What’s an API key and how can I get mine?

You can use our API to connect your website or information system with Sendinblue. This will enable you to automatically trigger certain actions. You can use our API to automatically add new contacts as well as do more complex tasks, such as:

  • create and schedule campaigns from the API
  • export users belonging to particular lists
  • export campaign statistics
  • etc.

Finding your API key

While logged into your account, click on your name at the top right, then on SMTP & API or visit this page while logged into your account: https://account.sendinblue.com/advanced/api.


Under the API keys tab, you will find two API keys: one for each version of the API

  • API v2. To learn more about API v2, click here.save image

We recommend using API v3 for your custom integrations as it is the newest and most powerful version.
