Moneybag documentation

Build a reliable payment integration

Moneybag documentation is organized around the work your integration must complete: create a checkout, redirect the customer, verify the final state, process webhooks safely, and prepare for production review.

Recommended path

  1. Create and verify a sandbox account.
  2. Store the one-time merchant key in server-side secret storage.
  3. Create a checkout from your backend.
  4. Send the customer to Moneybag hosted checkout.
  5. Verify the transaction from your backend after the customer returns.
  6. Validate webhooks and handle duplicate delivery idempotently.
  7. Complete the production-readiness review.

What is available today

The API Reference renders the reviewed, backend-derived sandbox contract. The API Lab executes only those reviewed operations, and the Developer workspace provides sandbox key and webhook tools without exposing retained credentials to page scripts. The AI Integration Kit packages the same contract boundaries for coding agents.
