What can I do with the Fiat Transfers API?

  • Paxos can accept wires from or send wires to a bank account, even if the bank account owner is not the same as the individual or institution onboarded with Paxos. This means Paxos allows wire transfers involving third-party bank accounts, subject to applicable compliance and regulatory checks.
  • Fund your Paxos corporate account or withdraw your funds to an external bank account.
  • Enable your users to directly fund their account or withdraw their funds to an external bank account.

​
How do I get the Identity ID required in requests?

  • Paxos will send you the Identity ID for your corporate account.
  • For user-based funding, Integrate the Identity API and use the corresponding endpoints.

Do I need JWS request signing?

It is recommended to have JWS request signing for fiat withdrawals. JWS request signing uses a public-key cryptography with a client-controlled private key.

When used, all API calls with this key will require a JWS signature.
