How it works
A Mutualser EPS member writes to or calls your organization.
Arbol answers and asks for the Mutualser EPS order and authorization before offering a slot.
The appointment's payment or charge is recorded in FreshBooks.
Your team reconciles from FreshBooks, with every payment next to its appointment.

Questions
Do we need to build on the FreshBooks API?
No. Arbol connects with FreshBooks: your team turns it on from Arbol with your organization's account and approves what goes in.
Does the money go through Arbol?
No. The payment happens in FreshBooks, into your organization's account. Arbol sends the link and records the conversation.
What happens to patient data?
They are health data, sensitive under Colombia's Law 1581 of 2012: processed for a stated purpose, with the patient's authorization and with encryption and isolation per organization. Every conversation is recorded and exportable.
