Pre Populate custom field while creating a new record

Question

I am trying to pre-populate a lookup field while creating a new Account record and as per documentation we can use field name instead of custom fieldId.

Classic Way:

https://test--dev.my.salesforce.com/a06/e?
CF00N71000001zWxy=Test+User
&CF00N71000001zWxy_lkid=0010500000IZ8jXAAT

New Way

https://test--dev.lightning.force.com/lightning/o/Account/new?defaultFieldValues=
Client__c=0010500000IZ8jXAAT

Is there any way we can pre-populate Text for a lookup field in lightning just in the same way we used to do CF00N71000001zWxy=Test+User

Answer 1

I created a new button on the Account object to create the contact which prepopulate the Account look up.

The Custom Account Name field is a custom look up field for the account object.

See if this helps for you.
