# Authenticate and call your first API

This article describes how to authenticate and call your first API.

After [generating an API key](https://docs.prismacloud.io/en/enterprise-edition/content-collections/data-security-posture-management/api-documentation/create-an-api-key), you're ready to authenticate and make your first API call!

1. For authentication, ensure you include your Prisma Cloud DSPM API key in the headers using the following format: **dig-api-key':'YOUR\_KEY'**
2. To perform a test, attempt to call the specified endpoint with filters. This action should display a list of the initial 20 S3 buckets in your environment: [**https://api.dig.security/v1/assets**](https://api.dig.security/v1/assets)

**NOTE**: Make sure you call the API with **https\://** and not **http\://**

Servers:

* EU stacks = <https://api.dig.security>
* US stacks = <https://api.use1.dig.security>

For further information, refer to the [API endpoints documentation](https://pan.dev/prisma-cloud/api/dspm/get-started/).

## 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.prismacloud.io/content-collections/data-security-posture-management/api-documentation/authenticate-and-call-your-first-api.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.
