The SendGrid Event Webhook sends email event data as SendGrid processes it. This means you can receive data in nearly real-time, making it ideal to integrate with logging or monitoring systems.
Because the Event Webhook delivers data to your systems, it is also well-suited to backing up and storing event data within your infrastructure to meet your own data access and retention needs.
You can think about the types of events provided by the Event Webhook in two categories: deliverability events and engagement events.
Both types of events are important and should be monitored to understand the overall health of your email program. The Webhooks API allows you to configure your Event Webhook configurations.
This endpoint allows you to retrieve a single Event Webhook by ID.
If you do not pass a webhook ID to this endpoint, it will return your oldest webhook by created_date. This means the default webhook returned by this endpoint when no ID is provided will be the first one you created. This functionality allows customers who do not have multiple webhooks to use this endpoint to retrieve their only webhook, even if they do not supply an ID. If you have multiple webhooks, you can retrieve their IDs using the Get All Event Webhooks endpoint.
Your webhook will be returned with all of its settings, which include the events that will be included in the POST request by the webhook and the URL where they will be sent. If an event type is marked as true, the event webhook will send information about that event type. See the Event Webhook Reference for details about each event type.
The public_key property will be returned only for webhooks with signature verification enabled.
You may share one OAuth configuration across all your webhooks or create unique credentials for each. The OAuth properties will be returned only for webhooks with OAuth configured.
Bearer <<YOUR_API_KEY_HERE>>The on-behalf-of header allows you to make API calls from a parent account on behalf of the parent's Subusers or customer accounts. You will use the parent account's API key when using this header. When making a call on behalf of a customer account, the property value should be "account-id" followed by the customer account's ID (e.g., on-behalf-of: account-id <account-id>). When making a call on behalf of a Subuser, the property value should be the Subuser's username (e.g., on-behalf-of: <subuser-username>). See On Behalf Of for more information.
