I am new to the messenger API, I want to send a message using a curl post request, this is my code:
import requests
ACCESS_TOKEN = an Active access token
fb_url = "https://graph.facebook.com/v10.0/me/messages"
data = {
'recipient': '{"id":4098757906843152}',
"message": {
"text": "hello, world!"
},
"messaging_type": "MESSAGE_TAG",
"tag": "ACCOUNT_UPDATE"
}
params = {'access_token': ACCESS_TOKEN}
resp = requests.post(fb_url, params=params, data=data)
print(resp)
unfortunately, I got this message <Response [400]>
any help would be appreciated
You need to change data to json.
See https://stackoverflow.com/a/26344315/603756
Starting with Requests version 2.4.2, you can use the json= parameter (which takes a dictionary) instead of data= (which takes a string) in the call
import requests
ACCESS_TOKEN = '<access_token>'
fb_url = 'https://graph.facebook.com/v10.0/me/messages'
data = {
'recipient': '{"id":<psid>}',
"message": {
"text": "hello, world!"
}
}
params = {'access_token': ACCESS_TOKEN}
resp = requests.post(fb_url, json=data, params=params)
print(resp)

I am using a rest client to do Post
My code is
def postRequest() {
def message = "{ \"fields\": { \"project\": { \"id\": \"001\" },\"summary\": \"Test Issue For Jira Integration\",\"description\": \"Creating of an issue for for projects and issue types using the REST API\", \"issuetype\": { \"id\": \"5\" } }}"
// POST
def post = new URL("https://jira/rest/api/latest/issue").openConnection();
//def message = '{"message":"this is a message"}'
post.setRequestMethod("POST")
String userpass = "user:pass" ;
String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userpass.getBytes()));
post.setRequestProperty ("Authorization", basicAuth);
post.setDoOutput(true)
post.setRequestProperty("Content-Type", "application/json")
post.getOutputStream().write(message.getBytes("UTF-8"));
def postRC = post.getResponseCode();
println(postRC);
if(postRC.equals(201)) {
println(post.getInputStream().getText());
}else
{
println(post.getInputStream().getText());
print(postRC)
}
}
I am getting 400 error code , where its getting wrong
I am successfully able to do the get request with URL
400 = bad request.
it means server tried to validate your post data and it's wrong.
usually this response contains body with explanation...
for 400+ status codes the body comes through getErrorStream() and not through getInputStream()
So, I would do it like this:
def postRequest(url, message) {
def post = new URL(url).openConnection();
//def message = '{"message":"this is a message"}'
post.setRequestMethod("POST")
String userpass = "user:pass" ;
String basicAuth = "Basic " + userpass.getBytes("UTF-8").encodeBase64()
post.setRequestProperty("Authorization", basicAuth);
post.setRequestProperty("Content-Type", "application/json")
post.setDoOutput(true)
if( !(message instanceof String) )message = new groovy.json.JsonBuilder(message).toPrettyString()
post.getOutputStream().write(message.getBytes("UTF-8"))
def response=[:]
response.code = post.getResponseCode()
response.message = post.getResponseMessage()
if( response.code>=400 ){
try{
response.body = post.getErrorStream()?.getText("UTF-8")
}catch(e){}
}else{
response.body = post.getInputStream()?.getText("UTF-8")
}
assert response.code in [200,201] : "http call failure ${response.code}: ${ response.body ?: response.message }"
return response
}
def msg = [
fields: [
project : [ id: "001" ],
summary : "Test Issue For Jira Integration",
description : "Creating of an issue for for projects and issue types using the REST API",
issuetype : [ id: "5" ]
]
]
def r = postRequest("http://httpbin.org/post", msg)
println r
The issue was related to certificate , I have to bypass the certificate validation and its working fine. Since both the application are under same network and behind same company's firewall , I have bypass the certificate validations.
Adding the skipping certificate validation part to the above code is working for me
I am trying to use one of the Amadeus flight API (flight lowest-fare search) and I think I am having issues with the authorization. The first part of the authorization works fine where I have to input the grant type, API key, and API secret. This returns the access token needed to return the flight API. However, when printing the response body I keep getting null. Could someone help me with this? I am showing my API key and API secret but that's not an issue as I can create a new one. Here's the code:
To first provide context, here's how an Amadeus API gets called after access token is retrieved from the authorization server. This endpoint returns a flight's check-in links.
curl -X GET \
"https://test.api.amadeus.com/v2/reference-data/urls/checkin-links?airlineCode=1X" \
-H "Authorization: Bearer CpjU0sEenniHCgPDrndzOSWFk5mN"
I believe my issue might in my authorization header in the flight low-fare search endpoint. I concatenated the two variables in which the token_type which has a value of 'Bearer' and the access token. In the curl example, 'Bearer' is within the speech marks. In flutter, you cannot do that as 'Authorization is the only header. Below is my code in dart:
getFlights(fromCode, toCode) async {
// getting access token
var response = await http.post(
'https://test.api.amadeus.com/v1/security/oauth2/token',
body: {
"grant_type": "client_credentials",
"client_id": "cxuxBmIvbpbv0JKzKTsJjNqc595uJVYb",
"client_secret": "buhj4SDGVrG1AzzV",
},
);
if (response.statusCode == 200) {
try {
print(response.body);
var code = jsonDecode(response.body);
if (code != null) {
var tokenType = code['token_type'];
print(tokenType);
print(code['access_token']);
var token = code['access_token'];
var bearerToken = '$tokenType ' + '$token';
print(bearerToken);
// flight low-fare search endpoint
var flightApi = await http.get(
'https://test.api.amadeus.com/v1/shopping/flight-offers?origin=LHR&destination=CDG&departureDate=2020-03-19&max=2',
headers: {
"Authorization": bearerToken,
});
var flight = json.decode(response.body);
print(flight['data']);
}
} catch (e) {
print(e.toString());
}
}
}
This the return from the authorization server which provides the access token:
{
"type": "amadeusOAuth2Token",
"username": "I REMOVED THIS",
"application_name": "I REMOVED THIS",
"client_id": "cxuxBmIvbpbv0JKzKTsJjNqc595uJVYb",
"token_type": "Bearer",
"access_token": "z8rVGOAuGaXGNUMIcVPYW76ki5Dl",
"expires_in": 1799,
"state": "approved",
"scope": ""
}
This is the return for the flight low-fare search endpoint

my Facebook messenger based Echo-bot gives a wrong status code. Though the end user(admin until now) receives the accurate echoed message, the feedback my webhook receives gives from Graph API is:
{"error":{"message":"(#100) No matching user found","type":"OAuthException","code":100,"error_subcode":2018001,"fbtrace_id":"Fan1swU4dF8"}}
Even after much reviewing and surfing, I haven't been able to find out the problem with my webhook code.Below it is:
import os, sys
import requests
from flask import Flask, request
import json
from random import random, choice
page_access_token="page_access_code"
chatbot=Flask(__name__)
#chatbot.route('/', methods=['GET'])
def verify():
print("Handling verification...")
if request.args.get('hub.verify_token', '')=='verify_token':
print("Verified!!")
return request.args.get("hub.challenge",'')
else:
print("Wrong request!!")
return "error!!"
#chatbot.route('/', methods=['POST'])
def webhook():
data=request.get_json()
log(data)
if data["object"]=="page":
for entry in data["entry"]:
for things in entry["messaging"]:
if things.get("message"):
s_id= things["sender"]["id"]
r_id= things["recipient"]["id"]
log("Sender id:"+ s_id)
log("Receiver id: "+ r_id)
try:
messaging_text= things["message"]["text"]
send_message(s_id, str(messaging_text))
except:
send_message(s_id, "Sorry!! Couldn't understand that..")
if things.get("delivery"):
log("message delivered..")
elif things.get("optin"):
pass
elif things.get("postback"):
pass
return 'ok', 200
def send_message(r_id, messaging_text):
r_id=str(r_id)
log("sending message to {recipient}: {text}".format(recipient=r_id, text=messaging_text))
params = {
"access_token": page_access_token
}
headers = {
"Content-Type": "application/json"
}
data = json.dumps({
"recipient": {
"id": r_id
},
"message": {
"text": str(messaging_text)
}
})
r = requests.post("https://graph.facebook.com/v2.12/me/messages", params=params, headers=headers, data=data)
if r.status_code != 200:
log(r.status_code)
log(r.text)
def log(message):
print(message)
sys.stdout.flush()
if __name__=="__main__":
chatbot.run(debug=True, port=5000)
PS. I am a noob so a proper description or a link will be really helpful for me to know the flaw.
I am trying to validate response body including errors in postman. How can I validate the response and text below?
{
"responseHeader": {
"publisherId": "12345",
"responseId": "abbcb15d79d54f5dbc473e502e2242c4abbcb15d79d54f5dbc473e502e224264",
"errors": [
{
"errorCode": "1004",
"errorMessage": "XXXX Not Found"
}
]
}
}
These are my tests which are failing:
tests['response json contains responseHeader'] = _.has(responseJSON, 'responseHeader');
tests['response json contains errors'] = _.has(responseJSON, 'responseHeader.publisherId');
tests["Response has publisher id"] = responseJSON.publisherId === 10003;
In the "Test" tab, parse your response body into an object, then use JavaScript to perform your tests.
var data = JSON.parse(responseBody);
tests["publisherId is 12345"] = data.responseHeader.publisherId === "12345";
Take a look at the test examples at the Postman site:

Couldn't find anything in python for FB Messenger webhook quickstart page. (https://developers.facebook.com/docs/messenger-platform/quickstart)
I went ahead and ported it myself. Figured I should share the riches. This snippet response to every message with " to you!":
import json
import requests
from django.views.decorators.csrf import csrf_exempt
FB_MESSENGER_ACCESS_TOKEN = "<Your Access Token>"
def respond_FB(sender_id, text):
json_data = {
"recipient": {"id": sender_id},
"message": {"text": text + " to you!"}
}
params = {
"access_token": FB_MESSENGER_ACCESS_TOKEN
}
r = requests.post('https://graph.facebook.com/v2.6/me/messages', json=json_data, params=params)
print(r, r.status_code, r.text)
#this allows the requst to come in without requiring CSRF token
#csrf_exempt
def fb_webhook(request):
if request.method == "GET":
if (request.GET.get('hub.verify_token') == 'this_is_a_verify_token_created_by_sean'):
return HttpResponse(request.GET.get('hub.challenge'))
return HttpResponse('Error, wrong validation token')
if request.method == "POST":
body = request.body
print("BODY", body)
messaging_events = json.loads(body.decode("utf-8"))
print("JSON BODY", body)
sender_id = messaging_events["entry"][0]["messaging"][0]["sender"]["id"]
message = messaging_events["entry"][0]["messaging"][0]["message"]["text"]
respond_FB(sender_id, message)
return HttpResponse('Received.')
And here is the FB Messenger Chatbot port on Gist
I've written a Python client for Facebook Messenger Platform: messengerbot
This is the python sample using fbmq library that works for me:
echo example :
from flask import Flask, request
from fbmq import Page
page = fbmq.Page(PAGE_ACCESS_TOKEN)
#app.route('/webhook', methods=['POST'])
def webhook():
page.handle_webhook(request.get_data(as_text=True))
return "ok"
#page.handle_message
def message_handler(event):
page.send(event.sender_id, event.message_text)
