API key authentication
Generate and use an API key to authenticate your Brevo API requests
API keys authenticate your requests to the Brevo API. Generate an API key from your account settings and include it in the api-key header for each request.
You need a Brevo account. Sign up if you don’t have one yet.
Enter a descriptive name for your API key (e.g., “Production API”, “Development API”).
Copy the API key immediately and store it securely. You can’t view it again after closing the dialog.
Store your API key securely. If you lose it, generate a new one. Treat API keys like passwords — never commit them to version control or share them publicly.
To use your API key in the developer portal playground, whitelist your current IP address. See IP security for instructions.
Include your API key in the api-key header for all API requests. The endpoint below validates your API key and returns your account details.
Your API key identifies your account and authorizes API access. Include it in every request to authenticate your calls.
