Appstrate
[Developer Platform]

Webhooks that deliver. And retry. And stay signed.

Standard Webhooks spec. HMAC-SHA256 signed. BullMQ-backed delivery with 8-attempt exponential retry.

[01 · Why it matters]

Your webhook handler fails once. Does your platform even notice?

Webhooks without retries are a single point of failure. Webhooks without signing are a security hole. Webhooks without a delivery log are a debugging nightmare.

Appstrate ships the full Standard Webhooks spec: HMAC signing, exponential backoff, full delivery history, per-app scoping, secret rotation.


[02 · How it works]

Subscribe. Sign. Retry. Log.

Create a webhook, receive signed events, failures retry 8 times over ~24h, every delivery is queryable.

In practice

Every piece of Appstrate is a declared, versioned artifact — the agent, its tools, its skills, its provider connections. You describe them once; the platform handles packaging, dependencies, isolation, and execution.

Each section below goes deeper on what that means for webhooks that deliver. and retry. and stay signed.
