Is there a way to add a workflow transition button to an email?

[David Platt]

In the course of handling an issue, I never want to close an issue before the end user agrees that it is good to be closed. Currently the way that manifests is either

1. automation that closes a ticket after x days with no response (after sending a friendly "this is about to be closed unless you need anything else" email), or

2. I manually email the user to ask if they need anything else, wait for them to reply or if they don't, it automatically closes thanks to the automations I have configured.

What I want is an easy way for users to tell me they're done. I have my customer portal configured to allow them to close a ticket with a transition that's available on the customer portal, but I'd love to have that available as a button in an email to them. 

I can use Jira automation to send html emails and create buttons, but how do I generate the url for transitioning an issue, or otherwise make it so that the user can simply click a "Close this issue" or "I'm done" button in an email?

You can transition a ticket using the API, I'm not sure how you would do that from an email button or link.
