Before you can connect your CMS to your MailUp account by filling out the fields on the setup page, you will need to activate the MailUp API in your MailUp account:
Frontend
IP registration for "Frontend" service is required for MailUp integrations with Wordpress, Drupal, Joomla and Blogger
- Log into your MailUp account
- Navigate to Settings > Account settings > Developer's corner > Web services
- Select Frontend from the drop-down
- Check the Enabled checkbox
- For added security, enable IP Address Validation and add the IP address of your Web site (even more than one address)
- Press "Save"
MailUpImport
IP registration for "MailUpImport" service is required for MailUp integrations with Drupal and Joomla
- Log into your MailUp account
- Navigate to Settings > Account settings > Developer's corner > Web services
- If you access to this page for the first time you should also set your password in "WS Password" data field
- Select MailUpImport from the drop-down
- Check the Enabled checkbox
- For added security, enable IP Address Validation and add the IP address of your Web site (even more than one address)
- Press "Save"
How to disable IP address validation
Activation is mandatory, while IP address validation can be disabled for "Frontend" and "MailUpImport".
This choice is unavoidable whenever you cannot be able to determine all the IP addresses from which your application is calling MailUp service (e.g. this issue applies when you use cloud services)
