Hi all,
I'm trying to use WC1 API with Python requests, but I'm facing issue to get the authorization. Below you can see the code I'm using:
import hmac, hashlib, base64, requests as r
from datetime import datetime
dt = datetime.utcnow().strftime("%a, %d %b %Y %H:%M:%S GMT") # Wed, 14 Dec 2022 23:54:18 GMT
app_key = "******"
app_secret = "****************"
gateway_host = 'api-worldcheck.refinitiv.com'
gateway_url = '/v2/'
scope = 'groups'
dataToSign = f"(request-target): get {gateway_url}{scope}\n host: {gateway_host}\n date: {dt}"
print(dataToSign,'\n')
digest = hmac.new(bytes(app_secret , 'UTF-8'), msg = bytes(dataToSign , 'UTF-8'), digestmod = hashlib.sha256).digest()
signature = base64.b64encode(digest).decode()
authorization = f'Signature keyId="{app_key}",algorithm="hmac-sha256",headers="(request-target) host date",signature="{signature}"'
print(authorization,'\n')
header = { "Date": dt, "Authorization": authorization,}
res = r.get(f'https://{gateway_host}{gateway_url}{scope}', headers=header)
print(res.url, res.status_code)
However I'm always getting the error code 401.
Would you have an example to how to get such authorization using python?
