Datadog Triggers

Overview

Triggers allow you to automatically disable a specific rule inside a VWO Feature Flag when a metric threshold is breached. For example, if errors spike, Datadog can trigger VWO to turn off the feature flag immediately.

1. Creating the Trigger URL

To set this up, you need to construct the API URL for the specific rule you want to control.

URL Format:

https://api.vwo.com/v2/accounts/{account_id}/environments/{environment_id}/features/{feature_key}/toggle

How to find these values:

• account_id: Your VWO Account ID.
• environment_id: The environment key .
• feature_key: The unique key of your feature flag.

API Reference: For details on this endpoint, see Toggle Feature Flag Status.

You will also need a Authentication header for this which you can get from Access VWO API

2. Connecting to Datadog

Once you have your URL, you need to configure it in Datadog.

1. Log in to Datadog and go to Integrations.
2. Search for Webhooks and click Configure.
3. Scroll down to create a New Webhook.
4. Name: Give it a name (e.g., vwo-kill-feature).
5. URL: Paste the Trigger URL you constructed in Step 1.
6. Payload: Paste this JSON to disable the feature:

{ "isEnabled": false }

7. Custom Headers: You must add your VWO API token here for authentication.

 { "token": "YOUR_VWO_API_TOKEN" }

8. Click Save

3. Setting up the Alert

Finally, link the webhook to a Monitor.

1. Navigate to Monitors -> New Monitor in Datadog.
2. Choose the metric you want to track (e.g., Error Rate).
3. Set your threshold (e.g., above 5%).
4. In the Notify your team section, type @webhook and select the VWO webhook you just created.
5. Click Create.

Now, whenever this alert fires, Datadog will hit the trigger and disable the feature flag in VWO.
