Pysnow Usage of sysparm_query_category

As I cannot see any reference on how to use properly the sysparm_query_category, may I confirm on how did you append the sysparm_query_category in get request?
Added below line of codes. I hope someone can help and guide me as I'm new to ServiceNow. Thanks!
from pysnow import Client
...
resource = self.client.resource(api_path=F"/table/{table}")
resource.parameters.add_custom({"sysparm_query_category": "cat_read_generic"})
request = resource.get(query=query, fields=fields)

I am not aware pysnow API. I hope this helps. Else refer to the comment above.
#Need to install requests package for python
#easy_install requests
import requests
# Set the request parameters
url = 'https://demonightlycoe.service-now.com/api/now/table/incident?sysparm_query=category%3Dcat_read_generic&sysparm_limit=1'
# Eg. User name="admin", Password="admin" for this code sample.
user = 'admin'
pwd = 'admin'
# Set proper headers
headers = {"Content-Type":"application/json","Accept":"application/json"}
# Do the HTTP request
response = requests.get(url, auth=(user, pwd), headers=headers )
# Check for HTTP codes other than 200
if response.status_code != 200:
print('Status:', response.status_code, 'Headers:', response.headers, 'Error Response:',response.json())
exit()
# Decode the JSON response into a dictionary and use the data
data = response.json()
print(data)

Upon checking and testing, we can use the add_custom
client.parameters.add_custom({'foo': 'bar'})
that would be additional to the parameters like &foo=bar

What are Callback URLs and how do I set them up

I am working with an API from SignalHire. The API docs reference a callback URL but I don't have a very technical background and am not sure how to set this up. I've done some digging but I am still very confused and not sure how to proceed. Here is my code:
API_KEY = 'testapikey'
headers = {'apikey': API_KEY,
'callbackUrl': ''}
data = {'items': ['https://www.linkedin.com/in/testprofile/']}
response = requests.post("https://www.signalhire.com/api/v1/candidate/search", headers=headers, json=data)
if response.status_code == 200:
print(json.dumps(response.json(), sort_keys=True, indent=4))
I just need help understanding what a callback url is and how I can set that up.

When you post the search request, you won't get back results immediately. Instead, you'll get a 201 response that lets you know that SignalHire has received your request.
When the results are ready, they will be posted to the the URL you provide. It should be an endpoint that you write that sends a 200 response back to SignalHire acknowledging that it has received the search results.

Keep getting a 401 error when trying to pull data

I'm fairly new to using web APIs and pulling data and i'm also pretty new with python. My goal is to make a stat-tracker app but I keep getting a 401 when I try and pull the data.
I've printed out the entire url just to make sure I didn't get it wrong. I copied and pasted the API key exactly so that shouldn't be a problem
api_token = 'api key in python file'
api_url_base = 'https://public-api.tracker.gg/v2/apex/standard/'
headers = {'Content-Type' : 'application/json',
'Authorization' : 'Bearer {}'.format(api_token)}
def get_player_profile():
api_url = '{}profile/psn/Daltoosh'.format(api_url_base)
response = requests.get(api_url, headers=headers)
if response.status_code == 200:
return json.loads(response.content.decode('utf-8'))
else:
return response.status_code, api_url
print(get_player_profile())
#player_profile = get_player_profile()
#if player_profile is not None:
# print("Career Stats:")
# for k, v in player_profile['profile/psn/Daltoosh'].items():
# print('{0}:{1}.format(k, v)')
#else:
# print('[!] Data Request Failed [!]')
I expected a status code of 200 but there seems to be a problem authenticating.

I'm not too well versed in the web API that you are using, but I think you might be using the API token incorrectly. I don't think that specific API requires a Bearer token, but instead a separate header called TRN-Api-Key.
So maybe write something like this:
headers = {'Content-Type' : 'application/json', 'TRN-Api-Key' : api_token}
If you look here, you should be able to read up on how to set up authentication.

Facebook webhook making multiple calls for the same message?

I made and echo bot on AWS with Python and serverless.
I keep getting the same request again and again.
I read the faq where it says u have to deliver a status code 200 else it will keep retrying the webhook.
I'm not sure How I do this.
I have noticed that the sequence number is always the same for the calls so I assume the reply I sent was not acknowledged.
my code is here
import os
import json
import requests
import random

I have given the status code 200 in soo many places and I'm not sure y I still keep getting the same problem.

If you are getting multiple messages your server did not return 200 status code to webhook request from Facebook server. This means an error occurred on your part otherwise 200 should be returned. It looks to me that problems are in following lines:
params = {"statusCode": 200,"access_token": os.environment['accesstoken']}
headers = {"statusCode": "200","Content-Type": "application/json"}
data = json.dumps({"statusCode": "200","recipient": {"id": send_id},
"message": {"text": msg_txt}})
Firstly you are passing statusCode in a data body of message and according to this documentation message response should not contain it.
Another problem could be sending status code inside params. I would remove status code completely from send_message method. I doubt its needed there. You are basically trying to return status 200 on wrong end. You are trying to return it on output instead of input (from Facebooks point of view).
So its quite possible you are correctly getting message from Facebook but you are still returning wrong status code because you are calling send_message method from inside messaging event and send_message method should return status "400 bad request" because you are sending faulty request. Thus your server also returns wrong response code.
Just make sure your code works correctly and 200 should be returned.
EDIT:
So i would try with following code:
params = {"access_token": os.environment['accesstoken']}
headers = {"Content-Type": "application/json"}
data = json.dumps({"recipient": {"id": send_id},
"message": {"text": msg_txt}})

I'm working on a Facebook Messenger chatbot with a Node/Express server and was having the same exact issue. The server was appropriately sending 200 responses and yet the issue persisted. I resolved the problem by caching message ID's and checking for duplicates before processing:
var NodeCache = require('node-cache');
var myCache = new NodeCache();
app.post('/webhook/', function(req, res) {
var messageID = req.body.entry[0].messaging[0].message.mid;
var checkForDupe = myCache.get(messageID);
if (checkForDupe == undefined) {
var setID = myCache.set(req.body.entry[0].messaging[0].message.mid, req.body.entry[0].messaging[0].message.mid);
//Handle message .....
I hope this helps someone. It was driving me nuts.

Your webhook callback should always return a 200 OK HTTP response when invoked by Facebook. Failing to do so may cause your webhook to be unsubscribed by the Messenger Platform. (copied from messenger docs.)
You have to search problem from your returning response. It is not with the sending data.
response = requests.post(POST_MESSAGE_URL, headers={
'Content-Type': 'application/json'
}, params={
'access_token': ACCESS_TOKEN
}, data=json.dumps(DATA_JSON)
this code working fine for me

I am from Java background but still I will try to help you.
In handle webhook challenge I can see you returning 200 status code
But in handle messaging block 200 is not returned You have set 200 status code in send message. But it will not work you have to return 200 from handle messaging block.
Also 200 should be returned even if any exception occurs in this block otherwise on exception it will get blocked. So may be in finally block you can return 200.

As an alternative, you can use chatbotproxy.com which always return 200 in 1ms and pass the exact same request to your endpoint. Since immediate response is very important for Facebook Messenger platform, 1 millisecond time is a very promising feature. If you need help to try, let me know.

DELETE Request in Python "requests" module not working with body

I have been using this function to handle http requests with no problems:
def do_request(self, method, url, **kwargs):
params = kwargs.get('params', None)
headers = kwargs.get('headers', None)
payload = kwargs.get('data', None)
request_method = {'GET':requests.get, 'POST': requests.post, 'PUT': requests.put, 'DELETE': requests.delete}
request_url = url
req = request_method[method]
try:
res = req(request_url, headers=headers, params=params, data=json.dumps(payload))
except (requests.exceptions.ConnectionError, requests.exceptions.RequestException) as e:
data = {'has_error':True, 'error_message':e.message}
return data
try:
data = res.json()
data.update({'has_error':False, 'error_message':''})
except ValueError as e:
msg = "Cannot read response, %s" %(e.message)
data = {'has_error':True, 'error_message':msg}
if not res.ok:
msg = "Response not ok"
data.update({'has_error':True, 'error_message':msg})
if res.status_code >= 400:
msg = 'Error code: ' + str(res.status_code) + '\n' + data['errorCode']
data.update({'has_error':True, 'error_message': msg})
return data
When I have to do a DELETE request without body entity I have no problems but when I try to add one (when required by the server) I get an error message from the server telling that the body cannot be null as if no body has been sent. Any ideas why this might be happening? I'm using requests module and python 2.7.12. As far as I know data can be send in a DELETE request. Thanks!

There are problems with some clients and some servers when DELETE includes entity body: Is an entity body allowed for an HTTP DELETE request? for example & lots of search results.
Some servers (apparently) convert the DELETE into a POST, others simply perform the DELETE but drop the body. In your case, you've investigated that indeed, the body of a DELETE is dropped by the server & it has been suggested that you change the DELETE to POST.

Mmm... I can send a DELETE with body with Postman and works OK. But I cant get the same result with Requests 2.17.3
This is a issue related to Requests
