Datadog
Adding a Contact
Datadog Events are triggered using the Application Keys integrations, available from the Organization Settings ➡️ API Keys section of your Datadog portal. All you'll need is an API Key to enable Datadog Events.
In Datadog
In the Datadog portal, navigate to the Organization Settings ➡️ API Keys section.
Make sure you have at least one API Key generated. If not, select New Key to generate a new key:

After creating the key, click the Copy button to copy the key to your clipboard.
In the Portal
You can add a new Datadog Contact from the Contacts ➡️ Manage ➡️ Contacts section of the Portal:

Select Datadog from the Contact Type drop-down, enter the API Key in the API Key field, select your preferred API Endpoint region, select a Frequency, and select one or more Contact Groups to associate with this new contact.
After clicking Add Contact, you'll receive a confirmation message with a confirmation link that you'll need to click on to confirm your contact.

If you don't receive the confirmation message for some reason, you can also click the Resend Auth option to resend the confirmation message. Once a contact is confirmed, it will be ready to use.
The Frequency setting only applies to RBL Monitoring and will be removed in a future update. Other products such as Certificate Monitoring have their own alerting options.
