SEEK recently updated the way webhook events are delivered, including a change to the casing of HTTP headers on those requests. This may have impacted integrations that incorrectly treat HTTP header names as case-sensitive, even though HTTP header field names are case-insensitive under RFC 9110. For reference: RFC 9110, section 5.1 https://www.rfc-editor.org/rfc/rfc9110.html#section-5.1 This affected all webhook events sent between 2026-07-14 16:00:00 and 2026-07-15 14:30:00 AEST. To mitigate the affect of this issue SEEK are replaying all webhook events that were sent during the incident window.
