Attempting to migrate Constant Contact data to Klaviyo using the Integration tool and wondering if anyone has cracked this code recently, and can share steps on creating the API keys on the Constant Contact side of things? Keep running into error messages.
I have followed the instructions provided from Klaviyo to the T, but keep running into the same error message. Have chatted with support for a few hours, no luck…
For what its worth, I did notice the instructions from Klaviyo may be outdated… They mention a V2 API generator from Mastery that Constant Contact uses to create API’s, however it appears that Constant Contact now uses a V3 API generator, with different screens and set up process. Not sure if this is the issue?
Creating the API keys on the Constant Contact side of the house isn’t the smoothest, which Im sure isnt helping.
Any and all help welcome.
