Hi @sylvaint,

Since this is a recurring webinar (of registration\_type 2), you will need to pass the occurrence ID to your request in order for this to update successfully:

Please pass this as a query parameter and this should resolve the issue:

Thanks, and let me know if you continue to have any trouble.

Best,  
Will
