A webhook is a custom callback over HTTP used to setup communication between applications. They provide a way to automatically notify other applications when an event has occurred in your application in the form of an HTTP post payload. This eliminates the need to poll your application to check for new events – the application will alert you when there's something new! Webhooks in FlexDeploy can be used to trigger actions in FlexDeploy based on events happening in other applications, thus eliminating some manual actions. For example, you can setup a webhook to build a project immediately after a push occurs in your SCM. This is just one example, and FlexDeploy's model offers flexibility in what you can accomplish with webhooks.
Webhook Flow
There are two key aspects to webhooks in FlexDeploy; Providers and Functions. The flow diagram below illustrates how these different pieces interact with each other for a given webhook message:

| Info | ||
|---|---|---|

The URIs after the base '/flexdeploy/webhooks/v1' uri are purely by convention and any uri can be used. In this example we had "git/push" but "something/random" would have worked exactly the same. The benefit of this approach is that you can direct 90% of your Git Repositories to a standard 'git/push' function while maybe the remaining 10% have more complex logic and need to be directed to a separate "git/complex" function. Also note that query parameters can be passed and accessed from the scripts but are not included in the URI matching. I.E. git/push?projectId=123 will still match to git/push. |
Navigation
Webhooks can be accessed from Administration → Integrations → Webhooks. This page will show all the Webhook Functions configured in FlexDeploy. Webhook Providers can be accessed from the 
button on the functions page. Click 
to view the results of any received webhooks, or to resubmit them.
