I had a question about custom-inputs and pre-fill with the react library. Where can I find what the custom name is to pre-fill the value? I created a custom-input “Phonenumber” and I have been trying to add “Phonenumber” to the config object but it doesn’t seem to work?

I tried doing the following but no luck

<Cal
          calLink={<TEAM_LINK>}
          config={{
            name: name,
            Phonenumber: phoneNumber
          }}
        />

and (this was the custom id for the input I found from right clicking the form

<Cal
          calLink={<TEAM_LINK>}
          config={{
            name: name,
            custom_5081: phoneNumber
          }}
        />

and

<Cal
          calLink={<TEAM_LINK>}
          config={{
            name: name,
            'Phonenumber': phoneNumber
          }}
        />

@Hariom Balhara also struggling with this issue

I don't think prefill is supported with custom inputs. Embed relies on existing prefill feature.

Just thought I'd jump in and say I'd also love to see this supported. Phone number specifically as I want to use Cal.com workflows to send SMS reminders but I don't want to ask the user for their phone number when booking as I already have it

@Team Hamlet I found a way around you can end up passing it in the metadata / that is the work around
