Using the API

Connect external applications to your Billdu account via the API

The Billdu API lets you connect external applications to your Billdu account to create clients, invoices, and orders programmatically.

Available on the website only. Accessible to account owners only.

How it works

  • Billdu's API uses one-way communication - external apps can send data into Billdu, but not pull data out

  • To connect, you need your unique API key and API secret (which acts as a password)

  • Each business in your Billdu account has its own key and secret

  • Find your API key and secret under SettingsAPI on the Billdu website

What you can do with the API

  • Create clients

  • Create documents (invoices, orders)

  • Send documents by email

Documentation and resources

Note: For issues or feature requests, use the issues section in the API documentation repository on GitHub.
