An extensible, highly-available, distributed, and fault-tolerant ACH uploader and downloader. ACH Gateway creates events for outside services and transforms files prior to upload to fit real-world requirements of production systems.
If you believe you have identified a security vulnerability please responsibly report the issue as via email to security@moov.io. Please do not post it to a public issue tracker.
Read through the project docs to gain an understanding of this project's purpose and how to run it.
We publish a public Docker image moov/achgateway from Docker Hub or use this repository. No configuration is required to serve on :8484 and metrics at :9494/metrics in Prometheus format.
Start achgateway and an FTP server:
# Inside of ./examples/getting-started/
$ docker-compose up achgateway

achgateway accepts files over HTTP and Kafka to queue them up for upload at a Nacha cutoff time. This allows systems and humans to publish files and have them be optimized for upload. achgateway is inspired by the work done in moov-io/paygate and is used in production at Moov.
This project is used in production at multiple companies and has reached a stable status. We are looking to improve the configuration of ACHGateway and looking for feedback from real-world usage. Please reach out and share your story.

Yes please! Please review our Contributing guide and Code of Conduct to get started! Checkout our issues for first time contributors for something to help out with.
This project uses Go Modules and uses Go 1.19 or higher. See Golang's install instructions for help setting up Go. 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.
Improving test coverage is a great candidate for new contributors and allows the project to move more quickly by reducing regression issues that might not be caught before a release is pushed out to our users. One great way to improve coverage is by adding edge cases and different inputs to functions (or contributing and running fuzzers).
Tests can run processes (like SQLite databases), but should only do so locally.
