Users

Create a user

Call this once, after your user has agreed to the terms and tapped Sync Now.

FanFeed creates a profile and returns a user_id. Store that id on your side and send it on every subsequent call. The user_id is the handle, and losing it means losing the link to the user’s synced history.

Email is the only required field.

Idempotent on email, scoped to your partner key: a retry returns the same user_id rather than creating a second profile, and the response marks it with existing: true. The same email under a different FanFeed partner is a different, independent profile; no call made with your key returns data another partner created.

X-PARTNER-API-KEY

string

header

required

Your FanFeed partner API key, issued to your organization.

FanFeed trusts your authentication: the key identifies you, and the user_id in the path identifies which of your users the request is for. FanFeed performs no end-user authentication of its own.

Treat the key as a server-side secret. See the guide for what that implies for the camera-roll ingest path, which is the one call that naturally originates on-device.

Body

application/json

string<email>

required

The only required field.

Example:

"fan@example.com"

partner_user_id

string | null

Your own identifier for this user, stored with the partner-user link so both sides can correlate. Recommended.

Example:

"partner_user_12345"

first_name

string | null

User's first name.

Example:

"Jane"

last_name

string | null

User's last name.

Example:

"Doe"

phone_number

string | null

Stored when it is not already in use by another profile, and silently ignored when it is. Never causes this call to fail.

Example:

"+12125551234"

address

object | null

Optional. Stored with the partner-user link. Not used for matching; matching is driven entirely by photo coordinates.

Show child attributes

Response

User created or returned.

user_id

string<uuid>

required

Store this. Every other endpoint needs it.

Example:

"8f14e45f-ceea-467a-9a1e-2b4d9c3f0a11"

existing

boolean

required

true when this call reused a previously created user record instead of creating a new one.

Example:

false

created_at

string<date-time>

required

Example:

"2026-08-25T18:31:07Z"
