Telgoo5 exposes 100+ REST APIs covering customer creation, plan/top-up/wallet purchase, port-in submission and validation, SIM swap, eSIM allocation, agent login, balance inquiry, account status, inventory, and reporting. The API Log under the APIs module records every request and response for the last 30 days, which is invaluable when debugging an integration.

Common API sequences for a prepaid program:

• create_customer_prepaid → assign_sim (or assign_esim) → activate_customer → return MDN.
• create_customer_prepaid_multiline (with is_esim=Y) → eSIM allocated automatically → ESIM QR Code 4G notification fires.
• submit_portin_order → query_portin → get_portin_order_information → update_portin (if customer corrects info) → port completes, Port Activated notification fires.
• change_plan, add_topup, add_wallet — all callable from your CRM or website.

If you need OAuth scopes, sample payloads, or a Postman collection, ask Partner Success or open a ticket — the full API spec is published in the support portal under Telgoo5 APIs.
