What is an API Key

API Keys are secret tokens used to authenticate your requests. They are unique to your account and should be kept confidential. You can use multiple keys to isolate different application actions to different API Keys. This allows you to view logs per key, detect possible abuse, and control any damage that may be done accidentally or maliciously.

​
API key management

You can view and manage your API keys from the API Key Dashboard. You can also create, list, or delete your API keys using the API, or the Resend CLI.

​
View all API Keys

The API Dashboard shows you all the API Keys you have created along with their details, including the last time you used an API Key. Different color indicators let you quickly scan and detect which API Keys are being used and which are not. View All API Keys
