X-Wix-Request-Id
Tracing a specific request through Wix platform infrastructure is the function of the X-Wix-Request-Id unofficial response header, which carries a numeric timestamp-based identifier.
Note
The "X-" naming convention for HTTP headers, "X" referring to "experimental", has been deprecated and needs to be transitioned to the formal naming convention for HTTP headers.
Usage
Wix assigns a unique identifier to each request processed by its platform. The X-Wix-Request-Id header carries this identifier in the HTTP response, making the request visible across the layers of Wix's infrastructure.
The value is a numeric, timestamp-based string encoding when the request was received. Support teams and Wix's own internal systems use this identifier to locate a specific request in server logs, correlate activity across services, and diagnose delivery problems on Wix-hosted sites. When reporting an issue to Wix support, providing this value allows engineers to retrieve the full request lifecycle from their logging systems.
The header follows a similar pattern to the general-purpose X-Request-Id convention, but the value format and infrastructure scope are specific to the Wix platform.
Values
Timestamp-based numeric identifier
The value is a long decimal string derived from a timestamp. The format encodes both timing and routing information in a numeric form, making the value sortable and traceable within Wix's internal systems. The value is opaque to clients and intended for server-side log correlation.
Example
A response from a Wix-hosted site includes a numeric request identifier. This value ties the response to a specific moment and path through Wix infrastructure.
X-Wix-Request-Id: 1766415619.68644422638815957948
The identifier is long to ensure uniqueness across Wix's distributed systems, where many requests arrive at the same millisecond.
