Webhook ETL and programmable gateway, built on the schema you own
Slashbin is a webhook ETL and programmable gateway for developers and the AI agents that work alongside them. You own the Golden Model — one canonical schema per data stream — and every webhook is validated against it, then mapped into the shape each destination needs. Retry, replay, fan-out and the dead-letter queue keep that contract reliable, and the console, the CLI and an agent are three ways to operate the same system.
The Golden Model: the schema you own at the boundary
Each data stream has one Golden Model, and every destination receives the shape it needs from it.
Before
After
One Golden Model per data stream.
What keeps the schema reliable
Retry, replay, fan-out and transformation all operate on data held to that schema.
Data Cleanup & Transformation
Extract, transform, and normalize payloads before they hit your API. Fix bad schemas, rename fields, or compute new values using JSONPath, regex, or custom JavaScript.
Replay
Re-deliver any webhook from the last 30 days with one click. Debug local environments or recover from outages without asking vendors to resend events.
Fan-Out
Route a single webhook to multiple destinations. Filter and split traffic by event type, customer ID, or any value deep inside the JSON payload.
Signature Verification
Native support for Square, Klaviyo, VideoAsk, and Shopify. Plus, a universal signature engine to verify any custom provider without writing a single line of crypto code.
Smart Retries & DLQ
We don't just give up. Configurable exponential backoff retries and a Dead Letter Queue for total failures. Your safety net for when code breaks.
Or drive it all from your terminal
Every operation above is also a command, so an AI agent working on your behalf can set up and run the whole pipeline without a human ever opening the console.
