I ran into an error with the VerticalResponse API today, and to my surprise there were no results when searching on Google, Bing, or DuckDuckGo. Not even in the VerticalResponse documentation!

Your search - VRAPI2.NO_EMAIL_OR_POSTAL_ADDRESS_PROVIDED - did not match any documents.

The error was:

A general API error occurred: "VRAPI2.NO_EMAIL_OR_POSTAL_ADDRESS_PROVIDED" - "no email or postal address was provided, but at least one is required"

I tracked it down to a call to editListMember, which I guessed didn’t include the email_address in member_data. After adding it, the error message has gone away.

At any rate, there will now be a result if someone else searches for the error message. :)</p>
