Clio Manage and Clio Platform APIs

As of January 2026, there are two developer experiences used to access Clio product APIs: The Clio Manage API and the Clio Platform. This page is intended to outline the differences between the two and help you, the developer, know which to use in which circumstances.

Key Differences​

Developer Accounts​

The Clio Manage developer portal uses Manage accounts to sign in and make changes to your OAuth applications. The Clio Platform Developer portal is a separate account – you don't need a Manage account to sign up for the Clio Platform developer portal (though you can use your Clio Identity credentials to sign up and sign into the Clio Platform if you already have a Manage or Grow account).

Find out more in our docs for creating a developer account with Clio Manage and creating a Clio Platform developer account.

Client Applications​

App Creation​

The Clio Platform developer portal, located at https://developers.api.clio.com, is where you can create and manage Clio Platform OAuth applications. See the OAuth application creation doc for more information.

The Clio Manage developer portal is located at https://developers.clio.com and is the location for creating your Clio Manage OAuth Applications. See the Clio Manage OAuth application creation doc for more information.

App Capabilities​

Client applications in Clio Manage and the Clio Platform are largely similar, but have some key differences with regards to things like rate limiting and API versioning. We recommend reviewing the Clio Manage API dev docs and Clio Platform API dev docs for a detailed understanding of each system's capabilities.

Product APIs​

OAuth Applications talking to the Clio Manage API allows access to Clio Manage APIs only. Apps built on the Clio Platform can currently access Clio Grow APIs, though in the future the Clio Platform will expand to support Manage APIs and other Clio product APIs as well. If you want to build a Grow integration, use the Clio Platform; if you want to build a Manage integration, use a Clio Manage client application.

See the Clio Manage API Reference and Clio Grow API Reference for a comprehensive list of endpoints available in each product.

Multi-product integrations​

If you're interested in building an integration that talks to multiple Clio products, you'll currently need to create both a Clio Manage client application and a Clio Platform client application. Your users will also need to go through OAuth authorization for each app separately. In the future, API communication and access will be centralized on the Clio Platform, meaning your users will be able to authorize a single client application to communicate with all Clio product APIs.
