Can I update a Custom Field in Marketo via Javascript API munchkinFunction associateLead?

[Anonymous]

Hey, I see documentation for updating Custom Fields via the REST API (link to doc) however I have not been able to find any information that explicitly states whether it is possible to update a Custom Field via the Javascript API / Munchkin / Associate Lead?

Many thanks in advance for any help.

Absolutely. This is one of the fundamental Munchkin features. Use the SOAP (a.k.a. form) name.
