Before you begin

To initiate a JPM Coin System deposit, you need:

A registered and fully onboarded Developer Account on the J.P. Morgan Payments Developer Portal.
An active project that provides you with the credentials used to make a request.
A J.P. Morgan Blockchain Deposit Account (BDA) opened at J.P. Morgan Chase Bank, N.A.
A Demand Deposit Account (DDA) opened in an approved funding location in which you want to perform a JPM Coin System transaction.

Tip

In addition to regular Demand Deposit Accounts (DDA), select Client Money Accounts (CMA) and Mortgage Servicing Accounts (MSA) are supported by this product, subject to J.P. Morgan review.

Create and send a JPM Coin System deposit request payload

Request payloads for the Global Payments API have optional and required fields. The full request payload is sent using a POST HTTP request.
