Disclaimer

Redline is an independent developer utility. It is not affiliated with, endorsed by, or connected to Stripe, GitHub, Twilio, or any other API or webhook provider referenced on this site as an example — those names are used purely to illustrate what kind of traffic the tools handle.

The API Tester forwards your request to the target server and returns exactly what that server sends back, including its status code, headers, and body. We don't modify, validate, or guarantee the accuracy of third-party responses — you're seeing what the target API actually returned, for better or worse.

Redline is meant for testing, debugging, and development workflows. It is not designed, and should not be relied on, as a component of a production system — for example, don't point a live production webhook permanently at a Redline inbox and depend on it for uptime or delivery guarantees.

You're responsible for verifying that your use of Redline complies with the terms of service of any API or provider you test against, and with any laws applicable to your use case.
