Simulates a payment (sandbox)

Simulates a payer transferring to one of your templates or intents, running the provider's real rail: the payin is created, authorized and funded exactly as a production payment would be, and its outcome reaches you over the same webhooks.

Sandbox only. In any other environment the endpoint answers 403.

A payment to a template is unreferenced — the template accepts many, so the request brings its own method and amount. A payment to an intent is referenced — the intent was declared for it and already fixes both.

Use error to provoke a failure. Leaving it out simulates a payment that succeeds, though the payment authorization may still refuse it on its own validations — an amount outside the template's bounds, a payer it does not expect. That refusal happens before a payin exists, so the response comes back with no payin_id and the reason instead. Provoking those rejections is exactly how you test them.

Request Body

application/json

Payment to simulate

TypeScript Definitions

Use the request body type in TypeScript.

amountobject

Amount the payer transfers.

error?string|null

The failure to simulate. Omit it to simulate a payment that succeeds — which can still be refused, since the payment authorization runs its own validations on it either way.

Value in"risk_control" | "provider_unavailable" | "breb_timeout" | "unknown"
Example"risk_control"
methodstring

Method to pay with. Must be one the template accepts.

Value in"co_breb"
Example"co_breb"
method_params?object|null

Method-specific simulation data. For co_breb: payment_id.

payer?object|null

Who pays. Generated at random when absent.

template_idstring

Indicates the format for resource's ID
