Webhook| Gitlab | jenkins pipeline |Declarative syntax

Question

I'm trying to integrate Webhook with gitlab and jenkins. I have done it via upstream downstream jobs using the URL. While trying to rece=reate the same via declarative pipeline, I'm in a stanstill

 pipeline {
  agent any
  stages {
    stage('fetchcodeFromGit') {
      steps {
        timeout(time: 30) {
          git(url: 'http:<<>>/JenkinsPipeline.git', branch: 'master', credentialsId: 'QualityAssurance', poll: true)
        }

      }
    }

Can anyone help with documents or any sample snippets?

If you choose pipeline script instead declarative pipeline, this post could be help you :

Steps:

• Configure required plugins in jenkins.
• Jenkins user and password.
• Create a jenkins job which will be triggered by your git provider. This job publish an http url ready to use. We will call webhook_url to this url.
• Configure webhook_url in webhook section of your git provider of some repository.
• Test this flow, pushing some change to your git repository or simulating it using comandline.

You can use this snippet:

pipeline {

options {
    gitLabConnection('your-gitlab-conn')
}

triggers {
    gitlab(
      triggerOnPush: false,
      triggerOnMergeRequest: true, triggerOpenMergeRequestOnPush: "both",
      triggerOnNoteRequest: true,
      noteRegex: "Jenkins please retry a build",
      skipWorkInProgressMergeRequest: false,
      ciSkip: false,
      setBuildDescription: true,
      addNoteOnMergeRequest: true,
      addCiMessage: true,
      addVoteOnMergeRequest: true,
      acceptMergeRequestOnSuccess: false,
      branchFilterType: "All",
      secretToken: "NOTVERYSECRET")
}

stages {
    ...
