How to trigger the azure devops build pipeline using azure logic app

Question

I am trying to setup a slack integration to trigger the azure build pipeline using azure logic app.

I have completed the setup for slack command to point to logic app http request endpoint url. however i am unable to extract the parameter value passed with slack command as argument and set that as parameter to pass it to queue a build (azure devops)

Slack command:

/trigger-build ansible_verbosity=2 pa__name=max6 pa__tag=deploy pa_deployment_override=true version=5.8.3

Below are the HTTP request received output

            }
        ]
    }
}

The parameters which I had passed are stored as "text".

{
                "key": "text",
                "value": "ansible_verbosity=2 pa_internal_name=max6 pa_deploy_tag=deploy pa_deployment_patch_override=true version=5.8.3"
            },

Need Help in extracting the values and setting it as a parameters to pass it to queue a build (azure devops)

Hello Syed Aman

Based on the shared issue description, I have understood that you are trying to queue DevOps build through logic app and by pulling the specific Key value of text from the HTTP request trigger output.

To test this, we have created a consumption-based logic app using the above shared JSON as Input and thereby using the ParseJSON action and For_each loop to pull the text parameter key value.

Here is screenshot of our logic app :

Here are the expressions that we have used in our logic app:

1. In Condition action : items('For_each')?['key] = "test"
2. Under true branch and in Set Variable action : items('For_each')?['value']

Here is the sample output for your reference :

Feel free to reach back to me if you have any further questions on this.
