Developer Documentation

The Fiatsend API is documented separately at developer.fiatsend.com.

Use the developer portal as the source of truth for:

  • API authentication and production access.
  • Endpoint and payload definitions.
  • SDKs, sandbox testing, rate limits, and error handling.
  • Webhook delivery and signature verification.

The standard documentation site intentionally does not duplicate those materials. Keeping one technical source of truth prevents integration drift and ensures developers always see the current contract.
