Hello,
Is there a way to update an RSVP status to an event in NXT with a Power Automate workflow? I've currently got a way to parse through an email and retrieve the ‘Declined’ option for the event, but when I use the Update a Participant action and prefill the option to ‘Declined’, I get a 403 error: The response is not in a JSON format, cannot read server response.

It's also showing ‘Forbidden’, could it be a permissions issue?
Any advice would be greatly appreciated, thanks in advance!
