Learn how to integrate Pay For API into your applications.

Authentication

We don't use traditional API keys. Instead, every request is authenticated by proving you made a payment on the Celo blockchain.

Include these headers in your HTTP request:

  • X-Wallet-Address: Your Celo wallet address
  • X-Payment-Token: Token symbol (e.g., cUSD)

And include the txHash in your JSON body.
