Difference between sf_nonteam_add_members , sf_nonteam_join & sf_nonteam_claim_membership

Info V.1,

Doing a little more digging into this, if you refer to our v1 docs for the get_events endpoint there is an entry under the notes section that states:

• The events sf_team_mount and sf_nonteam_mount will eventually replace sf_team_join and sf_nonteam_join.

I'm thinking this is why you're not seeing the sf_nonteam_join events when a non-team member joins/mounts shared content.

I do want to reiterate that these event types are all v1 and that migration to v2 is highly recommended. The following content can help with that process:

For a brief description of what actions cause what events see the event types section of the v1 documentation:
https://www.dropbox.com/developers-v1/business/docs#log-get-events

The events migration guide referenced above shows the mapping of v1 categories to v2 categories.

I hope this gives you the information you are looking for. Thanks!
