Hello, I have tried this method curl -X POST -H "Authorization : Bearer [my_Token]" -H "Content-Type: application/json" --data-binary @"data.json" https://api.appstoreconnect.apple.com/v1/analyticsReportRequests with the contents of "data.json" being : { "data": { "type": "analyticsReportRequests", "attributes": { "accessType": "ONE_TIME_SNAPSHOT" }, "relationships": { "app": { "data": { "type": "apps", "id": "[my_appid]" } } } } } in order to send a POST request reports request to the apple store connect API, as per this https://developer.apple.com/documentation/appstoreconnectapi/post-v1-analyticsreportrequests documentation, but with no success. I have made sure my JWT is correct : headers = { "alg": "ES256", "kid": [my_private_keyid], "typ": "JWT" } payload = { "iss": [my_issuer_id], "iat": int(date_emission.timestamp()), "exp": int(date_expiration.timestamp()), "aud": "appstoreconnect-v1", "bid": "[my_bundleid]" } as per this https://developer.apple.com/documentation/appstoreserverapi/generating-json-web-tokens-for-api-requests documentation. I have also made sure my key is an admin key as it is required in order to send such a request, and I have used JSON online verificators to make sure my JSON is correct, as I was expecting it to be a JSON related issue. I really can't seem to understand why I only get 400 : bad gateway responses, any help would be appreciated on the matter.
