Update User Profile

Update specific fields of an existing user profile without changing everything.

The userId in the URL path should be your externalUserId. Only the fields you include in your request will be updated—everything else stays the same. Perfect for targeted updates like changing an email address or adding new properties.

Prefer a simpler approach? Use POST /users instead—it automatically creates or updates the user, so you don't need to know if they exist yet.

Optionally associate the user with an organization by providing an externalOrganizationId. If the organization doesn't exist yet, we'll create it automatically.
