Overview

Webhooks enable you to:

• Connect to your services.
• Alert your services when a metric alert is triggered.

Setup

Go to the Webhooks integration tile and enter the URL and name of the webhook you want to use.

Usage

To use your webhook, add @webhook-<WEBHOOK_NAME> in the text of the metric alert you want to trigger the webhook. It triggers a POST request to the URL you set with the following content in JSON format. The timeout for any individual request is 15 seconds. Datadog only issues a retry if there is an internal error (badly formed notification message), or if Datadog receives a 5XX response from the webhook endpoint. Missed connections are retried 5 times.

Note: Custom headers must be in JSON format.

To add your own custom fields to the request, you can also specify your own payload in the Payload field. If you want your payload to be URL-encoded, check the Encode as form checkbox and specify your payload in JSON format. Use the variables in the following section.

Custom variables

In addition to the list of built-in variables, you can create your own custom ones in the integration tile. You can use these variables in webhook URLs, payloads, and custom headers. A common use case is storing credentials, like usernames and passwords.

You can also hide custom variable values for extra security. To hide a value, select the hide from view checkbox when you edit or add a custom variable:

Authentication

HTTP Basic Authentication

If you want to post your webhooks to a service requiring authentication, you can use basic HTTP authentication by modifying your URL from https://my.service.example.com to https://<USERNAME>:<PASSWORD>@my.service.example.com.

OAuth 2.0 Authentication

If you want to post your webhooks to a service that requires OAuth 2.0 authentication, you can setup an Auth Method. An Auth Method includes all of the information required to obtain an OAuth token from your service. Once an Auth Method is configured and associated with a webhook, Datadog will handle obtaining the OAuth token, refreshing it if necessary, and adding it to the webhook request as a Bearer token.

To add an Auth Method, click the Auth Methods tab then click the New Auth Method button. Give the Auth Method a descriptive name, then enter the following information:

• Access Token URL
• Client ID
• Client Secret
• Scope (optional)
• Audience (optional)

Click Save to create the Auth Method. To apply this Auth Method to a webhook, go back to the Configuration tab and select an existing webhook configuration and click the Edit button. The Auth Method that you created should now appear in the Auth Method select list.

Multiple webhooks

In a monitor alert, if 2 or more webhook endpoints are notified, then a webhook queue is created on a per service level. For instance, if you reach out to PagerDuty and Slack, a retry on the Slack webhook does not affect the PagerDuty one.

However, in the PagerDuty scope, certain events always go before others—specifically, an “Acknowledge” payload always goes before “Resolution”. If an “Acknowledge” ping fails, the “Resolution” ping is queued due to the retry logic.

Examples

Sending SMS through Twilio

Use as URL: https://<ACCOUNT_ID>:<AUTH_TOKEN>@api.twilio.com/2010-04-01/Accounts/<ACCOUNT_ID>/Messages.json

and as a payload:

{
    "To": "+1347XXXXXXX",
    "From": "+1347XXXXXX",
    "Body": "$EVENT_TITLE \n Related Graph: $SNAPSHOT"
}

Replace To with your phone number and From with the one Twilio attributed to you. Check the Encode as form checkbox.

Creating an issue in Jira

Use as URL: https://<JIRA_USER_NAME>:<JIRA_PASSWORD>@<YOUR_DOMAIN>.atlassian.net/rest/api/2/issue

and as a payload:

{
    "fields": {
        "project": {
            "key": "YOUR-PROJECT-KEY"
        },
        "issuetype": {
            "name": "Task"
        },
        "description": "There's an issue. See the graph: $SNAPSHOT and event: $LINK",
        "summary": "$EVENT_TITLE"
    }
}

Do not check the “Encode as form” checkbox.
