I am using apple map web snapshots beta version to display map locations on a report I generate. There can be more than 10 map locations I need to display on the map. When I tried to load all those images images at once in a report the API returns me below response.

Code Block {"error":{"message":"Not Authorized","details":[]}}

But same code works for a single image.

Is there any limitation on the number of images I can retrieve simultaneously? Or should I follow any specific way for my attempt of using Apple Maps Web Snapshots?

Hi, a snapshot request can support a maximum of 10 different images for annotations in a single request. You can read more on it under the "Discussion" section at https://developer.apple.com/documentation/snapshots/image

Yes. That limitation I noted. I just need to check if there is a limitation on number of concurrent URLs I can trigger at a moment. For the moment, I see a lot of Not Authorized if I try to generate and view around 50 map snapshots at a time.

It seems if I generate 20 URLs and load them on same page it loads fine. But if I generate more than 25 and load them at same time one or two may get Not Authorized error.

I am using golang and I found out the signature generated was having a varying length. When the signature length is less than 87 chars, the URL returns 401 response.
