Documentation
Column N.A. is the first nationally chartered bank created to serve developers and builders,
offering financial capabilities in a developer first way.
We continue building as you build and your feedback is welcome! Honestly... tell us everything, the more critical, the better. We want to hear what you hate, what you like and what you want. It's been a labor of love and we hope you find it useful!
For feedback email us at developers@column.com. For technical support email us at support@column.com, and if you want to complain to the CEO (or say nice things), you can email me at william@column.com.
Share what you love, hate, or want to see next.
Get help from our team when you run into an issue.
Complaints or compliments — straight to William.
Built on OpenAPI
Column's API is defined by an OpenAPI spec↗. Use it to generate type-safe client SDKs in any language, import it into tools like Postman↗ or Insomnia↗ to explore endpoints, or mock the API locally for testing. The spec is versioned, so you can pin your integration and track changes over time.
Recommended Guides
