Hi @JAWis,
Welcome to the Community.
Suppose you're trying to integrate Constant Contact email open data into Google Sheets using Zapier, but are not seeing the expected 'response' data. In that case, it may be due to trigger setup issues, API limitations, or integration settings. Ensure you've selected the right trigger, tested it for available fields, and verified your Constant Contact connection. If the data still doesn't appear, consult the documentation or contact Zapier Support. You can export the data from Constant Contact manually and import it into Google Sheets as a backup.
This will help you get closer to resolving the issue. If you have any more questions or need further assistance, please feel free to ask. We're here to help.
Hey @JAWis 
Were you able to get this sorted? If not, can you share a screenshot showing an example of the response value (in Constant Contact) that’s missing? Be sure to blur/remove any personal info like names, emails, addresses etc. from the screenshot first (you can use a tool like Zappy for that).
I checked the API Documentation for Constant Contact and it doesn’t look like there’s a “response” field included with their Get an Email Opens Report endpoint:

So it could be that an additional action is needed to obtain the response value
but would need to know exactly where that “response” is stored to be able to advise on that.
Also, in your screenshot it looks as though the Create Spreadsheet action would create a spreadsheet each time an email is opened, with the column names set as the values passed from the Constant Contact trigger. Is that the intention here, or were you wanting a new row to be added to an existing spreadsheet instead? If it’s the latter, I’d suggest using the Create Spreadsheet Row (Google Sheets) action instead.
Looking forward to hearing from you!
