RE: random (404) not found error occurring in google ad manager soap api

[Ad Manager API Forum Advisor]

Hi,

Thank you for contacting the Ad Manager API support team.

Please be informed that I have removed your response from the forums as it contained the PII information.

 

I understand that you are facing '404 Not Found' error while accessing the getLineItemsByStatement method via Ad Manager API. I'm checking your concern with the rest of our team and one of my teammates will reach out to you once we have an update.

Thanks,

Hi,

To assist further, Please provide us with the following details for further investigation. 

• Could you please confirm that  this is happening in all environments or just their prod environment?

• Can you please confirm whether you are able to access this URL (it shows the API schema) from your local machine? (https://ads.google.com/apis/ads/publisher/v202502/LineItemService)

• Are you using any proxy, or is there a corporate firewall? 

Thanks,

The same phenomenon continued today, 2025-11-13, from 00:00 to 05:00 (KST).
Currently, communication errors are not occurring.
We are concerned about when this phenomenon might appear again.

Here are the answers to the questions you inquired about:

• Could you please confirm that  this is happening in all environments or just their prod environment?

 => It occurred in all environments (Development and Production).

• Can you please confirm whether you are able to access this URL (it shows the API schema) from your local machine? (https://ads.google.com/apis/ads/publisher/v202502/LineItemService)

=> When I entered the URL on my local PC, I received the following response:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>No such operation: (HTTP GET PATH_INFO: /v202502/LineItemService)</faultstring>
</soap:Fault>
</soap:Body>
</soap:Envelope>

• Are you using any proxy, or is there a corporate firewall? 

=> We are not using a proxy, and we have a company firewall.

Currently, I see other people on the forum experiencing the same phenomenon as me.
It seems that communication is continuously succeeding and failing.

Is there really no problem on your server side?
Have your server IP addresses changed?

Hi,

 

Thank you for providing the necessary details.

I attempted to replicate the issue with retrieving line items on our network, but I was successful and did not encounter any errors. Since I was unable to reproduce the problem locally, I have raised your concern to the wider team for further investigation. I will follow up with you as soon as we have an update.

We appreciate your patience while we look into this.

 

Thanks,
 

Ad Manager API Team

Hello,

I sent you GAM network Ids with private message.

This issue appears not for all requests, it appears and suddenly becomes stable, and after sometime it doesn't work again. You cannot reproduce it with one request. You have to check the logs in the timeframe when it happened.

- It happens in all prod environments of GAM, not only one GAM network

- That error appears with LineItemService, CreativeService, CustomTargetingServic, ReportService and other endpoints

- No, we don't use any web proxy

It happened approximately between 2025-11-12 18:30 CET - 20:00 CET. Please check the logs on your end.

Our system experienced the same phenomenon today as well.
From 2025-11-13 23:49:41 to 2025-11-14 04:23:05 (KST),
we received the "(404) Not Found" response again during this time window.
The error log is identical to the one we shared previously.

When can we expect an update regarding the cause and resolution of this issue?
