Hey @mzuzelka! As promised, we’ve just released a set of new APIs that will allow you to connect your coffee machine to Fabman.
Just create a bridge API key for the coffee machine and use it to POST the keycard to the new /access endpoint. It will check whether they are allowed to make coffee and return the Member ID and other details, if the are.
Check the bridge API documentation for more information and let me know if you have any questions.
