I am following the official documentation and I can see that sponsored brands has the following endpoint: https://advertising-api-test.amazon.com/v2/sb/campaigns (I suppose it was https://advertising-api-test.amazon.com/v2/hsa/campaigns in the past)
When I make the API call I get:
{"code":"NOT_FOUND","details":"Could not find resource for full path: https://advertising-api-test.amazon.com/v1/sb/campaigns","requestId":"xxxx"}
I tried different endpoints: /v3/sb/campaigns, /sb/campaigns but I still have the same response.
Is the official documentation wrong ? I do get a response when I use /hsa/ but I only get the old API version like when I try to create a campaign I get:
{"code":"405","details":"No resource method found for POST, return 405 with Allow header","requestId":"xxxx"}
