RE: api fail in "website" conversion google ads

[Google Ads API Forum Advisor]

 Hi,

 Thank you for reaching out to the Google Ads API support team.

Note that I have removed your response from the forums as it contains the PII information.

The INVALID_CONVERSION_ACTION_TYPE error indicates that the specified conversion action has a type that is not valid for uploading click conversions. Make sure the conversion_action specified in your upload request has the type upload_clicks.

• Enhanced conversions for web are relevant for advertisers who want to track sales and events that happen on a website.
• Enhanced conversions for leads are relevant for advertisers who want to track sales that happen off a website (for example, phone or email) from website leads. They improve measurement of offline transactions that came from a website lead or visitor.

From the logs provided, it appears that you are using the UploadClickConversions method of the ConversionUploadService. But for the Enhanced conversion for web implementation, you should use the UploadConversionAdjustments method of the ConversionAdjustmentUploadService. 

You have followed the Enhanced conversions for leads implementation, but the conversion action (TTT | FORM CONTACTO) '6474193587' is a WEBPAGE conversion type. In order to avoid this error while making the request using the conversion action:(TTT | FORM CONTACTO)'6474193587', please follow the Prerequisites and API Implementation for Enhanced conversions for Web.

 

Thanks,
 

Google Ads API Team
