# Storing your credentials

Your credentials should all be treated as sensitive information as they allow access to your learning data, which includes personally identifiable information. That means that for security reasons, rather than including the credentials in your application code, it is better to store them securely (such as environment variables).

This reduces the risk of the credentials accidentally being viewed by someone else or checked into an online code repository.

```
AWS_BUCKET=data-connector-v2-123456-production 
AWS_ACCESS_KEY_ID="XGTWTIPVHZXSOZFGDOAL" 
AWS_SECRET_ACCESS_KEY="UbCtK9sUDmWXB5/cRDwwckoB6PYGhE/vIdkhg3oV"
AWS_DEFAULT_REGION=us-east-1
```

# 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://enterprise-docs.datacamp.com/integrating-our-data-into-your-tools-via-data-connector-2.0/getting-started-with-data-connector-2.0/storing-your-credentials.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.
