Build an online prescription (e-prescription) integration using Provet Cloud's eprescription API

Steps

1. Add a custom integration button in Settings > Integrations > Custom integration buttons, scoped to the Client, Patient, or Consultation page as appropriate
2. POST to /api/0.1/eprescription/prescription/ with client_id, department_id, prescriber_id, issue_time, and a prescription_items array (name, patients, strength, instructions, quantity_packages, valid_until)
3. Leave status unset to default to Draft (1), or set it explicitly using Provet's documented status constants (Sending=2, Sent=3, Accepted=4, Rejected=5, Canceled=6, Error=7, Accepted with warning=8)
4. Update only remarks and status via PATCH /api/0.1/eprescription/prescription/<id>/ as the prescription moves through your pharmacy workflow
5. Fetch department-level e-prescription settings via GET /api/0.1/department/<department_id>/settings/, and optionally watch the Department settings webhook for configuration changes
6. To collect the prescription fee, create a separate counter sale referencing the fee item from settings, add it, finalize it, and record payment
