Authenticating with the API

Authenticating Requests

Authenticating with the MailPace API is simple and easy to do with all HTTP libraries, all you need to do is provide a single header in your HTTP POST request, called MailPace-Server-Token containing your API token

API Tokens

API tokens can be found under the "API Tokens" menu of a each Domain, there is one unique API token for every domain

Your API token is a string which provides access to send emails from your domain. Anyone with this token can send emails on your behalf, so please keep it a secret to prevent abuse. For web applications you should use environment variables or appropriate secret management software, such as Hashicorp's Vault.

If you suspect that your API token has been leaked or stolen, please contact us so we can regenerate a token for you


Replace TOKEN_GOES_HERE with your token:

curl "" \
-H "Accept: application/json" \
-H "Content-Type: application/json" \
-H "MailPace-Server-Token: TOKEN_GOES_HERE"
