In the Secure Source Manager web interface, navigate to the repository you want
to create a webhook for.
Click Settings.
Click Webhooks, and then click Add webhook.
In the Hook ID field, enter an ID for the webhook.
In the Target URL field, enter the Webhook URL. For example, if you want
to trigger a build in Jenkins, you could
Set up a webhook trigger, and then enter
the Jenkins trigger URL here to trigger your build in Jenkins.
If the Webhook URL contains your key and secret values entered when you
created your webhook trigger, remove them from the end of the target URL
and copy them to the Sensitive Query String field.
To locate your key and secret in your webhook URL, look for the text
starting with key=
For example, given the following URL:
https://cloudbuild.googleapis.com/v1/projects/my-project/triggers/test-trigger:webhook?key=eitIfKhYnv0LrkdsyHqIros8fbsheKRIslfsdngf&secret=Hello%20Secret%20Manager
Copy and remove the portion starting with the question mark
?key=... from the Target URL field. Then remove the initial question
mark, move the remaining portion key=... to the Sensitive Query String
field.
In the Trigger on section, select one of the following:
Push: to trigger on a push to the repository.
Pull request state changed: to trigger on a change in the pull
request state.
If you selected Push, then you can enter an allowlist for push events in
the Branch filter field.
The Branch filter field uses the glob pattern and only operations on the
matched branches will cause a build trigger. If the field is empty or *,
then push events for all branches are reported. For information on syntax,
see the glob documentation.
Click Add webhook.
The webhook is displayed in the Webhooks page.
Test your webhook
In the Secure Source Manager Webhooks page, click the webhook you want
to test.
Go to the bottom of the page and click Test delivery.
A placeholder event is added to the delivery queue. It might take a few
seconds before it shows up in the delivery history.
You can also use a git command to push or merge a pull request to test the
webhook.
Check the status of the triggered build or event in the build history of the
service where you configured your webhook trigger.
You can also view the Request and Response to the test delivery
in the Recent deliveries section of the Secure Source Manager
webhook page after you send your first test delivery.
Substitute Cloud Build YAML variables with payload data
If you're using webhooks to connect to Cloud Build, you can substitute
Cloud Build YAML variables with Secure Source Manager webhook payload
data.
In the Secure Source Manager Webhooks page, in the Recent deliveries
section, click the top row.
The Request header and content sent by the webhook payload is displayed.
Navigate to the Cloud Build dashboard, and then click Triggers.
Click the trigger you want to configure.
In the Advanced section, under Substitution variables, click
+ Add variable.
Enter the name and value of the variable. The value prefix is body.
For example, to substitute _REPO_URL with the payload data field
repository.clone_url and _COMMIT_SHA with latest commit sha in
Cloud Build YAML, enter the following names and values:
Variable 1: _REPO_URL Value 1: $(body.repository.clone_url)
Variable 2: _COMMIT_SHA Value 2: $(body.after)
The Cloud Build YAML file resembles the following:
