# Troubleshooting

If you're having trouble accessing the Select Star API, please check the list of possible issues below. Also feel free to contact us in our [community Slack channel](https://selectstarcommunity.slack.com).

### Unauthorized access

If your request receives a `401 Unauthorized` error, please check:

* you've created an API token and are sending it in the header of the request.
* you're using `Token` in the authorization header, and not `Bearer`.

Please also check [API Token](/select-star-api/authentication.md) for more details of the authorization process.

### Passing API Parameters

When passing API parameters for a POST or PATCH request, using `params` for the request body may lead to unexpected results. For POST and PATCH requests, it is recommended to use `data` instead of `params` to ensure correct handling of the request body.
