Can you clarify for me please what it is you are trying to add/build out on this URL that is not working? Is it a referral link, affiliate link, link to special offer?
It is for capturing campaign details running through various mediums such as emailers, google campaigns, facebook campaigns etc. We are capturing the utm source and utm medium received from the url.
Were you ever able to fix this issue? I am having a similar problem where i cannot add params to the url ex: “?state=abc123” without getting the following error “Something went wrong! Please refresh and try again.”
