Per official Instructure communications all HTTP requests, including LTI and API ones must have a user-agent header by January 17th. Instructure has provided a report to all LMS administrators that identifies developer keys that are not providing a user-agent header. Both the LTI developer key and the LTI API key for **Zoom LTI Pro** are reported to not be providing the header. I have filed two Support tickets where I’ve been told that it’s not their problem, but come January 17th, it seems like it will be. ---

Hi @David41 Thanks for reaching out to us and welcome to the Zoom Developer forum. Could you please share with me the support ticket number so I can take a closer look to it ---

Here you go: TS2103709 Second ticket I’ve filed. Still not sure they understand the problem and the urgency of it. ---

Hi @David41 Thank you so much for your patience. I was able to connect with the developer of this integration, and they confirmed that we’re implementing these changes in our December release\*. This issue should be resolved next month. ---

@David41 I will bring it up with the Support team to make sure these kind of requests do not get routed to the Dev forum ---

Do we know if the change did make it in December? I was looking at the Release Notes page, but its very out of date. [Release notes for LTI Pro](https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0069949) ---

Based on the latest report I ran within Canvas, yes, it appears that it did.
