| Changes to GCLID field length in AdWords API Posted: 12 Feb 2014 12:29 PM PST In AdWords API v201309 we released a new Google Click ID field (GCLID) in the Click Performance report. Originally, this field value was limited to 26 characters. We will be extending the maximum length of this field in order to support improvements to our advertising system. Starting March 31st 2014, the value of GCLID can be up to 100 characters long. Since this value is used in many client systems, we're giving you advance warning of this change. Make sure your log, storage and redirecting systems can handle the extended size of the GCLID value. Note: as a result of this change, the Click Performance report will only be available for dates up to 90 days before the time of a request. If you need the older click data, download and store these details before March 31st, 2014. If you have any questions about the change, reach out to us on the forum or via the Google+ page.  |
