Mailerlite Integration with Bigin and Email

Hi All,

I have a problem while integrating Mailerlite with Bigin Zoho Crm or Email module.
I have 2 scenarios and both have the same problem.

Scenario 1: Watch subscriber event from Mailerlite and send an email.
Scenario 2: Watch Subscriber event from MailerLite and create a contact in Bigin Zoho Crm.

Both scenarios are working fine.

The issue is I am not able to map certain fields(custom fields) from Mailerlite to other modules.
Those fields just dont show up while mapping.

Here is scenario 1

Here is the response coming from Mailerlite showing all the fields.

Here is the mapping that doesnt show those fields

Can someone please advice ?

Thanks
Nitin
