Note this option requires a developer.
We offer a number of integrations for you to add and request, but if you use an ESP we do not support, you can build your own.
Create a Custom Callback
1) Open the campaign you'd like to manage entries for. Select Integrations and choose Integrate Custom Script.
This can be done in your Brand Settings.
2) Provide a URL in the Callback URL field and we will make a POST to it every 20 minute with whatever entries joined in that period. Test the URL with the Test button.
