# Authentication

There are two methods for making an authenticated request to the Immuta API. Select a tab below for instructions.

{% tabs %}
{% tab title="API key method" %}

1. Generate your API key on the **API Keys** tab on your profile page and save the API key somewhere secure.
2. You will pass this API key in the authorization header when you make a request, as illustrated in the example below:

   ```bash
   curl \
       --request GET \
       --header "Content-Type: application/json" \
       --header "Authorization: 846e9e43c86a4ct1be14290d95127d13f" \
       https://your-immuta-url.immuta.com/data/connection/123456789
   ```

{% endtab %}

{% tab title="Bearer token method" %}

1. Generate your API key on the **API Keys** tab on your profile page and save the API key somewhere secure.
2. Pass this API key in the authorization header and make the following request to the `authentication` endpoint:

   ```bash
   curl \
       --request POST \
       --header "Content-Type: application/json" \
       https://your-immuta-url.immuta.com/bim/apikey/authenticate \
       -d '{ "apikey": "YOUR_API_KEY" }'
   ```
3. You will receive a response that includes your bearer token. Pass that bearer token in the authorization header when you make a request, as illustrated in the example below:

   ```bash
   curl \
       --request GET \
       --header "Content-Type: application/json" \
       --header "Authorization: Bearer dea464c07bd07300095caa8" \
       https://demo.immuta.com/data/connection/123456789
   ```
