CLARIFY: If Forms is a REST API, why does it use SOAP names?

[Robb_Barrett]

In using the form.vals function for external forms, I was under the impression that it would use the REST API field names since it's a REST API. To get the function to work correctly, the SOAP field names need to be used. This is doin' me a confuse...can someone clarify why a REST API would use SOAP naming?

Here's an example of working code:

form.vals({"Phone":"{{lead.Phone Number}}",

                 "FirstName":"{{lead.First Name}}",

                 "LastName":"{{lead.Last Name}}",

                 "Company":"{{company.Company Name}}",

                 "Email":"{{lead.Email Address}}",

                 "State":"{{lead.State}}",

                 "Title":"{{lead.Job Title}}",

                 "City":"{{lead.City}}",

                 "Address":"{{lead.Address}}",

                 "PostalCode":"{{lead.Postal Code}}"

                });

And here are the field names, as exported:

REST API Name

SOAP API Name

Friendly Label

firstName

FirstName

First Name

lastName

LastName

Last Name

company

Company

Company Name

email

Email

Email Address

state

State

State

title

Title

Job Title

phone

Phone

Phone Number

(Etc)

The client-side Forms API isn't a REST API.
