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. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.selectstar.com/select-star-api/troubleshooting.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
