marketingActivitiesDeleteAllExternal
Deletes all external marketing activities. Deletion is performed by a background job, as it may take a bit of time to complete if a large number of activities are to be deleted. Attempting to create or modify external activities before the job has completed will result in the create/update/upsert mutation returning an error.
marketingActivityUpsertExternal
Creates a new external marketing activity or updates an existing one. When optional fields are absent or null, associated information will be removed from an existing marketing activity.
marketingEngagementsDelete
Marks channel-level engagement data such that it no longer appears in reports.
Activity-level data cannot be deleted directly, instead the MarketingActivity itself should be deleted to
hide it from reports.
