Question 1

How do I expose webhook tester to the internet for testing with GitHub?

Accepted Answer

Use the built-in ngrok tunneling by setting --tunnel-driver=ngrok and providing an auth token. This automatically generates a public URL to receive external webhooks without installing ngrok separately.

Question 2

Webhook tester vs webhook.site: which should I use?

Accepted Answer

Webhook tester is free and self-hosted, offering full control and privacy, ideal for internal development. Webhook.site is a managed service with more features but potential costs and usage limits, better for quick, cloud-based testing.

Question 3

Can I persist webhook data between app restarts?

Accepted Answer

Yes, use the Redis or filesystem storage driver instead of the default memory driver. Configure it with --storage-driver and related flags to ensure data survives restarts, as explained in the storage section.

Question 4

How to run webhook tester in Docker with custom settings?

Accepted Answer

Use the Docker image with environment variables or command-line flags, like setting -p for ports and --storage-driver for persistence. The README provides example commands and highlights multi-architecture support.

Question 5

Is webhook tester good for high-traffic or production use?

Accepted Answer

With Redis for storage and pub/sub, it can handle multiple instances behind a load balancer, but performance depends on your infrastructure. It's primarily designed for debugging, not as a production endpoint.

Question 6

What happens if I use the 'latest' Docker tag?

Accepted Answer

The README warns that major upgrades may include breaking changes, so it's recommended to use specific version tags (X.Y.Z) for stability to avoid unexpected issues in deployments.
