@Brian Clayton,
The only way you're going to be able to call into Blue Prism via a REST interface will be with a REST-to-SOAP gateway in the mix. There are lots of options in this area.
Alternatively, Microsoft has a REST interface called Graph. This is their super REST API that supports multiple applications including Teams. You could build a process that polls Teams Channels, using Graph, looking for the specific mentions and then puts the request on a work queue. Then another process can handle executing the processes from the work queue.
It's not a great solution, but if you can't leverage a gateway it's probably the only other option.
Cheers,
