Every API response includes a request ID. Use it when debugging a request, comparing logs, or contacting Syntage support about a specific API call. The request ID is returned in the X-Request-ID response header. 
curl -i 'https://api.syntage.com/entities' \
  --header 'Accept: application/ld+json' \
  --header 'X-Api-Key: {apiKey}'

HTTP/1.1 200 OK

When to use it

Include the request ID when you contact support or investigate a failed request. It lets Syntage identify the exact API request without relying on timestamps, endpoint names, or partial payload details.
Log the X-Request-ID value with your own application logs when possible. This makes it easier to trace a request across your application and Syntage.
