Moov's mission is to give developers an easy way to create and integrate bank processing into their own software products. Our open source projects are each focused on solving a single responsibility in financial services and designed around performance, scalability, and ease-of-use.
Bai2 implements a reader, writer, and validator for the Cash Management Balance Reporting Specifications Version 2 developed by Bank Administration Institute (BAI). This project offers a HTTP server in a Docker image and a Go package github.com/moov-io/bai2
.
Moov Bai2 is being used in pre-production and production environments. We are actively improving the library and refactoring to make the interfaces better for developers. Please star the project if you are interested in its progress. If you have layers above Bai2 to simplify tasks, perform business operations, or found bugs we would appreciate an issue or pull request. Thanks!
The Bai2 project implements an HTTP server and Go library for creating and modifying files in bai 2 format, which developed a generic format and widely accepted by most of the Banks in USA.
We publish a public Docker image moov/bai2
on Docker Hub with each tagged release of Bai2. No configuration is required to serve on :8208
.
Pull & start the Docker image:
docker pull moov/bai2:latest
docker run -p 8208:8208 moov/bai2:latest web
Upload a file and parse it:
curl -X POST --form "input=@./data/sample.txt" http://localhost:8208/parse
{"status":"valid file"}
Print a file after parse:
curl -X POST --form "input=@./data/sample.txt" http://localhost:8208/print

By design, Bai2 does not persist (save) any data about the files or entry details created. The only storage occurs in memory of the process and upon restart Bai2 will have no files or data saved. Also, no in-memory encryption of the data is performed.

This project uses Go Modules and Go v1.18 or newer. 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.
To make a release of bai2 simply open a pull request with CHANGELOG.md
and version.go
updated with the next version number and details. You'll also need to push the tag (i.e. git push origin v1.0.0
) to origin in order for CI to make the release.
We maintain a comprehensive suite of unit tests and recommend table-driven testing when a particular function warrants several very similar test cases. To run all test files in the current directory, use go test
. Current overall coverage can be found on Codecov.
We currently run fuzzing over ACH in the form of a Github Action. Please report crashes examples to oss@moov.io
. Thanks!
