Moov ACH is under active development and in production for multiple companies. Please star the project if you are interested in its progress. We've built an HTTP API for ACH file creation and validation. Currently we support generating and parsing all Standard Entry Class (SEC) codes. If you have layers above ACH to simplify tasks or found bugs we would appreciate an issue or pull request. Thanks!

github.com/moov-io/ach/server offers a HTTP and JSON API for creating and editing files. If you're using Go the ach.File type can be used, otherwise just send properly formatted JSON. We have an example JSON file, but each SEC type will generate differnet JSON.
This project uses Go Modules and thus requires Go 1.11+. You can download the source code and we offer tagged and released versions as well. We highly recommend you use a tagged release for production.
