Side-by-Side Payload Comparison
You can now compare any two webhook requests to quickly identify what changed between them. This is especially useful when debugging why a webhook started failing or when verifying that a provider is sending the expected payload format.
How It Works
From any request detail view, click Compare to select a second request. CatchHook will show a clean, color-coded diff of:
- Headers -- see which headers were added, removed, or changed
- Body -- JSON-aware semantic diff that understands nested structures
- Query parameters -- spot differences in URL parameters
When to Use It
- A webhook that was working suddenly starts failing -- compare a successful delivery with a failing one
- A provider announces payload changes -- compare old vs. new format
- Debugging signature verification -- compare the raw body between attempts
