Headers

API-Version · string

Pin request, response, and webhook shapes to a specific dated API version (YYYY-MM-DD). Omit to use the version pinned to your API key (set when the key is created; new keys default to the latest version). New integrations should target the latest version.

Pattern: ^\d{4}-\d{2}-\d{2}$

Example:

"2026-07-06"

Path Parameters

evidenceId · string · required

Unique identifier of the evidence file

Example:

"urn:via:evidence:550e8400-e29b-41d4-a716-446655440000"

Response
