如何从 SendGrid 获取每个 email 的所有分析？

Question

I would like to get all analytical data from SendGrid for each email using "unique args".

Currently to be able to do this, i would need to:

1. call SendGrid API to get all emails with "unique arguments"
2. from response get email ID
3. call SendGrid again based on email ID to get all "events" (clicks, opens, subscribes, unsubscribes, bounces, blocks,.. etc.)

With this approach i would make twice as much requests as needed to.

Does anyone know a way to skip step 2 and 3, and get all "events" data from just one call?

You can use Event Webhooks from SendGrid . Events are generated when the email is processed by SendGrid and email service providers. There are 2 types of events - delivery and engagement events.

Delivery events indicate the status of email delivery to the recipient. Engagement events indicate how the recipient is interacting with the email.

Delivery events include processed, dropped, delivered, deferred, and bounce.

Engagement events include open, click, spam report, unsubscribe, group unsubscribe, and group resubscribe.
