# Flickr User Groups API

The groups one person belongs to, with their role and counts.

`GET /v1/flickr/users/{userId}/groups` returns `data.groups`, a single list of the groups the person belongs to. Each row carries `id`, `name`, `isAdmin`, `memberCount`, `poolCount`, `isEighteenPlus`, `invitationOnly` and `iconUrl`; `coverPhotoUrl` is always null for this list.

This route returns the whole public list in one response rather than a paged collection. A person with no public groups returns `lookupStatus: found` with an empty list; an unknown person returns `not_found`.

## FAQ

### Does it page?

No. The whole public group list is returned in one response. Use the group route for details on each group.

### What does isAdmin mean?

Whether the person is an admin of that group.

### Is there a cover image?

No. coverPhotoUrl is always null for this list; use the group route for the group icon and cover.

### How much does the group list cost?

Pricing is documented on the operation in the API registry (shown on this page). Confirm on every response with meta.creditsCharged: that field is the billing source of truth.

### Are private groups included?

Only groups in the public list. A fully private membership is not listed.
