Acquire Access Token

To invoke the web SDK for crypto buy/sell, crypto withdrawals, and fiat deposit/withdraw, you must request a temporary access token. This should be done in advance of rendering the relevant page. You can obtain an access token by making requests to POST /client_auth_token.

Generating an access token must be initiated on the server side. You must provide a <participant_code> query parameter for the customer who will enter the transaction. This enables Zero Hash to uniquely identify participants and create a tie between our system and yours.

All API requests are authenticated using your signed API key.
