In production, onramp orders require the customer to send MXN to a deposit CLABE. In the sandbox, you can simulate this deposit using the /ramp/order/fiat_received endpoint.
Before creating orders, ensure you have a fully onboarded customer. The bankAccountId and publicKey in your order must match the values used during that customer’s onboarding. See Testing KYC.

​
Sandbox Onramp Flow

  1. Create an onramp order via POST /ramp/order
  2. Note the orderId from the response
  3. Call POST /ramp/order/fiat_received with the orderId to simulate the fiat deposit
  4. The order will automatically progress through funded → completed status
  5. Monitor progress via webhooks or by polling the order status
