Note: Zapier's Slack app supports a limited set of OAuth scopes/permissions, thus many of Slack's API endpoints aren't currently feasible.

API docs for Slack are located here https://api.slack.com/methods

Requests can only be made to domains associated by this application.

These params will be URL-encoded and appended to the URL when making the request.

Authentication headers are included automatically

Zapier will apply these optional headers and values to the request in addition to any headers created as part of the authentication mechanism.

In order to trigger when emails are opened, this must be paired with a separate Zap using the Send Outbound Email action, with the Enable Read Receipts? field set to True.

To test with a live email, send an email to yourself using your Send Outbound Email action (with read receipts enabled) and open it, then test this trigger immediately for samples. If you don't need to test with live data, click Skip Test to use static test data.
