API Documentation

Learn about the overall functionality of the MailerCheck API.


You authenticate using a bearer token. This token can be created through the MailerCheck UI by clicking on your profile picture and selecting "API" then click the "Create token" button, give your token a name and that's it.

Remember: Make sure to download or copy your token. You will not be able to see it again after you close the dialog

Authentication header

Once you have your token, you must include it in an authorization header with each request you make to the API.

curl --location --request GET 'https://app.mailercheck.com/api/v1/lists' \
--header 'Authorization: Bearer [your token]'

Your token is tied to the user that created it, and the account to which it was created under. All the endpoints will use this information and return the proper data.
