List Custom Channels and Channel Members

To perform SOQL queries, make a REST query call or use the Query Editor in the Developer Console with the Tooling API option selected. To make REST calls using Postman, set up Postman with the Salesforce Platform APIs collection. See Quick Start: Connect Postman to Salesforce in Trailhead.

Perform a GET request to this endpoint with the SOQL query appended.

/services/data/v64.0/tooling/query?q=<query>

This query returns all the custom channels. The query results in this page are based on the Order_Channel__chn channel.

SELECT Id, DeveloperName, ChannelType, MasterLabel FROM PlatformEventChannel

If you're using Postman, expand Event Platform | Custom Channels, and then click List event channels.

Sample result:

And this query returns all the channel members.

SELECT Id, DeveloperName,EventChannel, SelectedEntity FROM PlatformEventChannelMember
