Map a field from the opportunity to the DocuSign Envelope when sending

Question

We have a date on the opportunity that is "Proposal Valid Until" and the rep adds a date. We need to map that to be the expiration (in days?) to the envelope when the users creates and envelope sending the DS from the opportunity.

Any good ideas on how to map that date field (or using another field with a formula to convert to days) then adding that to the envelope expiration on creation?

Thanks in advance.

Answer 1

Nevermind, can add

// Reminder and Expiration Settings
RES = '0,0,0,1,{!Opportunity.Default_Expiration_Days__c},2'; //Ex: '0,1,2,0,120,3'

To the custom DS button JS and it sets it as the default (given default expiration days = formula from the valid until date).
