Custom Fields + Zapier (PLEASE!)

I’ve been trying to integrate this plugin with another platform using Zapier (thanks for making it available).

Everything seems to work but once i’m creating the Zap it only lets me access the predefined data fields (including some I actually deactivated, like rates or discounts), but the custom fields I created for my form and reservations are not listed, so I can’t proceed with the integration I had in mind.

Is there any way to access that data in Zapier so that I can properly set up the integration? Could you make the zapier integration code “dynamic” so that it passes through all the fields defined in the form?

I guess it’s all about changing the functions that share data to Zapier, so if anyone else has an answer to that, I’ll be happy too!
