# Authentication

Making calls to the Akkio API is authenticated via an API Key. You can find your API Key near the bottom of the [Team Settings](https://docs.akkio.com/akkio-docs/settings/team-settings) of the main website.

In order to successfully use endpoints, supply an `X-API-Key` header set to your API Key with all requests.

#### HTTP 401[​](https://api-docs.akkio.com/concepts/authentication#http-401) <a href="#http-401" id="http-401"></a>

A HTTP 401 generally indicates we were unable to successfully authenticate you to the platform as a whole with the provided credentials. Please confirm:

* You have provided an API Key in the `X-API-Key` header
* Your API key is correct
* Your API key is being sent with no leading or trailing spaces

#### HTTP 403[​](https://api-docs.akkio.com/concepts/authentication#http-403) <a href="#http-403" id="http-403"></a>

A HTTP 403 generally indicates that you are trying to access a resource that the organization linked to your API Key does not have access to. Please ensure you are using the API key of an organization that has access to the resource in question.

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.akkio.com/akkio-docs/concepts/authentication.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
