Sending entity values to API to fetch data

Once the entity value is stored in a variable on the Code step, you can use this variable to send this to the API and fetch the real-time data. You can send this variable as a payload to the API endpoint.

The following is a sample code for fetching order details -

def main(event, context):
 """
 event['body'] is a string dict with the following keys:
 node, event, user, entities.
 Currently, we pass user_id, user_name, full_name, device_platform and language_code in the user dictionary.
 Args:
 event (dict): Data corresponding to this event
 context
 Returns
 (dict): response with statusCode and the response for the User
 """
 body = json.loads(event['body'])
 entities = body.get('entities')
 user_data = body.get('user')
 conversation_details = body.get('conversation_details')
 env_variables = body.get("env_variables")
 entity = Entities(entities)
 order_id = entity.get('capture_track_orderid_copy', '')
 order_details = get_order_details(env_variables, order_id)
 if 'Statuscode' in order_details:
 return order_details
 message = get_order_message(order_details)
 # get_order_message() returns order details in a button HSL 
 final_response = {
 'status': True,
 'message': message
 }
 response = {'statusCode': 200, 'body': json.dumps(final_response), 'headers': {'Content-Type': 'application/json'}}
 return response
def get_order_details(env_variables, order_id):
 url = "<API_ENDPOINT>"
 payload = {
 "order_id": order_id.upper()
 }
 headers = {
 'Content-Type': 'application/json'
 }
 try:
 response = requests.request(
 "POST",
 url,
 headers=headers,
 data = json.dumps(payload),
 timeout=7
 )
 except requests.exceptions.Timeout as errt:
 print("Timeout Error:", errt)
 error = "Timeout Error"
 response = generate_response(error)
 return response
 except Exception as err:
 print("Oops: Something Else", err)
 error = "Api Failure"
 response = generate_response(error)
 return response
 if response.status_code == 200:
 order_details = json.loads(response.text)
 order_details = order_details.get('results', {})
 return order_details
 else:
 print("API FAILED. STATUS CODE: ", response.status_code, response.text)
 error = "Api Failure"
 response = generate_response(error)
 return response
