What is the Bolna API?

The Bolna API enables you to programmatically create, configure, and manage Voice AI agents from your own applications. Whether you are building complex workflows, automating customer support, or integrating voice capabilities into your existing products, our REST API provides everything you need. The API uses predictable, resource-oriented URLs, accepts JSON-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes and authentication.
You must have an active Bolna account to generate and use API keys. If you don’t have one, sign up here.

​
Authentication

All Bolna API endpoints require authentication using an API key. You must include this key in the Authorization header of all your HTTP requests using the Bearer scheme.
