Workiva offers many Application Programming Interfaces (APIs). An API is a set of protocols that allow for building software applications that access the features and data of an application or their service. APIs are commonly used by developers to integrate different software systems, allowing them to share data and functionality. APIs make it easier for developers to create new applications that can interact with existing systems. Workiva's APIs are free to use and span the Workiva Platform. They are routinely expanded upon and new endpoints are frequently added.

Many of the Workiva API endpoints have a corresponding dedicated Command available in the Workiva Connector. However, some API endpoints may not currently have a dedicated built-in Command in Chains. These endpoints can still be utilized within Chains using the HTTP Requests Connector.

Workiva uses a unified, date based versioning system to ensure stable and predictable integrations as the Platform evolves. Each API version is identified by a YYYY‑MM‑DD release date through the X‑Version header. For full details, see the Versioning, 2026-01-01 Upgrade Guide, and API Version Best Practices documentation.

Detailed documentation about API changes are provided in the Changelog.

It is leading practice to include error handling and rate usage monitoring in your applications. If you do reach a limit, the Workiva APIs will respond with `429 Too Many Requests` status code. You can find information on the limits for each API in the "Limits" section of the API documentation. For example, you can find the Platform API Limits here. You are also encouraged to review the API Rate Limits documentation for more details.
