Do any of the Contact Us form examples update an existing contact?

Yes! Solve’s Wufoo integration method provides an option to update an existing contact if it already exists. This is done by searching email field(s). Select the “Check duplicates” option to update existing Solve contacts (instead of making a new record) for your respective form under the Solve menu (top right) > Add-ons > Wufoo.

Our API PHP example code compares the ‘businessemail’ value provided against all email addresses in the system. If found it will update the first matching contact.
