Azure pipeline

The Azure backend can trigger Azure pipelines for both self-service actions and automations, using incoming webhook triggers.

The steps shown in the image above are as follows:

1. A self-service action or automation is invoked in Port.

2. Port signs the action payload using SHA-1 with your Port clientSecret value and puts it in the X-Port-Signature request header.

   Webhook security

   Verifying the webhook request using the request headers provides the following benefits:

   • Ensures that the request payload has not been tampered with.
   • Ensures that the sender of the message is Port.
   • Ensures that the received message is not a replay of an older message.

3. Port publishes an invoked WEBHOOK via a POST request to https://dev.azure.com/{org_name}/_apis/public/distributedtask/webhooks/{webhook_name}?api-version=6.0-preview

An example flow would be:

1. A developer asks to run an Azure pipeline, using a self-service action.
2. Port sends a POST request with the action payload to the Azure webhook URL.
3. The Azure webhook receives the new action request.
4. The Azure webhook triggers the pipeline.

Define Incoming Webhook in Azure

To define an incoming webhook in Azure, follow the steps below:

1. Create the Service Connection

   • In your Azure DevOps project, go to Project Settings.
   • Under Pipelines, click on Service connections.
   • Click the Create service connection button.
   • Choose Incoming WebHook as the type.
   • Fill in the following fields:
     • Webhook Name: The webhook name e.g. "port_trigger"
     • Service connection name: The name of the service connection (e.g., "port_trigger").
     • Secret key: Enter your Port clientSecret value.
     • Headers: Type in X-Port-Signature.
   • Check Grant access to all pipelines
   • Click Save.

2. Use the Webhook in Your Pipeline

   • Add the service connection resources in the Azure pipeline yaml:

     resources:
       webhooks:
         - webhook: { webhookName }
           connection: { Service connection name }
     The complete documentation showing how to configure Azure incoming webhooks can be found here.

Configuration

When using this backend, you need to provide the following:

• ADO organization name - can be found in your URL: https://dev.azure.com/{AZURE-DEVOPS-ORG}.
• Webhook name - the name you gave to the webhook resource in the Azure yaml pipeline file.
