Partial failures occurred: 'This Google Click ID could not be decoded., at conversions[0].gclid'.

[Darren Chamberlain]

I get the following error when uploading conversions via the API : Partial failures occurred: 'This Google Click ID could not be decoded., at conversions[0].gclid'.

The API is linked to my MMC account. The account we are sending conversions to is one of the sub accounts on the MMC. The email linked to the API is my own. And my email address is also an admin on both the MMC and the delivery account.

These are live accounts and the customers belong to that account.

The following is a GCLID from one of the conversions : Cj0KCQiApL2QBhC8ARIsAGMm-KHq121zfOVBbpKbzR0vfeI50XT-jpxIyrceB79FlK7z_fBm_h9IikgaAs2vEALw_wcB

Hi Darren,

Thank you for reaching out to our API support team.

To better investigate the cause of the error you encountered, could you also share the complete request and response logs, and request-id, generated when you attempted to upload your conversions and when this error occurred?

In addition, you may also perform a click_view request, to verify whether this GCLID would be returned for your account.

If you haven't yet, logging can be enabled by navigating to the Client libraries > Your client library (ex. Java) > Logging documentation, which you can access from this link.

You may then send the requested information via the Reply privately to author option. If this option is not available, you may send the details directly to our googleadsa...@google.com alias instead.

Best regards,

Peter Laurence Google Ads API Team
