Ach API

This is the Integration API Specification for the ACH RealTime Processing API.

This specification instructs programmers in writing software to send transactions to Check Commerce and receive information about transactions from Check Commerce.

This specification also describes file formats used to transmit multiple transactions in a batch, which can be useful to programmers as well as those who wish to transfer the files manually on the Merchant Center website.

These are the base links to access the API.
