I have searched for this topic, and I'm quite surprised that I can't seem to find any mention of it.
Essentially, I have an Approval process wherein I'd like to give the Approver three "chances" to Approve or Reject, and take action if it times out. I can manage the loop and timeouts just fine; what I can't streamline is the reminder email.
Instead of a bare-bones email with (at best) a link to the approvers Approvals page in Flow, or (at worst) a new Approval item for each loop, I want the reminder to contain a link to the actual approval item (rather than a link to their Approvals page.) The format of the link is easy to grasp: https://us.flow.microsoft.com/manage/environments/myEnvironmentID/approvals/received/(some GUID)/requests/(some other GUID)
The thing is, I can't find any documentation anywhere that tells me 1) how to get that URL from within the workflow (although I suspect it will have something to do with parsing JSON output); nor 2) what the elements of that URL even mean. All I know is that everything after "/received/" is how to identify the Approval item itself.
The first (some GUID) is the Approval column in the Approval CDS entity. If you get this GUID, you can stop at: https://us.flow.microsoft.com/manage/environments/myEnvironmentID/approvals/received/(some GUID), which will allow the user to get to his/her approval.
I'm still trying to figure out a way to get this GUID without needing a CDS license though.
