Confused about "References"?
Let us know how we can improve our documentation:
LAST EDIT Aug 25 2021
When you add a user or a collection object to an activity, Stream stores the unique reference and replaces it at read time. In some complex cases, you need to be able to generate a reference to an existing object and embed that inside of an activity.
If you are using the APIs on web / mobile (see auth section) you must set activity.actor to the reference of the current user or otherwise you will get a permission error (see examples above).
