Configuring Threshold Webhook Alerts for Wallet Floors

Learn how to configure automated balance threshold webhooks in IOSOR to monitor prepaid accounts, prevent service interruptions, and manage JIT number provisioning effectively.

Configuring Threshold Webhook Alerts for Wallet Floors.

Understanding Prepaid Wallet Thresholds

In the IOSOR ecosystem, maintaining continuous service for high-volume messaging and voice traffic requires proactive balance management. When your prepaid account reaches a USD 20 balance floor, the platform triggers an automated webhook event. This mechanism allows your backend systems to ingest real-time financial telemetry, ensuring that your JIT number provisioning remains uninterrupted. By monitoring these events, you avoid sudden service halts that could impact your end-user OTP or DLR delivery pipelines.

Configuring Webhook Endpoints

Navigate to the IOSOR Developer Console to define your notification endpoint. You must provide a secure HTTPS URL capable of handling POST requests. Once configured, the platform will dispatch a JSON payload containing your current ledger balance, currency, and the specific threshold trigger event. Ensure your endpoint implements signature verification to validate the authenticity of the incoming data, protecting your infrastructure from unauthorized callback attempts.

Managing Prepaid Holds and JIT Provisioning

When your balance dips below the defined threshold, IOSOR may initiate a prepaid hold on new resource requests. This JIT approach ensures that you do not over-consume credits beyond your available liquidity. If your monthly spend approaches the USD 1,000/month mark, we recommend reviewing your auto-top-up settings to maintain consistent throughput. This prevents the system from rejecting new E.164 number assignments or blocking outbound SMS traffic during peak operational hours.

Handling Balance Recovery Events

Once your account is topped up, the system automatically clears the hold status. Your webhook listener should be designed to parse the 'status_cleared' event, which signals that your account is ready for new provisioning tasks. This automated handshake ensures that your platform remains responsive to market demand without manual intervention. Always log these state transitions to maintain a clear audit trail of your financial health within the IOSOR environment.

Related Documentation and Best Practices

To ensure proven integration, review the following technical guides. These resources cover log management, duplicate prevention, and transactional integrity for your balance operations:

Start with IOSOR

Navigate to the IOSOR Developer Console to configure your HTTPS POST endpoint under the Webhook Alert settings. Ensure your server is set to process the USD 20 threshold trigger and automatically route top-up requests to your payment backend. Validate the webhook signature and response handshakes in the console sandbox prior to enabling live prepaid hold automations.

IOSOR takeaway

Automating webhook alerts for the USD 20 balance floor protects high-volume messaging pipelines from unexpected service holds and API rejections. Event-driven notifications ensure your system reacts immediately to dwindling liquidity before resource gates are enforced.

Do configure your listener to clear balance holds automatically upon receiving the status_cleared payload after a top-up. Don't rely on periodic REST polling to monitor wallet balances, as delayed requests risk hitting hard consumption caps during sudden traffic spikes.
