SSV URL confirmation for AdMob Reward Ads Returning 403 Error

[matsuya kazuhiro]

Hello.
I am encountering a 403 error when attempting to confirm the SSV (Server-Side Verification) URL for AdMob reward ads. The connection URL itself appears correct, as I have confirmed that the processing on the receiving server is functioning properly.

As background, I created a reward ad unit in the AdMob console, entered a callback URL for SSV, and then clicked the confirmation button on the screen to confirm the URL. Previously, this URL confirmation worked without issues, but it now consistently returns a 403 error. Additionally, no requests are reaching the destination URL, and aside from the 403 error, there are no further details to indicate the cause.

Could you please help me identify the cause and suggest any possible solutions? I am relatively new to AdMob and may be missing some details, so any guidance you can provide would be appreciated.

Thank you for your assistance.

Hi,

Thank you for contacting the Mobile Ads SDK Support team.

The 403 Error happens when the web page (or another resource) that you’re trying to open in your web browser is a resource that you’re not allowed to access. It’s called a 403 error because that’s the HTTP status code that the web server uses to describe that kind of error. I would recommend to Double-check that the SSV URL you entered in the AdMob console is correct and accessible. Make sure you’re using the correct protocol. AdMob requires HTTPS for security.

Could you confirm whether you have followed all the steps mentioned in the help center article to Validate rewarded ad views with server-side verification. You can also refer to this to get more information about the SSV.
