What developers should check first

Use cases
OTPs, signups, payment reminders, receipts, bookings, renewals, delivery updates, and feedback requests.
Customer data
Can the API use current customer attributes from your CRM, billing system, payment records, Google Sheets, or Contacts API?

Can the same customer data later support campaigns, surveys, and targeted follow-up?
