Bookings to CRM - New Events and Contacts

Bookings to CRM - New Events and Contacts

Hello,

I have an issue with appointments taken by clients from a Zoho Bookings page. Previously when an appointment was reserved, if there were no client created in Zoho CRM, it would create it in the CRM through the integration between both platform.

One more thing, it filled a field (How client contacted) with the value Zoho Booking in the CRM at creation. This field is not in the Zoho Bookings page. However since maybe april it stopped working properly. Since i'm not the original creator of this Zoho Bookings, I tried my best to solve the problem(Custom worflows in Bookings or CRM, Zoho Workflow), but can't find a satisfactory solution.

I've seen that a new version of Bookings came out in april, could it be linked to if?

Is there a way to add automatically a static value in a Contact's field when it comes from Zoho Booking?
