Is it possible to setup validation on an address field to check if address falls inside specific boundaries? I’ve been researching using Google Geocode API, but not sure how to integrate with Gravity Forms for validation.
You can certainly use the Google Geocode API (or anyone’s API) with the gform_field_validation filter. Setting that up is outside the scope of Gravity Forms support.
I’ll leave the topic open in case someone has done this and would like to share their approach.
