User Data Endpoint Return Values

The following values may be returned by the User Data Endpoint if the user has given consent and the respective data is available. If a value has no data, it will be returned as 0 or an empty string.

String values are HTML‑encoded (Köln for "Köln") to prevent encoding issues. Characters outside the ASCII range may not be included.

ID Mapping Details

Syntax

professions, disciplines & activities:

{"id":integer,"name":"string","parent_id":integer,"legacy_id":integer}

countries:

{"id":integer,"name":"string","iso":"string"}

Note

• legacy_id corresponds to the historical code used in the legacy lists and helps migrate/map existing data to the new lists (details and examples: Data Mapping & Payload).
• id and parent_id can be identical when a category also acts as a top‑level group (root node). Example (Activities): id=100009 “Practice – owner” with parent_id=100009. In most other cases, top‑level nodes use parent_id=0.
