_code: PLAT01 (the Platform's participant_code)
Account_group: PLAT01
Account_label: network_fee
Asset: USD

All network fees will paid out of this account in real-time

Don’t fund the network fee account. This account will build up a payable balance

Zero Hash will add the amount of the receivable balance on this account to the end of month invoice, coupling it with the Payout usage activity amount due.

11. Email Receipt Requirements

Zero Hash requires that the Payor receives an email receipt for each Payout. We also insist that the email contain

Certain fields and values, which can be obtained using our API
Adequate support contact information

Fields

Here are the required field names and their associated API fields:

Email Receipt Field Name	Description	Example	API Location
