You have Zapier integration which is basically the same, but we would rather use Microsoft flow... it cant be that hard once you have one to do another. Basically just requires you to apply and with your existing rest api's the rest will be fairly easy.
Thank you for the request. You should know that the Aha! REST API is available and this is actually what we leverage when building in-house integrations.
At this time, we do not have near-term plans to build this specific integration based on current priorities and the level of customer feedback on this idea. However, we would encourage you to use the API to build a custom application for your organization's use.
