Keyword routing

Route messages to different target URLs based on keyword matches. Each route has its own destination and optional secret.

Fields

Field	Details
Keyword	A single word (no spaces, max 200 chars). Matching is case-insensitive.
Match type	contains (default), exact, or starts_with.
Target URL	HTTPS endpoint for messages that match this keyword.
Priority	0–100. Higher-priority routes are evaluated first.

The routing result is always present in the envelope under keyword_routing: whether a route matched, the matched keywords, and the chosen route.
