Jenkins Multibranch pipeline - webhook trigger and parse webhook payload in the build - jenkins

I have a multibranch pipeline which is currently using the multibranch scan webhook trigger to run a build everytime a pull request is created.
I'm trying to get jenkins to trigger the build as well as parse the payload into the build as variables but can't figure it out.
Have looked at sending two webhooks, one to trigger a build and the other to parse the payload information into the build but can't get it working.
Am looking to parse the payload so that I can then use the pull request details in my automation scripts that run at the end of a successful build.
Anyone done something like this before?

Jenkins pipeline not getting webhook from bitbucket

I am trying to setup a pipeline job to trigger on a push from my bitbucket account.
I already did this once using a freestyle job with no issue.
but I cannot get the pipeline to trigger from the webhook
I see multiple similar questions but they are all outdated and none of the solutions seem to apply.
I see the webhook in the Jenkins log
when I check the bitbucket pull request webhook log it is empty.
I tried the trick of running the build the very first time with no success
I also tried with and without the pollSCM option on - but from the help txt it seems on is the correct settings with no schedule defined!
I have no Idea where to go from here ?

send build status from jenkins to gitlab webhooks

I am trigger a webhook in gitlab once Merge request is raised, where I call a jenkins job to do a build on the pulled code.
Now my requirement is I need to send the build status/jenkins console link back to gitlab, so the reviewer can easily see what the issue is in the code and reject/approve the MR.
I tried googling a lot but I am not able to find any solution.

Jenkins and BitBucket Webhook

I am using Jenkins and BitBucket integrations.
I want to trigger a build when a PR is created. I created a webhook on bitbucket it's returning 200 response but no build is getting triggered. I have enabled "Build when a change is pushed to BitBucket" option in the build configuration.
you can use Generic Webhook Trigger Plugin.
You can integrate this plug-in with bitbucket and it will give you payload which contains all the data regarding webhook which you need to process.

Accessing the BitBucket webhook's payload in Jenkins jobs

I'm using webhooks on Bitbucket to trigger builds on Jenkins when push event occurs, for this purpose I'm using Bitbucket plugin.
My Jenkins pipeline consist of multiple cross depending tasks e.g.:
Main pipeline (triggered task)
1) build docker images
2) run tests
3) do something
The build is triggered when expected but tasks are failing because they rely on specific branch that I need to provide. Unfortunately I don't know how to access the webhook's payload that have all the information I need.
The alternative would be using Poll CMS option in Jenkins but I prefer to build on demand and not periodically.
From:
https://wiki.jenkins-ci.org/display/JENKINS/BitBucket+Plugin
they say:
Since 1.1.5 Bitbucket automatically injects the payload received by Bitbucket into the build. You can catch the payload to process it accordingly through the environmental variable $BITBUCKET_PAYLOAD.

How to get URL of pipeline job in jenkins

We are setting up a continuous delivery pipeline in Jenkins, using the build pipeline plugin.
Our deployment steps uses a proprietary deploy tool (triggered by a HTTP request from jenkins), but we need to have an additional Jenkins step for acceptance tests on the then deployed project. So our deploy tool will need to trigger the last pipeline step.
The jenkins setup for this is obvious:
For a Manually Triggered downstream build step: To add a build step
that will wait for a manual trigger:
Select the Build Pipeline Plugin, Manually Execute Downstream Project check-box
Enter the name(s) of the downstream projects in the Downstream
Project Names field. (n.b. Multiple projects can be specified by using comma, like "abc, def".)
Source: Build Pipeline Plugin
The problem is: I can't seem to find a way to trigger this downstream build through a URL.
In fact I'd need the URL in the deploy job, so I can send it to the deploy tool as a callback URL. Can anybody help?
If I understand correctly, you want to use remote access API, which to my knowledge is no different between general project or pipeline one.
Take a look here:
https://wiki.jenkins-ci.org/display/JENKINS/Remote+access+API
Submitting jobs
Jobs without parameters
You merely need to perform an HTTP POST on JENKINS_URL/job/JOBNAME/build?token=TOKEN where TOKEN is set up in the job configuration.
As stated above by #rafal S do
read a file which has list projects name for which build job has to be triggered do a curl HTTP POST on JENKINS_URL/job/${JOBNAME from the file}/build?token=TOKEN within a for loop , where for loop has list of all project names from the file you read
