GMJ Roaming API v2 (Alpha)

Alpha: not for production. v2 can change at any time without notice, including field names, response shapes and endpoints. Build production integrations on v1.

v2 is a cleaner contract we're working on:

• Prices are whole IDR amounts with an explicit currency.
• eSIMs are referenced by a stable esimId instead of ICCID + transaction pairs.
• Responses are { "data": ... } with camelCase fields. Errors are { "message", "errors"? }.
• Purchases are idempotent: retrying with the same transaction_id and body replays the original result.
