The Codat public API provides secure access to contributed business data from your SME customers, all mapped to our unique standardized data model.

A single REST API with over 40 different groups of endpoints, the API supports a wide range of operations and HTTP methods, including:

• Pulling data—GET methods
• Pushing data—POST methods
• Updating data—PUT methods

Requests and responses are in JSON only, and the API implements robust error handling.

Complex business data—like orders, payments and taxes—is represented in a wide range of data types using logical and consistent schemas.

The API is secured using an OAuth 2.0 authorization flow.

Over 30 different integrations provide pre-built, standardized connectivity between the Codat API and supported accounting, banking, eCommerce, PoS, and payment software (both cloud and on-premise).

If you want to build to our API directly, you can explore the API endpoints and schemas in our Swagger documentation.
