Extension Setting Services - operation limit

[Nati Yonatan]

according to https://developers.google.com/adwords/api/docs/guides/extension-settings

Note: Since their data elements can be very large, extension setting services have an operations-per-request limit of 250 (instead of the usual 5,000).

what is the operation limit exactly?

Because in the mutate request we send a list of operations, and each operation has a list of extensions.

So is the limit on the operations level ? or do I need to count the total extensions in all operations to be under 250?

Hi Nati,

Thank you for posting your concern.

With regard to your question, one extension setting should be equivalent to one operation so technically speaking, you can only use 250 operations/extension settings per request.

Let me know if you have further questions.

Is there a limit for the extensions list inside the extension settings?

Hi Nati,

Thanks for the reply.

There is no limit specified in our documentation for the number of extensions that you can include inside one extension setting object. However, since its data elements can be very large, the limit was adjusted to be 250 operations per request limit, and one extension setting object should equate to one operation.

Furthermore, please note that in every extension setting, the type of extension should be the same. Please see Add sitelinks to a campaign sample code, you can see that only sitelinks are included in this extension setting.
