Fields

Field Name	Description
ChannelType	Type picklist Properties Filter, Group, Restricted picklist, Sort Description Required. The channel type. Valid values are: `data`—Change Data Capture channel corresponding to the selected entities. `event`—Reserved for future use.
DeveloperName	Type string Properties Filter, Group, Sort Description The unique name for the PlatformEventChannel object. The developer name doesn’t include the `__chn` custom channel suffix. For example, the developer name of the `MyChannel__chn` custom channel is `MyChannel`. 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. When creating large sets of data, always specify a unique DeveloperName for each record. If no DeveloperName is specified, performance may slow while Salesforce generates one for each record. Note
FullName	Type string Properties Create, Group, Nillable Description The full name of the associated PlatformEventChannel in Metadata API. The full name can include a namespace prefix. The full name includes the `__chn` custom channel suffix. For example, the full name of the MyChannel custom channel is `MyChannel__chn`. 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, Nillable, 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`
MasterLabel	Type string Properties Filter, Group, Sort Description The channel label. The label of this field is Label.
Metadata	Type complexvalue Properties Create, Nillable, Update Description Platform event channel 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 associated with this object. Each Developer Edition organization 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 organizations, the namespace prefix is set to the namespace prefix of the organization for all objects that support it. There is an exception if 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 organization of the package developer. In organizations that are not Developer Edition organizations, NamespacePrefix is only set for objects that are part of an installed managed package. There is no namespace prefix for all other objects.

Usage

This JSON example is the body of a REST API POST request that creates a custom channel. The corresponding REST endpoint is /services/data/47.0/tooling/sobjects/PlatformEventChannel.

1{
2  "FullName": "MyCustomChannel__chn",
3  "Metadata": {
4    "channelType": "data",
5    "label": "My Custom Channel"
6  }
7}

You can update only the FullName field and the metadata label field of a PlatformEventChannel component.

Note

You can query custom channels in SOQL over Tooling API but not the standard channel (ChangeEvents). For example, this query returns fields of channel members from all custom channels.
