Webhooks allow you to receive HTTP callbacks when incidents are created, updated and deleted. Details about the event are sent to your specified URL, such as Slack or your own custom PagerDuty webhook processor.

Migrate to V3 Webhook Subscriptions

• If you are currently using V1/V2 webhook extensions and need to migrate them to V3 webhook subscriptions, please follow our migration guide.
• V1 webhook extensions will be deprecated by November 13, 2021 and V2 by March 31, 2022.

Add a V3 Webhook Subscription

🚧

Required User Permissions

• All users, with the exception of Limited Stakeholders, can add V3 Webhook subscriptions.
• Restricted Access Base Role: If you are a user with a Restricted Access base role and Manager team role, then you can create and manage your V3 webhooks by going directly to the V3 webhooks management page at [YOUR-SUBDOMAIN].pagerduty.com/integrations/webhooks.

1. Navigate to Integrations Generic Webhooks V3. Click Add Webhook in the Overview tab.
2. You will then be directed to the Mapping tab. Enter the Webhook URL, under Scope Type select Service or Team based on your preferences, under Scope select the desired service or team, and then enter a Description. Under Events to Send, select either Send all events or Send selected events. If you select Send selected events, you will then be prompted to check the event types you would like sent.
3. Click Add Webhook.

Supported Resources and Event Types

The following resources and event types are available with V3 webhooks. Additional event types may be added to this list over time.

V3 Webhook Subscriptions versus V1/V2 Webhook Extensions

Conceptually, V3 webhook subscriptions and V1/V2 generic webhook extensions are similar; however, there are some differences:

• V3 Webhook Subscription: A subscription configured to send a webhook to an endpoint every time an event happens on an incident and within a specific scope (team or service) that you care about.
• V1/V2 Generic Webhook Extension: An endpoint configured to be sent webhooks every time an incident is created, updated, or deleted.

Key Differences

Payload

The final payload of the webhook differs between V1/V2 and V3. The destination service of the webhook will need to be tweaked to handle the new payload.

• An explanation of a V3 payload is shown here.
• An explanation of a V2 payload is shown here.

Custom Headers

Currently, V3 webhook subscriptions do not support the custom headers that are available in V2 webhooks, however this capability is in development.

Request Headers

The user-agent header in the request displays which webhooks version was used: PagerDuty-Webhook/V2.0 for V2 and PagerDuty-Webhook/V3.0 for V3.

V3 webhook subscriptions also introduce two new headers: x-webhook-subscription and x-pagerduty-signature.

Migrating from V1/V2 Generic Extensions to V3 Webhook Subscriptions

The following guide explains how to migrate existing V1/V2 generic webhook extensions to V3 webhook subscriptions. V1 webhook extensions will be deprecated by November 13, 2021 and V2 by March 31, 2022.

🚧

Required User Permissions

Admins or Account Owners can migrate an account’s V1/V2 webhook extensions to V3 webhook subscriptions.

Step 1: Generate an API Key

1. Generate an API Key by navigating to Integrations API Access Keys +Create New API Key.
2. Enter a Description that will help you identify the key later on. If you would like it to be read-only, check the Read-only option. Click Create Key.
3. A unique API key will be generated. Copy it to a safe place, as you will not have access to copy this key again. Once it has been copied, click Close. If you lose a key you will need to delete it and create a new one.

Step 2: Get a List of Existing Webhooks

Get a list of the existing V2 webhooks using the extensions API endpoint. It may be helpful to set the query field in the request to webhook to filter by Generic Webhooks only.

In this example, when the GET /extensions endpoint is called, the response contains a list containing a single extension:

{
    "extensions": [
        {
            "endpoint_url": "https://example.com/webhooks_go_here",
            "name": "My Webhook",
            "config": {
                "headers": null,
                "referer": "https://subdomain.pagerduty.com/extensions"
            },
            "extension_schema": {
                "id": "PJFWPEP",
                "type": "extension_schema_reference",
                "summary": "Generic V2 Webhook",
                "self": "https://api.pagerduty.com/extension_schemas/PJFWPEP",
                "html_url": null
            },
            "extension_objects": [
                {
                    "id": "PYKHOXQ",
                    "type": "service_reference",
                    "summary": "My Application Service",
                    "self": "https://api.pagerduty.com/services/PYKHOXQ",
                    "html_url": "https://subdomain.pagerduty.com/service-directory/PYKHOXQ"
                }
            ],
            "id": "PUGLEKG",
            "type": "webhook",
            "summary": "My Webhook",
            "self": "https://api.pd-staging.com/webhooks/PUGLEKG",
            "html_url": null
        }
    ],
    "query": "webhook",
    "limit": 25,
    "offset": 0,
    "total": null,
    "more": false
}

Step 3: Note the Important Fields

In the response of GET /extensions, for each extension in the extensions array, take note of the endpoint_url, name, and id. To get the service that the extension is linked with, take the id and type inside the extension_objects array.

From the response in Step 1, take note of lines 4, 5, 19, 20, and 26.

Step 4: Decide on Event Types

V3 webhook subscriptions introduce a new way to refine subscriptions with events types. Before creating a new V3 webhook subscription, event types will need to be selected.

📘

Note

In order to receive the same data as a V2 generic webhook extension, all V3 event types will need to be added.

To replicate the existing behavior of the V2 generic webhook extension, all of the available event_types will be used:

"incident.acknowledged"
"incident.annotated"
"incident.delegated"
"incident.escalated"
"incident.priority_updated"
"incident.reassigned"
"incident.reopened"
"incident.resolved"
"incident.responder.added"
"incident.responder.replied"
"incident.triggered"
"incident.unacknowledged"

Step 5: Create a New V3 Webhook Subscription

Using the webhooks subscriptions API endpoint, a webhook subscription can now be created. A mapping of the old V2 request to the new V3 request is described below.

The new request to POST /webhook_subscriptions will look like the following:

{
    "webhook_subscription": {
        "delivery_method": {
            "type": "http_delivery_method",
            "url": "https://example.com/webhooks_go_here"
        },
        "description": "My Webhook"
        "events": [
            "incident.acknowledged"
            "incident.annotated",
            "incident.delegated",
            "incident.escalated",
            "incident.priority_updated",
            "incident.reassigned",
            "incident.reopened",
            "incident.resolved",
            "incident.responder.added",
            "incident.responder.replied",
            "incident.triggered",
            "incident.unacknowledged"
        ],
        "filter": {
            "id": "PYKHOXQ",
            "type": "service_reference"
        },
        "type": "webhook_subscription"
    }
}

Step 6: Cleanup

At this point, a new V3 webhook subscription has been created that will replicate the existing V2 generic webhook extension. Duplicate webhooks will be sent so long as both V2 and V3 subscriptions exist. Once it is confirmed that the new V3 webhook subscription is functional, the old V2 generic webhook extension should be deleted using the id found in Step 1.

In the example, the old extension id is found on line 26 from Step 1.
