Scopes

In a typical sign-in scenario, the third party redirects the user to the sign-in form in order to obtain their identity information. The third party needs to supply its own identification (client_id) as well as the list of user data it is interested in. This is what the scope query string parameter is for. It contains one or more keywords (comma-separated); the user can then decide whether to share the relevant data.

The list of accepted scopes defines the amount of information returned by the following /api/v1/user call.

identity

The identity scope is mandatory and must be accepted by the user. It results in the following items being included in the response to /api/v1/user:

• oauth_user_id is a unique persistent user account identifier
• username is the part of the e-mail address before the @-sign
• domain is the part of the e-mail address after the @-sign
• firstname is the given name (when available)
• lastname is the family name (when available)
• advert_user_id is a user account identifier suitable for usage within the Seznam ad infrastructure

contact-phone

Requesting the contact-phone scope adds the user's contact phone number to the result of the /api/v1/user call:

• contact_phone (only when provided and validated by the user; null otherwise)

avatar

Requesting the avatar scope adds the user's profile picture to the result of the /api/v1/user call:

• avatar_url – the image's URL

A reasonable URL will be provided for all users, including those without an image – a default auto-generated picture with initials (SVG) will be returned in this case. Picture dimensions (square) can be specified by appending the size after a slash, e.g. ${avatar_url}/64.

adulthood

Requesting the adulthood scope adds the user's adulthood information to the result of the /api/v1/user call:

• adulthood – true/false value corresponding to the user's adult status

The true value is present for users with a correctly set and verified birth date, at least 18 years old.
The false value is present for users without a birth date set, unverified or younger than 18 years.
Providing the adulthood information cannot be rejected by the user; it is therefore reasonable to only request the given scope if you really depend on the information.
