# Authentication

d6 Integrate requires authentication via username and password credentials which are provided to you by d6 after successful completion of a data sharing license agreement.

The credentials must be passed in the request header using the following parameters:

> HTTP-X-USERNAME
>
> HTTP-X-PASSWORD

{% hint style="warning" %}
All API requests must be made over HTTPS. Requests made over plain HTTP will fail and may risk exposing your key. Your credentials must never be shared. Do not use your credentials in client side code as you may risk exposing it to third parties.
{% endhint %}
