This is designed to allow for a PlayFab ID lookup of any arbitrary service identifier a title wants to add. This identifier should never be used as authentication credentials, as the intent is that it is easily accessible by other players. ## Error codes This operation may return the following PlayFab errors: | Error | Code | | --- | --- | | IdentifierAlreadyClaimed | 1238 | | UserisNotValid | 1030 | ## OpenAPI ````yaml /services/playfab/api-references/rest/server/server.openapi.json post /Server/AddGenericID openapi: 3.0.0 info: version: '260922' title: PlayFab Server API description: >- Provides functionality to allow external (developer-controlled) servers to interact with user inventories and data in a trusted manner, and to handle matchmaking and client connection orchestration termsOfService: https://playfab.com/terms/ contact: url: https://community.playfab.com/index.html license: name: Apache 2.0 url: https://github.com/PlayFab/API_Specs/blob/master/LICENSE servers: - url: https://{titleId}.playfabapi.com description: PlayFab title endpoint variables: titleId: default: your_title_id description: Your PlayFab title ID (hex). security: [] tags: - name: Account Management description: Account Management APIs - name: Analytics description: Analytics APIs - name: Authentication description: Authentication APIs - name: Character Data description: Character Data APIs - name: Characters description: Characters APIs - name: Content description: Content Service APIs - name: Friend List Management description: Friend List Management APIs - name: Matchmaking description: Matchmaking APIs - name: Platform Specific Methods description: Platform Specific Methods APIs - name: Player Data Management description: Player Data Management APIs - name: Player Item Management description: Player Item Management APIs - name: PlayStream description: PlayStream Management APIs - name: Server-Side Cloud Script description: Server-Side Cloud Script APIs - name: Shared Group Data description: Shared Group Data APIs - name: Title-Wide Data Management description: Title-Wide Data Management APIs paths: /Server/AddGenericID: post: tags: - Account Management summary: Add Generic ID description: > Adds the specified generic service identifier to the player's PlayFab account.
