# Brevo authentication

> To be able to create a connection, you require a Brevo **API Key**. Consult the [official Brevo documentation](https://developers.brevo.com/docs/how-it-works#requests) to find out how to retrieve an API Key.

## Prerequisites

To be able to create a connection, you require a Brevo **API Key**. Consult the [official Brevo documentation](https://developers.brevo.com/docs/how-it-works#requests) to find out how to retrieve an API Key.

## Add the Brevo connection

1. In Integration Service, select the Brevo connector and select **Connect to Brevo**.
2. Insert the **API Key** for your Brevo instance and select **Connect.**

   For any secret-type field, you can select the menu next to the field and choose **Use credential asset** to reference an Orchestrator credential asset linked to an external vault instead of entering the value directly.
