I’m not sure how easy it would be to work with the RTM API, it looks like it’s an XML-format API that is a bit antiquated and less Javascript-friendly…but it is likely possible.
I don’t recall their app playing nice with common integration methods locally, like URL schemes and Shortcuts, but it’s been a while since I’ve looked at it.
Sending an email is pretty straight-forward. You should be able to set that up with much trouble. Get started with the Mail integration guide. Mail actions can be configured with values like recipients ahead of time. From the RTM docs, you should be able to get your email from RTM settings, then you either send the text of the task in the subject line, and anything in the body of the email will become notes. That would look like an action in Drafts with a single “Mail” action step, configured something like:
- To: your-rtm-email@rememberthemilk.com
- Subject: [[title]]
- Body: [[body]]
That would put the first line of the draft as a task, and any remaining text as notes. I would test it with “Send in Background” off and make sure it’s all working the way you like, then turn it one once you are happy it’s working turn that on so you won’t need to have the mail window popup each time.
