How to call an external API or URL ( python code) in AWS lambda function?

The code that I included to call a API in AWS lambda is given below. urlilb3 python library is uploaded as a zip folder successfully. But when I try to access the particular intent it shows

When I included the API call in AWS lambda (python 3.6), I got

"The remote endpoint could not be called, or the response it returned was invalid" .

Why is it so? What are the prerequisites to be done before including the API calls in python 3.6. I used urllib3 python library and upload as zip folder.?? Is any other things required to do??

def get_weather(session):
    should_end_session = False
    speech_output = " "
    reprompt_text = ""
    api = "some url ...."
    http = urllib3.PoolManager()
    response = http.request('GET',api)
    weather_status = json.loads(response.data.decode('utf-8'))
    for weather in weather_status:
        final_weather = weather["WeatherText"]
    return build_response(session_attributes, build_speechlet_response(speech_output, reprompt_text, should_end_session))

Scenario : To obtain weather using an third party API 

 import urllib3

 def get_weather():
    api = "some url ...."
    http = urllib3.PoolManager()
    response = http.request('GET',api)
    weather_status = json.loads(response.data.decode('utf-8'))
    for weather in weather_status:
        final_weather = weather["WeatherText"] ## The attribute "WeatherText" will varies depending upon the weather API you are using.  
    return final_weather 

    get_weather() # simple function call

from __future__ import print_function
import json
from botocore.vendored import requests
def lambda_handler(event, context):
   print('received request: ' + str(event))
   doctor_intent = event['currentIntent']['slots']['doctor']
   email_intent = event['currentIntent']['slots']['email']
   print(doctor_intent, email_intent)
   print(type(doctor_intent), type(email_intent))
   utf8string = doctor_intent.encode("utf-8")
   utf8string1 = email_intent.encode("utf-8")
   print(type(utf8string))
   print(type(utf8string1))
   car1 = {"business_name": utf8string , "customer_email": utf8string1 }  
   r = requests.post('https://postgresheroku.herokuapp.com/update', 
   json=car1)
   #print ("JSON         : ", r.json())
   print(r.json())
   data = str(r.json())
   print(type(data))
   return {
    "dialogAction": {
    "type": "Close",
    "fulfillmentState": "Fulfilled",
    "message": {
        "contentType": "PlainText",
        "content": "Thank you for booking appointment with {doctor} 
{response}".format(doctor=doctor_intent,response=data)
     }
    }
   }

Try printing response.data so you can see it in the logs. That might give you a clue. I would also try to switch to Python Requests instead of URLLib3. You may also need to set the Content Type depending on the implementation of the API you're calling.
