Get user

Returns a single user by its ID.

Path Parameters
subKey string — REQUIRED

Subscribe key identifying the keyset.

userId string — REQUIRED

ID of the user.

Query Parameters
auth string

Required unless you supply signature instead. An Access Manager token authorizing the operation. Use this for client-side callers.

Supply either auth or signature, never both. Supplying neither returns 401 (DS-0203). Supplying both returns 403 (DS-0201).

If the token cannot be decoded, or its projection does not permit the requested fields, the request fails with 403 (DS-0202, INVALID_TOKEN).

signature string

Required unless you supply auth instead. A signature proving the request was signed with the secret key for this keyset. Use this for server-side callers.

Supply either signature or auth, never both. Supplying neither returns 401 (DS-0203). Supplying both returns 403 (DS-0201).

Refer to Signature generation for how to compute it.

message string

A human-readable description of the error, intended for logs and diagnostics. Not stable across releases - do not parse or branch on it.

path string — OPTIONAL

Location of the input that caused the error. Present only for codes that can identify one. The form depends on the code: a JSON Pointer into the request payload (DS-0008, DS-0602, DS-0650), a query parameter name (filter for DS-0005, sort for DS-0006), a field name (DS-0004), or a class property name (DS-0903).

INTERNAL_SERVER_ERROR

errorCode string

A machine-readable error code. Stable across releases - use this, not message, for programmatic branching. The HTTP status for a given code is fixed.

Codes are grouped by range. Not every code can occur on every operation; each response documents the subset it can return.

* required
subKey*
Type: string
Subscribe key identifying the keyset.
userId*
Type: string
ID of the user.
auth
Type: string
Required unless you supply signature instead. An Access Manager token authorizing the operation. Use this for client-side callers.

Supply either auth or signature, never both. Supplying neither returns 401 (DS-0203). Supplying both returns 403 (DS-0201).

If the token cannot be decoded, or its projection does not permit the requested fields, the request fails with 403 (DS-0202, INVALID_TOKEN).
signature
Type: string
Required unless you supply auth instead. A signature proving the request was signed with the secret key for this keyset. Use this for server-side callers.

Supply either signature or auth, never both. Supplying neither returns 401 (DS-0203). Supplying both returns 403 (DS-0201).

Refer to Signature generation for how to compute it.
