Microsoft Face API [find similar] api key error - python-3.x

Question

So I'm trying to follow The microsoft face api documentation here for the "FindSimilar" feature. There is an example at the bottom of the page where I use this code:
########### Python 3.2 #############
import http.client, urllib.request, urllib.parse, urllib.error, base64
headers = {
# Request headers
'Content-Type': 'application/json',
'Ocp-Apim-Subscription-Key': '{api key}',
}
params = urllib.parse.urlencode({
})
try:
conn = http.client.HTTPSConnection('westus.api.cognitive.microsoft.com')
conn.request("POST", "/face/v1.0/findsimilars?%s" % params, "{body}",
headers)
response = conn.getresponse()
data = response.read()
print(data)
conn.close()
except Exception as e:
print("[Errno {0}] {1}".format(e.errno, e.strerror))
I'm getting an error where it tells me my subscription key is invalid, but I checked my azure account status and I see no issues:
b'\n\t\t\t\t\t{"error":{"code":"Unspecified","message":"Access denied due to invalid subscription key. Make sure you are subscribed to an API you are trying to call and provide the right key."}}\n \t\t'

Answer 1

Access denied due to invalid subscription key. Make sure you are subscribed to an API you are trying to call and provide the right key.
It indicates that Invalid subscription Key or user/plan is blocked. I recommand that you could check the APi Key.
headers = {
# Request headers
'Content-Type': 'application/json',
'Ocp-Apim-Subscription-Key': '3c658abc64b348c1a5...',
}
