Is it possible to download reports for multiple adwords accounts in one api call

[Garv Parmar]

Hi,

I just want to know the reason behind not allowing users to download reports of multiple accounts in one API call. Is there any kind of limitation or kind of best practice for which google is not allowing users for the same?

Thanks.

Hi,

One reason for this is simply scalability. If you ran a single report for all accounts under your manager account and you had hundreds of accounts, it's likely that you'd run into report timeouts.

If you are running reports individually for multiple accounts and you want to combine the results, you can add the ExternalCustomerId field to most reports.

Cheers,
