Activator Plug-in 4.5


FileMaker Pro 16


This functionality is currently only available on Mac OS.

Only HTTP requests which are posted to the right web page will trigger the script. Other requests (for example for the index.html page) are ignored by the plug-in. You can now also send text only to the plug-in.

The plug-in will make the HTTP server known via Bonjour as “Troi Activator Upload Server”, allowing for easy discovery.
See the UploadData.fmp12 example file for more detailed information.


Start HTTP Server [ Select ; Result ; "Upload.fmp12" ; 
				"HTTP_TriggerScript" ; "secret" ]

This command starts the HTTP Server. When (image) data comes in it will trigger the script “HTTP_TriggerScript” in file “Upload.fmp12”. Note that this example is somewhat simplified, normally you should not use a hardcoded filename like in the above example.

Example 2

Add the following script steps:

Set Variable [ $password ; "secret" ) ]
Start HTTP Server [ Select ; Result ; Get ( FileName ) ; 
				"HTTP_TriggerScript" ; $password ; Port number: 12345 ]

This command will start the HTTP Server, with the HTTP Server listening on port 12345. Users can now send images or text data from other computers or for example an iPhone or iPad.
