Simulate Payment

For sandbox and demo sessions, simulate immediately marks the expected amount as received and finalizes the session.

Trigger simulation

curl -X POST https://api.plaidly.io/v1/payment_sessions/<SESSION_ID>/simulate

The endpoint returns the updated PaymentSession payload.

Verify completion

curl https://api.plaidly.io/v1/payment_sessions/<SESSION_ID>

Expected status progression for a successful simulated flow:

• pending
• finalizing
• confirmed

Webhook delivery is queued as part of completion.

Notes

• Simulation is meant for sandbox workflows and automated checks.
• Non-demo sessions cannot be simulated.
