To connect your GetResponse account to Spotlightr it is necessary to find your GetResponse API key and copy it into the corresponding field in Spotlightr. Here are the steps:
Get Response API key is located in your GetResponse account.
Go to Tools >> Integrations & API and open the API tab.
Generate and Copy the key:
Log in to Spotlightr, go to App Settings >> Integrations >> Add Integration.
Click on GetResponse, this will open up a pop-up (pop-ups should be allowed in your browser).
Add a title, paste your API key into the corresponding field and click on the button Create.
*** Important note is that Spotlightr integration selects your GetResponse Forms, NOT LISTS.
