Often, form submissions with an invalid or missing checksum (usually from bots) can produce false statistics. Here’s how to prevent that.
This feature rejects form submissions made using programmatic POSTs to the leadCapture/save2 endpoint. If your business utilizes an integration that submits forms to Marketo with that method, enabling this feature will block those submissions. Using leadCapture/save2 as an API or performing programmatic form submissions directly to it is unsupported as well as forbidden. Please ensure your business only submits forms using: Form assets, embedded forms code, Forms2.js API, or the Submit Form REST API.
Click Treasure Chest.
Next to Person Capture - Reject Invalid Checksum Values, click Edit.
Select the Enabled checkbox and click Save.
Upon enabling this feature, you may see a drop in form activity as false numbers get filtered out.
