Autodesk plans to make format changes to the event delivery request headers in the Webhooks API when delivering the events to external callback URLs. Specifically, we will convert some of the existing header values. This is a courtesy notice, as these header fields have not previously been publicly documented, and they are intended to be used internally for tracing purposes only.
The format changes will impact the following undocumented header fields:
- x-ads-ul-ctx-tracking-id
- x-ads-ul-ctx-head-span-id
- x-adsk-delivery-id
The table below shows differences between before and after the change:
