Use the BILL v3 API

We recommend that you build all your integrations with the BILL v3 API. The BILL v2 API is currently in LTS (Long-Term Support) mode at BILL.

In this section, we explain the BILL API request and response format.

API format

A BILL endpoint includes a base URL, CRUD operation, and entity. Most endpoints are in the <API_Base_URL>/Crud/<Operation>/<Entity>.json format.

❗️

Important

There are a few exceptions to this format. See the API documentation for format details for each endpoint.
