With FreeAgent CRM API you can do pretty much everything you can do in FreeAgent CRM's Web Interface allowing you to interact with other applications (API stands for Application Programming Interface).
Through the GraphQL API you can perform any typical CRUD operations (create, read, update, delete) on any of your Apps whether they are our out-of-the-box Apps such as Contacts, Deals, Accounts, Tasks, or any Custom App. You can create Notes as well!
Our API documentation includes the most commonly used ones for most integrations, however, if you are looking for specific operations not included in the documentation, please reach out to support for assistance.
