## Before you begin

To fetch check exceptions, you need:

- A registered and fully onboarded Developer Account on the J.P. Morgan Chase Payments Developer Portal.

- An active project that provides you with the credentials used to make a request.

## Fetch positive pay exceptions

Send a `GET` request to `/checks/exceptions?exceptionType=POSITIVE_PAY` to fetch positive pay exceptions.
