BILL API Platform
Discover how to leverage the BILL API features in your integrations
BILL is a cloud-based financial operations platform for an organization's accounts payable (AP), accounts receivable (AR), and spend & expense (S&E) automation.
The BILL v3 API gives you access to the same infrastructure that powers the AP, AR, and S&E products. In addition, you can receive real-time event notifications with webhooks.
BILL v3 API capabilities
The BILL v3 API follows the REST architecture. We use all the standard REST verbs (GET, POST, PUT, PATCH, and DELETE) and provide HTTP response codes.
