# Why does the Python client lack reference\_id lookup?

The Python client doesn't currently expose lookup by `reference_id`. Two options:

* **Call the REST endpoint directly** (`userInfo` supports lookup by `reference_id`).
* Open a pull request on the open-source client, which the team is happy to merge.
