Request for Guidance on API Rate Limit Constraints

[Gunaseelan V]

Dear GAM Support Team,

I hope this message finds you well.

We are reaching out to request your assistance regarding the rate limit constraint we are facing with the Google Ad Manager API (Ad Manager SOAP API v202411), which currently allows a maximum of 100 requests per minute.

Our Django-based application is designed to retrieve daily performance data for multiple publishers over a one-month period. For each day, we require four API calls per publisher. When aggregated across several publishers and days, our request volume quickly exceeds the current rate limit, making it challenging to collect data efficiently.

We would greatly appreciate your guidance on the following:

• Is it possible to request an increase in the API rate limit to better accommodate our usage pattern?

• Alternatively, could you recommend best practices—such as batching, scheduling strategies, or alternative API methods—to help us stay within the existing limits without compromising data accuracy or timeliness?

Thank you in advance for your support and guidance. We look forward to your advice.

Best regards,
Guna

Hi,

Thank you for contacting the Ad Manager API support team.

The first quota applied to API requests is a network-level quota. For Ad Manager 360 accounts, the limit is 8 requests per second, and for Ad Manager accounts, the limit is 2 requests per second. Going beyond this limit results in a QuotaError.EXCEEDED_QUOTA error. All API requests made on your network apply to this quota, including third-party applications that you or someone at your company has granted API access to your network.

If your application encounters quota error, carry out a strategy for retrying the API request. We recommend waiting at least 5 seconds first, and if you continue to get the error, use exponential backoff to increase the time between retries. If retrying doesn't succeed, perform an audit of your API applications to see if any users on your network are draining your quota.

Also, I recommend checking the best practices guide to stay under the limit.

Thanks,
 

Ad Manager API Team

Hi, 

Thank you for the feedback.

As per the instructions provided, we’ve already implemented the necessary steps. However, it appears that our application is generating a higher volume of API requests, which exceeds the current limit.

In this case, do you offer any paid subscription plans or quota upgrade options that we could consider?

Looking forward to your guidance.

Best regards, 
Guna.

Hi Guna,

As per API documentation, we don't have any option to increase the API quota. It is suggested to carry out a strategy for retrying the API request, use exponential backoff to increase the time between retries. 

Thanks,
