Web integration alternatives
If you aren't experienced using REST APIs, consider the following alternatives to use your FileMaker custom app on the internet.
Claris Connect: As a cloud-based integration platform, Claris Connect provides an easier way to connect your FileMaker custom app to web apps and services.
See Claris Connect.
FileMaker WebDirect: Web users connect to your hosted database to view, edit, sort, or search records if you give them access privileges. They don't need to install additional software—just compatible web browser software and access to the internet or an intranet. The user interface resembles the desktop FileMaker Pro application. The webpages and forms that the web user interacts with are dependent on the layouts and views defined in the FileMaker Pro database.
See FileMaker WebDirect Guide.
Static publishing: If your data rarely changes, or if you don't want users to have a live connection to your database, you can use static publishing. With static publishing, you export FileMaker Pro data to create a webpage that you can further customize with HTML. The webpage doesn't change when information in your database changes, and users don't connect to your database.
See Publishing data on static webpages in FileMaker Pro Help.
Custom Web Publishing: To integrate your FileMaker Pro database with a custom website, use the Custom Web Publishing technologies provided by FileMaker Server.
