Google Ads APIs Will Soon Exceed 32-Bit Signed Integer and Now Offers 64-Bit Signed Integers
https://ads-developers.googleblog.comThis was announced starting in July 2019 and it looks like Google wanted to make sure everyone using the AdWords API, the Google Ads API beta, Google Ads scripts, and the Content API for Shopping should get their applications ready to handle ID values in that range to allow the creation of more entities with unique IDs.
Historically, the following IDs were within the maximum value of 32-bit signed integer, but will soon be exceeding this range. To avoid any issues, please make sure your applications handle these IDs within a range of 64-bit signed integer values. Also make sure that your application is ready to support a 64-bit signed integer.
