Common Use Cases

🐛 "Why is my webhook returning 404?"

Use the Compatibility Check to verify your handler workflow is active and the webhook path matches what the router is calling.

🔄 "What changed between these versions?"

Use Compare to see exactly which nodes and parameters changed, with word-level highlighting. Export as Markdown for your changelog.

📦 "My handler receives data at body.body"

The Compatibility Check specifically detects this nesting issue before you deploy. It happens when your HTTP Request body contains a field named "body".

📝 "I need to document 40 workflows"

Use the Bible Generator to auto-generate structured documentation. Upload your exports and copy the Markdown.
