Hi CM360 API Support Team and Community,

Since September 10, 2025, we’ve been experiencing frequent 503 "UNAVAILABLE" error responses when making POST requests to https://dfareporting.googleapis.com/dfareporting/v4/userprofiles/XXX/conversions/batchinsert. These errors occur multiple times daily. We’ve been using this API since December 2023 without issues until now, so the sudden increase in 503 errors is unexpected.

To mitigate this on our end, we’ve implemented exponential backoff in our client, which has resolved the issue for us by retrying failed requests. However, the sudden onset and frequency of these errors seem unusual, and I’m concerned there might be an underlying issue on the server side.

Could the DCM API Technical Support Team investigate what might be causing this behavior? For context, we’re using the Google API Client Library with Java, and the errors started occurring without any changes to our code or configuration.

Any insights or updates would be greatly appreciated. Happy to provide more details if needed!

Thanks,

Hendrik Boon

Hi,

Thank you for reaching out to the DCM API support team.

I understand that you are receiving 503 "UNAVAILABLE" error responses when making the Batch Insert method. The 503 error message typically indicates that the issue originates from within the server or backend system while handling your request. There are several potential causes for this, including Server Overload, Data Format, Connectivity Issues, or System Configuration. I would like to kindly ask you to try making the request again. In order to investigate further can you please share us with the following details:
