How do I create a GitLab webhook?

Question

I've read that GitLab is capable of sending messages to other servers via "web hooks" but I can't find where one would create one.

Can someone point me in the right direction?

Answer 1

All the answers I've found in official documentation and on Stack Overflow for finding web hooks are incorrect. The admin area > hooks page does NOT contain web hooks. It contains system hooks, which fire when you create/delete projects and users and things like that. This is not what you want.

To find your web hooks, go to the specific project > settings > web hooks (on sidebar in GitLab 6.1.0) page. These will fire on post-receive for the project in question. You can use a service like RequestBin to see what the payload looks like and to ensure you're firing these off correctly for debugging purposes.

Answer 2

With version 8.16.1, I found the web hooks under

specific project > settings > integrations

Answer 3

For group level hooks:

visit: https://gitlab.com/groups/<yourgroup>/hooks

For group project level hooks:

visit: https://gitlab.com/yourgroup/yourproject/hooks

Answer 4

You can see an example of GitLab system hook, with a web_hook.rb creation in this GitHub project.

In gitlab, as admin, go to "Hooks" tab, create hook as: http://your.ip.goes.here:8000

or change the port on line 175 of the script.

For web hooks, see Jamey's more accurate answer.

You can inspect the result of a webhook with a service like RequestBin.
Another example of webhook interpretation: this question.

Be aware though that a few issues remain with gitlab webhook:

• it is not always firing
• There's no URL nor namespace key present on system's webhook
