Limits

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 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 executeInParallel method to process accounts in parallel, and specify 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 function, and allFinished is the callback method when calling executeInParallel.

All of the changes made before the script was cancelled will be applied.

Entity limits

Scripts of Google Ads accounts

  • A single iterator will return at most 50,000 entities (keywords, ads, ad groups, or campaigns). iterator.hasNext() will return false after that, and a warning will be logged.

  • 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.

  • A single script can process at most 250,000 entities of all types. iterator.hasNext() will return false afterwards for any iterator, and a warning will be logged.

  • A single script can create 250,000 keywords and ads at the most. Successive attempts to create entities will fail, and a warning will be logged.

  • 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 executeInParallel method, a script can process up to 50 accounts.

  • The processAccount method from executeInParallel can 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.

Authorized scripts

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.

Video and shopping campaigns

The standard campaign selector (AdsApp.campaigns().get()) will filter out video and shopping campaigns from the results. Use the dedicated campaign selectors instead:
