As your AI usage grows, its enterprise features—like advanced cost attribution, session tracking, and compliance tooling—become essential for managing complexity, cost, and risk at scale.

How does HookMesh guarantee webhook delivery?

HookMesh guarantees at-least-once delivery through a combination of persistent queues, automatic retries with exponential backoff and jitter for up to 48 hours, and idempotency keys. The idempotency keys ensure that even if a retry is sent, the receiving server can recognize it as a duplicate and not process it twice, preventing side effects while ensuring the payload is delivered.

What is the self-service portal and how do I implement it?

The self-service portal is a fully embeddable UI component you can integrate into your own application's settings or dashboard. It allows your end-users to manage their own webhook endpoints, view delivery logs, and replay failures. Implementation typically involves adding a few lines of JavaScript to your frontend code, which securely loads the portal configured for your specific HookMesh account and customer context.

Can I test webhooks before sending them to live endpoints?

Absolutely. HookMesh provides a Developer Playground within its dashboard. This tool allows you to construct test event payloads, send them through the HookMesh system, and inspect the entire delivery journey—including signature generation and simulated retry logic—without affecting any live customer endpoints. It's perfect for debugging and validating your integration.

What happens if my customer's endpoint is down for an extended period?

HookMesh's intelligent circuit breaker automatically detects endpoints that are consistently failing (e.g., returning 5xx errors or timing out). It will temporarily disable delivery to that endpoint to prevent queue backups. The system continues to retry at increasing intervals. Once the endpoint begins to respond successfully again, HookMesh automatically re-enables delivery and will attempt to send any queued events from the disabled period, subject to your retry policy window.
