The Control Plane forInbound Webhooks
Replace custom webhook ingestion logic with a managed control plane. Flow validates, filters, transforms, and routes events to the right destinations — eliminating brittle glue code and custom pipelines.
Replace Custom Webhook Infrastructure
Stop building and maintaining custom webhook ingestion logic
Receive Webhooks Without Custom Infrastructure
Create webhook endpoints instantly — no servers to provision, no load balancers to configure.
Transform Payloads Without Brittle Glue Code
Modify, enrich, or restructure webhook data on-the-fly with JavaScript — no custom middleware needed.
Route Events Without Complex Logic
Filter and route webhooks based on content, headers, or custom rules — eliminating ad-hoc routing code.
Fan-Out Events Reliably
Forward webhooks to multiple destinations simultaneously with independent delivery tracking — no custom queues required.
Test Webhooks Locally Without Exposing Your Server
Test local webhooks by tunneling them directly to your localhost development environment with our CLI. Receive webhooks on your local machine securely — no ngrok, no public endpoints, no security risks. Perfect for local webhook testing during development.
Debug Webhook Issues in Minutes
Monitor requests in real-time with full payload and header inspection — reducing debugging time from hours to minutes.
Manage Endpoints Effortlessly
Create and manage webhook endpoints with a clean, intuitive interface. View all your endpoints, their status, and activity at a glance.
- Instant endpoint creation with custom URLs
- Monitor request counts and activity
- Test webhooks locally with CLI localhost tunneling
Real-Time Request Monitoring
See every webhook request as it arrives. Inspect payloads, headers, and responses in real-time with our powerful monitoring interface.
- Live request feed with timestamps
- Detailed payload and header inspection
- Filter and search through request history
Powerful Relay Rules
Configure sophisticated relay rules with filtering and transformation. Route webhooks to the right destinations with precision.
- Content-based filtering and routing
- JavaScript transformation engine
- Multi-destination fan-out
Frequently Asked Questions
Everything you need to know about Flow
How do I test webhooks locally with Flow?
Create a Flow endpoint, then use the hookVM CLI to forward webhooks to your localhost. Run hookvm flow listen --endpoint-id your-id --port 3000 to tunnel webhooks directly to your local development server without exposing it to the internet. This is perfect for local webhook testing during development.
Can I transform webhook payloads before forwarding them?
Yes, Flow includes a JavaScript transformation engine that lets you modify, enrich, or restructure webhook data on-the-fly. You can add custom headers, filter fields, or completely transform the payload structure without writing custom middleware.
How does Flow handle webhook routing?
Flow allows you to configure sophisticated relay rules with content-based filtering. You can route webhooks to different destinations based on payload content, headers, or custom conditions. Flow also supports fan-out to multiple destinations simultaneously.
Is Flow better than building custom webhook infrastructure?
Flow eliminates the need to build and maintain custom webhook ingestion logic, load balancers, routing code, and transformation middleware. It provides instant endpoints, real-time monitoring, localhost tunneling, and reliable delivery out of the box, saving weeks of development time.
