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
executeInParallel
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 following figure, 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 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 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.
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.
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:
