This is incorrect as we have rotated it in Apr 2020 already. I would expected this notice to have come just before Oct 2020. I have set a reminder to do this then ... There seems to be an issue on the notification check ...
Thanks for reaching out. I'm happy to check out the notificaiton system if you can send me your hub id. Also, can you double check that the notificaiton didn't come from a different portal?
Checking that portal, looks like the hapikey was rotated in April. I'm not seeing any rotation notificaitons related to hub 5345274. If you have any other accounts that use hapikeys, I'd recommend just double checking them and rotating the hapikeys that need rotating. Otherwise, if you see any other weird notifications feel free to contact our Support team: https://help.hubspot.com/
