The Claris® FileMaker® Data API is an application programming interface (API) that allows web services to access databases hosted by Claris FileMaker Server™ or a Claris FileMaker Cloud® product. Because this API conforms to Representational State Transfer (REST) architecture, the FileMaker Data API is a REST API.
Your web service or application calls the FileMaker Data API to obtain an authentication token for access to a hosted database, then uses that token in subsequent calls to create records, update records, delete records, and perform find requests.
The FileMaker Data API returns data in JavaScript Object Notation (JSON), a text format that is commonly used with REST APIs because it is independent of specific programming language formats.
