Thanks for the details. A few common causes in GoodData Cloud can lead to “user not found” right after a create call: 1) Wrong API or base URL - Make sure you’re calling your GoodData Cloud domain (e.g.,
https://your-org.cloud.gooddata.com), not
gooddata.com or a trial/prod mismatch. Using the public site or the wrong hostname returns 404s or HTML responses and won’t create users. [[Users API host](

GoodData.CN internal IdP and are not available in Cloud. [[Cloud endpoint](

https://www.gooddata.com/docs/cloud/manage-organization/manage-users/)] 3) Organization uses GoodData’s hosted IdP (managed OIDC) - If your org still authenticates via GoodData’s hosted IdP, creating a user only via /entities/users is not enough to let them log in; the account must also exist in the hosted IdP, which you cannot create yourself. In this state, login or “get user info” checks can fail with “user not found.” The workaround is to have GoodData Support provision the user in the hosted IdP, or switch to your own OIDC and manage users end‑to‑end. [[Managed OIDC limitation](

If this is wrong or reused for multiple users, authentication and lookups may fail. [[Create user requirements](
https://www.gooddata.com/docs/cloud/manage-organization/manage-users/)] 5) Referencing a non-existent userId immediately after a failed create - A 404 “not found” on GET/PUT often means the userId didn’t exist (typo, wrong org, or the create actually failed). Double‑check the POST response status and body; then GET the user to confirm existence. [[404 due to wrong userId](

It should be 201 with the created resource. Use: POST /api/v1/entities/users on your org hostname with Content-Type: application/vnd.gooddata.api+json. [[Cloud endpoint](

https://www.gooddata.com/docs/cloud/manage-organization/manage-users/)] - Immediately GET the new user to confirm it exists: GET /api/v1/entities/users/b44767e0-532f-4786-b729-c97409f89329?include=userGroups. [[Entity interface tip](

If hosted IdP, you’ll need Support to provision the identity; if your own OIDC, ensure authenticationId matches the user’s sub claim in your IdP. [[Managed OIDC limitation](
