API documentation

Welcome to Billogram's API documentation!

This documentation will cover everything you need to know to integrate your service with our API. Have fun!

Our API documentation is a bit lengthy and too complex to read on such a small screen, we recommend you to visit this page on a bigger device, such as a tablet or a desktop.

1. Sign up

First off, you need to register an account. We recommend that you contact us first, so we help to setup an account in our sandbox, where it’s possible to test your code before it’s shipped into production.

2. Generate an API user

Log in to your newly created or existing account, whether it’s in the sandbox environment or not. An API user and key can be generated on the bottom of the Settings page for authorizing to the API.

3. Start developing

Billogram provides a HTTP API using the JSON format. You can use any programming language of your choice for your integration.

4. You’re done!

When you have finished and tested the integration in our sandbox environment, all you need to do is generate an API user and key in your company’s production account, and then you’re done! Now you’re all set to start invoicing!
