Integrate with spam filter

I am trying to use the Forms 3rd-Party Integration plug-in with the Cleantalk spam filter to send non-spam contact form submissions to a Salesforce database.

At this point Cleantalk successfully filters spam submissions from our WordPress database, but the spam submissions continue to reach the Salesforce database via the Forms 3rd-Party Integration plugin.

Note: We are using Gravity Forms for the forms on our site.

According to Cleantalk support, “Gravity Forms has special flag about spam detection and all addons should use it (it’s a standard), but the one you are using is not.”

I am assuming that the flag they are referring to in Gravity Forms is the gform_entry_is_spam hook. (documentation: https://docs.gravityforms.com/gform_entry_is_spam/ )

How can I get the Forms 3rd-Party Integration plugin to filter out the spam submissions and not send them to our Salesforce database?

The 3rd-Party plug-in does a great job of getting the submission data to the Salesforce database; we just want to prevent the spam from getting there too.

Thank you for your help with this.
