 This plugin can be used with the Job DSL Plugin. There is also an example int he [Violation Comments to GitLab Plugin](https://wiki.jenkins-ci.org/display/JENKINS/Violation+Comments+to+GitLab+Plugin) wiki page.

 This plugin can be used with the [Pipeline Multibranch Plugin](https://jenkins.io/doc/pipeline/steps/workflow-multibranch/#properties-set-job-properties). Here is an example:
 
+You can use the credentials plugin to provide the `token` from credentials.
+```groovy
+withCredentials([string(credentialsId: 'mycredentialsid', variable: 'credentialsVariable')]) {
+ properties([
+  pipelineTriggers([
+   [$class: 'GenericTrigger',
+    ...
+    token: credentialsVariable,
+    ...
+   ]
+  ])
+ ])
+}
+```
+
+Perhaps you want a different `token` for each job.
+
+```groovy
+ properties([
+  pipelineTriggers([
+   [$class: 'GenericTrigger',
+    ...
+    token: env.JOB_NAME,
+    ...
+   ]
+  ])
+ ])
+```
+
+Or have a credentials string prefixed with the job name. 
+```groovy
+withCredentials([string(credentialsId: 'mycredentialsid', variable: 'credentialsVariable')]) {
+ properties([
+  pipelineTriggers([
+   [$class: 'GenericTrigger',
+    ...
+    token: env.JOB_NAME + credentialsVariable,
+    ...
