The Webhook Gateway for Serious Engineering
Slashbin is a Webhook ETL and Programmable Gateway for developers.
Stop writing boilerplate. Slashbin handles webhook ingestion, transformation, filtering, and replay—so you can focus on your actual product.
Built for Real Problems
Every feature exists because engineers needed it in production.
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.
Golden Model Validation
Stop bad data at the door. Enforce strict JSON schemas on incoming traffic. If a vendor silently changes a field type (e.g., string to int), we catch it before it crashes your backend.
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.
"Slashbin saved us 40 hours of webhook debugging. The replay feature alone paid for itself."
