Manage API keys

API keys are secret tokens used to authenticate your requests. They are unique to your account and must 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.

You can view and manage your API keys from the API keys Dashboard page. You can also manage your API keys programmatically using the API or the Resend CLI:

• Create a new API key with a name, permission, and optional domain restriction
• List all API keys in your account
• Update an API key's name (other properties can only be edited in the Dashboard)
• Delete an API key

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.

After creating an API key, you can edit the following details:

• Name
• Permission
• Domain

To edit an API key in the Resend Dashboard, click the More options button and then Edit API key.

You can also rename an API key programmatically using the Update API key endpoint. The API only updates the key's name, while permission and domain can only be edited in the Dashboard.

If an API key hasn't been used in the last 30 days, consider deleting it to keep your account secure.

You can delete an API key by clicking the More options button and then Remove API key.

When visualizing an active API key, you can see the total number of requests made to the key. For more detailed logging information, select the underlined number of requests to view all logs for that API key.
