## Authentication

Requires one of the following:

- `apiKey`, http, header `Authorization`, scopes: `roles:write`
- `oauth2`, oauth2, scopes: `roles:write`

## Header parameters

- `assignPlatformAuthorizationRole.header.Idempotency-Key` (string, required) — A caller-chosen key making this request safe to retry. A replay of a completed request returns the recorded response with `Idempotency-Replayed: true`. Reusing a key for a different request is refused.
  - maxLength 255
- `assignPlatformAuthorizationRole.header.Quire-Version` (string, optional) — The dated API revision to serve this request at. Omitted, the request is served at the revision the credential was issued against. The response echoes the revision actually applied.
  - format `date`

## Request body

- `assignPlatformAuthorizationRole.user_id` (string, required)
  - format `uuid`; pattern `^([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-8][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}|00000000-0000-0000-0000-000000000000|ffffffff-ffff-ffff-ffff-ffffffffffff)$`
