This page outlines various limits and limitations in Google Ads scripts that you should be aware of. These limits can change at any time without warning, so ensure that your scripts are flexible and contain error handling.
Execution time limits
Google Ads scripts
Google Ads scripts for advertiser accounts can execute for a maximum of 30 minutes, after which they will be cancelled. All of the changes made before the script was cancelled will be applied.
Ads Manager scripts
Ads Manager scripts can normally execute for a maximum of 30 minutes after
which they will be cancelled. However, if an Ads Manager script uses the
method to process accounts in parallel, and specifies a callback method, then it
can execute up to a maximum of 60 minutes before being cancelled. This is
illustrated in the figure below, where
processAccount is the parallel
allFinished is the callback method when calling
All of the changes made before the script was cancelled will be applied.
Scripts of Google Ads accounts
A single iterator will default to at most 50,000 results returned. You can modify this by calling
withLimit()on the selector.
A single selector can handle at most 10,000 IDs in
selector.withIds(). If 10,000 or more IDs are specified,
selector.get()will throw a runtime error. Similarly, specifying an
Id IN [LIST]condition with a list of IDs
10,000 will result in a runtime error.
Logging output will be truncated at 100Kb. A warning will be logged if that happens.
Scripts of manager accounts
Each account processed by an Ads Manager script gets its own quota as listed above.
When using the
executeInParallelmethod, a script can process up to 50 accounts.
executeInParallelcan return up to 10MB of data.
Bulk upload limits
The upload file is limited to 50MB and one million rows, and will be rejected upon submission if it exceeds these limits.
An upload job times out after two hours and the job will stop processing any remaining data from the uploaded file.
Quotas for Google services
The underlying Google Apps Script services impose daily quotas and hard limits on some features. For a list of these quotas and accompanying exception messages, refer to this page.
OAuth2 is used to authorize scripts. Each account has a limit of 250 authorized scripts. Beyond that limit, one of the previously authorized scripts will be deauthorized. This is only temporary, and the script can be reauthorized the next time it is opened.
If you are frequently running into this limit, you should consider using multiple user accounts to authorize different sets of scripts.
