Secure access
Every integration uses an authorized live or test key. Secret values are displayed only when created and should be stored securely by the client.
Developer connectivity
Connect your website to SIMHSYCN through a controlled API.
Submit transactions, check status, discover services, monitor requests, and receive signed result notifications.
Transaction endpoints
Dedicated endpoints support configured airtime, data, cable, electricity, balance checks, transaction status, and timeline information.
Signed result delivery
Webhook events include a delivery identifier, event name, timestamp, and HMAC signature so client websites can verify the raw payload before updating a transaction.
Customer developer center
Approved customers can inspect key status, API request activity, webhook readiness, recent response codes, and integration documentation from their own portal.
