Trace your API requests with a client-generated correlation ID.
The Wise API supports an optional correlation ID header for basic client-side tracing.
- If provided: It will echo back the correlation ID in the response header
- If not provided: No correlation ID returned in the header response
Important:
This is a simple echo. Wise does not log or store this value, all tracking must be done on your side. Do not share PII data.
