We recently released fmRESTor 19, along with a brief 8-minute step-by-step video on how you can use it to add a webhook to your own FileMaker database
For the case you have not heard the term yet, webhook is usually defined as a “user-defined HTTP callback”. In the simplest form it’s just a link you can click and that alone performs the action.
As an example, I took the built-in FileMaker starter solution for task management, and slightly modified it to send an e-mail when I assign someone to a task. Now whenever I assign someone to a task, that person receives a nicely formatted e-mail message with the task details, due date, and a link to click to change the task status to “Completed”.
