Core concepts

The Checks API is tailored for business operations, system integrators, and service providers seeking a unified Check API for local processing. This API facilitates various operations essential for managing the complete Check payment lifecycle.

Instant response 

Checks sends acknowledgements in the synchronous response. If you’ve enabled notifications, we’ll send the final status through a webhook or asynchronous notification. You can also use the transaction status product to confirm the status of any transaction.

Encryption and security 

The Checks API utilizes OAuth 2.0 for authentication to help provide secure access.

Throttling and TPS limits 

The J.P. Morgan Payments Platform is designed to support scalability and accommodate increased processing demands and traffic surges.
