Fields

Field Name	Description
DeveloperName	Type string Properties Filter, Group, Sort Description The unique name for the PlatformEventChannelMember object. This name can contain only underscores and alphanumeric characters, and must be unique in your org. It must begin with a letter, not include spaces, not end with an underscore, and not contain two consecutive underscores. This field is automatically generated, but you can supply your own value if you create the record using the API. The developer name is in the format `ChannelName_EventName`. If your channel member name contains a custom channel name to make it unique, ensure to replace the double underscores in the name with one underscore. For example, the developer name of a member of the `MyChannel__chn` custom channel is `MyChannel_chn_AccountChangeEvent`. And the developer name of a member of the default standard channel is `ChangeEvents_AccountChangeEvent`. When creating large sets of data, always specify a unique DeveloperName for each record. If no DeveloperName is specified, performance slows down while Salesforce generates one for each record. Only users with View DeveloperName OR View Setup and Configuration permission can view, group, sort, and filter this field. Note
EventChannel	Type picklist Properties Filter, Group, Nillable, Restricted picklist, Sort Description The name of a channel. For the standard channel, the name is `ChangeEvents`. For a custom channel, the name is in this format: `MyChannel__chn`.
FilterExpression	Type textarea Properties Nillable Description An expression that is used to filter the stream of events and deliver only the events that match specific criteria. The filter expression can contain one or more field-value expressions. The filter expression format is based on SOQL and supports a subset of SOQL operators and field types. For example, this filter expression delivers only events that contain the City__c field with a value of 'San Francisco'. `City__c = 'San Francisco'` For more information, see Filter Your Stream of Platform Events with Channels in the Platform Events Developer Guide and Filter Your Stream of Change Events with Channels in the Change Data Capture Developer Guide. Available in API version 56.0 and later.
FullName	Type string Properties Create, Group, Nillable Description The full name of the associated PlatformEventChannelMember object in Metadata API. The full name is in the format `ChannelName_EventName` and can include a namespace prefix. Two consecutive underscores in full names designate either a component name suffix or a namespace prefix. In all other cases, two consecutive underscores aren’t supported in full names. If your channel member name contains a custom channel name to make it unique, be sure to replace the double underscores in the name with one underscore. For example, the member name would be `MyChannel_chn_AccountChangeEvent` and not `MyChannel__chn_AccountChangeEvent`. Query this field only if the query result contains no more than one record. Otherwise, an error is returned. If more than one record exists, use multiple queries to retrieve the records. This limit protects performance.
Language	Type picklist Properties Defaulted on create, Filter, Group, Restricted picklist, Sort Description The language of the MasterLabel.
ManageableState	Type ManageableState enumerated list Properties Filter, Group, Nillable, Restricted picklist, Sort Description Indicates the manageable state of the specified component that is contained in a package: `beta` `deleted` `deprecated` `deprecatedEditable` `installed` `installedEditable` `released` `unmanaged`
Metadata	Type complexvalue Properties Create, Nillable, Update Description Platform event channel member metadata. Query this field only if the query result contains no more than one record. Otherwise, an error is returned. If more than one record exists, use multiple queries to retrieve the records. This limit protects performance.
NamespacePrefix	Type string Properties Filter, Group, Nillable, Sort Description The namespace prefix that is associated with this object. Each Developer Edition org that creates a managed package has a unique namespace prefix. Limit: 15 characters. You can refer to a component in a managed package by using the `namespacePrefix__componentName` notation. The namespace prefix can have one of the following values. In Developer Edition orgs, NamespacePrefix is set to the namespace prefix of the org for all objects that support it, unless an object is in an installed managed package. In that case, the object has the namespace prefix of the installed managed package. This field’s value is the namespace prefix of the Developer Edition org of the package developer. In orgs that aren’t Developer Edition orgs, NamespacePrefix is set only for objects that are part of an installed managed package. All other objects have no namespace prefix.
SelectedEntity	Type picklist Properties Filter, Group, Nillable, Restricted picklist, Sort Description The change event name of an entity selected for Change Data Capture notifications. For example, for the Account standard object, the name is `AccountChangeEvent`, or for a custom object MyObject__c, the name is `MyObject__ChangeEvent`.

Usage

This JSON example is the body of a REST API POST request. It adds a member to a custom channel named SalesEvents__chn. The corresponding REST endpoint is /services/data/v68.0/tooling/sobjects/PlatformEventChannelMember.

1{
2  "FullName": "SalesEvents_chn_AccountChangeEvent",
3  "Metadata": {
4    "eventChannel": "SalesEvents__chn",
5    "selectedEntity": "AccountChangeEvent"
6  }
7}

To add a member to the ChangeEvents default channel, the request body looks as follows.

1{
2  "FullName": "ChangeEvents_AccountChangeEvent",
3  "Metadata": {
4    "eventChannel": "ChangeEvents",
5    "selectedEntity": "AccountChangeEvent"
6  }
7}

You can query PlatformEventChannelMember in SOQL over Tooling API. For example, this query returns fields of all channel members on all channels.

1SELECT Id,DeveloperName,EventChannel,SelectedEntity FROM PlatformEventChannelMember

For custom channels, the EventChannel value that the query returns is the channel ID, which starts with the 0YL prefix.

Note

You can configure a channel member to include extra fields in change events as part of Change Data Capture Enrichment. For more information, see Example: Add Event Enrichment Fields with Tooling API in the Change Data Capture Developer Guide.
