How to create the signature if I am sending a normal post request?

[bishkou]

Hi so basically I am using apple new API for analytics, so I need to send a post request to the api to create a report, the closest thing I found on the internet to my task is the create article function you have. but I am failing miserably to create the right signature.

I have succeeded in making it work with python but it didn't work in Javascript. I think I am failing at creating the right canonical_request.

here is the python line for creating the canonical_request:
canonical_request = method + url + date + content_type + json.dumps(payload)

whereas;
content_type = "application/json"
payload = {"data":{"reportType":"ARTICLE_DETAIL", "startDate":"2022-11-07", "timezone":"-0000"}}

I tried copying your method by doing this:
let canonicalRequest = Buffer(method + host + endpoint + date + content_type + JSON.stringify(payload) , 'ascii')

but unfortunately didn’t work.

Would love to know if you have any input on this or if you can help me solve this problem.

Thanks,
