Developer FAQ

Questions you probably have

Straight answers. No sales-deck theatre.

OAuth 2.0 Client Credentials via OmaxTelecom ID. You exchange a client_id and client_secret for an access token, then send Authorization: Bearer <token> on every request to the Bappy API.
Create and manage Links (active eSIM or physical SIM subscriptions), fetch compatible top-up plans, send SMS to a Link, check live network status, browse plans and coverage, manage wallet balance, and pull transaction analytics. Every Link returns ICCID, LPA profile, and Apple/Android activation URLs.
Both. The same POST /v1/links endpoint handles eSIM (returns LPA + activation URLs) and physical SIM provisioning. One integration covers both.
Wallet-based. Your organization holds a prepaid balance. Each Link creation and top-up debits the wallet at the plan price. If provisioning fails on the provider side, the amount is auto-refunded to your wallet.
Six regions: Europe, Africa, Asia, Latin America, North America, and Oceania — with 210+ countries and regional bundles available. Query GET /v1/plans or GET /v1/plans/regions for the live catalogue.
