Create API to Consume Whatsapp API

Let’s create a file and add the below code into this file.

from flask import Flask
from flask_restful import Resource, Api
from flask_cors import CORS
import requests
app = Flask(__name__)
CORS(app) ## To allow direct AJAX calls
@app.route('/getGroups', methods=['GET'])
def home():
headers = {'Authorization': 'Bearer your-auth-token', 'Content-Type': 'application/json'}
res ='https://your-webapp-hostname:your-webapp-port/v1/groups', headers=headers)
return r.json()
except Exception as e:
print('unable to get groups.')
if __name__ == '__main__': = True)

The above HTTP request includes the following components:-

  • URL — The URL of the server along with the API endpoint for the request.
  • Method — The action being requested of the endpoint. You can use methods like POST, GET, DELETE, PATCH, and PUT.
  • Headers — You can add Meta information about the request like request type, token etc.
  • Body — This contains the payload data.

The above call return with the response object, The response object will have all available groups with ids. The response as per docs as like below –

"groups": [
{"id": "group-id1"},
{"id": "group-id2"}

The Whatsapp Response Object will have the following properties –

  • HTTP Status Code — Status codes are issued by a server in response to a request made to the server. See HTTP Status Codes for more information.
  • Meta — Contains generic information such as WhatsApp Business API Client version.
  • Payload — Only returned with a successful response. The payload object name and contents vary based on the request. In the above examples, the payload is contacts because we sent a request to the contacts endpoint.
  • Errors — Only returned with a failed request. Contains an array of error objects that are present when there is an error. See the Error Codes for more information.
