Pinterst api: not able to get access token - Stuck in Oauth flow

Using v5 of the pinterest api and stuck on the authentication flow: https://developers.pinterest.com/docs/getting-started/authentication/
Completed the first step and got the access code.
However, I get the below error when I try to use this code to get the access token.
{"code":1,"message":"Missing request body"}
Here is my code:
client_id= 'my_client_id'
client_secret = 'my_client_secret'
data_string = f'{client_id}:{client_secret}'
token = base64.b64encode(data_string.encode())
headers = {
'Authorization': 'Basic ' + token.decode('utf-8'),
'Content-Type': 'application/x-www-form-urlencoded',
}
url = "https://api.pinterest.com/v5/oauth/token"
code = "my_code_that_i_got_in_the_first_step"
params = {
'grant_type':'authorization_code',
'code': code,
'redirect_url':'https://my_redirect_uri'
}
r = requests.post(url, headers=headers, params=params)
print(r.json())

Below is the correct way to get the access token:
client_id= 'my_client_id'
client_secret = 'my_client_secret'
data_string = f'{client_id}:{client_secret}'
token = base64.b64encode(data_string.encode())
headers = {
'Authorization': 'Basic ' + token.decode('utf-8'),
'Content-Type': 'application/x-www-form-urlencoded',
}
url = "https://api.pinterest.com/v5/oauth/token"
code = "my_code_that_i_got_in_the_first_step"
data= {
'grant_type':'authorization_code',
'code': code,
'redirect_uri':'https://my_redirect_uri'
}
r = requests.post(url, headers=headers, data=data)
print(r.json())
In my question, I had mistyped redirect_uri as redirect_url. Also, when sending a POST, you should use data instead of params. See the comment by Amos Baker.

"unsupported_grant_type" when using Google's urlfetch to get an oauth token from PayPal. Using "requests" works

I've been trying (and failing miserably) to use google's urlfetch module (python within app engine's local server) to retrieve a token from paypal. It works as follows using the "requests" module outside of app engine:
url = base + "/v1/oauth2/token"
payload = {
'grant_type': 'client_credentials',
}
auth_encoded = APP_CLIENT_ID + ":" + APP_SECRET
auth_encoded = base64.b64encode(auth_encoded)
##headers = {'Content-Type': 'application/json', 'Authorization': 'Basic ' + auth_encoded}
headers = {'Content-Type': 'application/x-www-form-urlencoded', 'Authorization': 'Basic ' + auth_encoded}
r = requests.post(url,headers=headers,params=payload)
print r.text
... but I get this message when trying the same thing with urlfetch:
{"error":"unsupported_grant_type","error_description":"Grant Type is NULL"}
... here's the code that I'm using:
url = base + "/v1/oauth2/token"
payload = {"grant_type": "client_credentials"}
auth_encoded = APP_CLIENT_ID + ":" + APP_SECRET
auth_encoded = base64.b64encode(auth_encoded)
headers = {'Content-Type': 'application/x-www-form-urlencoded', 'Authorization': 'Basic ' + auth_encoded}
result = urlfetch.fetch(
url=url,
method=urlfetch.POST,
headers=headers,
payload = payload
)
... I've tried everything that I can think of. Should be a simple thing.

This API call is formatted as application/x-www-form-urlencoded , not JSON.
Therefore:
payload = "grant_type=client_credentials"
or
import urllib
payload = urllib.urlencode({"grant_type": "client_credentials"})

how do I connect with salesforce with python requests?

Traceback error while connecting with salesforce API: [{'message': 'INVALID_HEADER_TYPE', 'errorCode': 'INVALID_AUTH_HEADER'}]
What is the problem?
My python codes are as follows:
client_id = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
client_secret = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
redirect_url = 'http://localhost/'
cm_user = 'XXXXXXXXXXXXXXXXXXXXXX'
cm_pass = 'XXXXXXXXXXXXXXXXXXXXXX'
auth_url = 'https://login.salesforce.com/services/oauth2/token'
response = requests.post(auth_url, data = {
'client_id': client_id,
'client_secret': client_secret,
'grant_type':'password',
'username': cm_user,
'password': cm_pass
})
json_res = response.json()
access_token = json_res['access_token']
auth = {'Authorization': 'Bearer' + access_token}
instance_url = json_res['instance_url']
url = instance_url + '/services/data/v45.0/sobjects/contact/describe'
res = requests.get(url, headers=auth)
r = res.json()
print(r)

You are missing a space after the word Bearer, which renders your authorization header invalid.

converting python oauth to postman request

I am trying to convert successful python (flask) OAuth 2.0 authentication / api request into Postman.
My current process is:
From the front end, I hit an /auth endpoint in python using fetch:
fetch("/auth")
.then(function (response) {
return response.json();
})
.then(function (json) {
const code = json.code;
window.location = `[hostname.com]/auth/authorize?request_token=${code}&redirect_uri=http://[hostname]/menu`;
});
The backend flask auth endpoint looks like this:
url = 'https://[hostname].com/v3/oauth/request'
headers = CaseInsensitiveDict()
headers['Host'] = '[hostname].com'
headers['Content-Type'] = 'application/json'
headers['X-Accept'] = 'application/json'
data = json.dumps({'consumer_key': 'XXXX', 'redirect_uri':'[hostname]/success'})
resp = requests.post(url, headers=headers, data=data)
json_resp = json.loads(resp.content)
auth_code = json_resp['code']
auth_resp = {'code': auth_code}
return jsonify(auth_resp)
The access endpoint takes that auth code to get the token
cur_auth = session.get('auth_code',None)
url = 'https://[hostname.com]/v3/oauth/authorize'
headers = CaseInsensitiveDict()
headers['Host'] = '[hostname].com'
headers['Content-Type'] = 'application/json; charset=UTF-8'
headers['X-Accept'] = 'application/json'
data = json.dumps({'consumer_key': 'XXXX', 'code': cur_auth})
resp = requests.post(url, headers=headers, data=data)
json_resp = resp.json()
access_token = json_resp['access_token']
username = json_resp['username']
session['access_token']=access_token
session['username']=username
access_resp = {'access': access_token, 'user': username}
return jsonify(access_resp)
But when I try to translate this into a postman request, I can't really understand where some of the things like the consumer_key request_token and code get defined.
I'm currently getting a 400 bad request with this setup:
where the consumer_key is in Postman's client secret field, and where
https://[hostname].com/v3/oauth/request is in Postman's auth field and
https://getpocket.com/v3/oauth/authorize is in Postman's access token url field.

How to update a pull request through Github API

I want to update the title of a pull request and performing the below to achieve it :- (followed this doc https://developer.github.com/v3/pulls/#update-a-pull-request)
data = {"title": "New title"}
url='https://hostname/api/v3/repos/owner/repo/pulls/80'
token = 'my-token'
headers = {'Content-type': 'application/json', 'Accept': 'application/json', 'Authorization': 'token %s' % token}
resp = requests.patch(url, data=json.dumps(data), headers=headers)
print resp.json()
What am I missing ? Please help.

The following worked for me:
import requests
token = "my-token"
url = "https://api.github.com/repos/:owner/:repo/pulls/:number"
payload = {
"title": "New title"
}
r = requests.patch(url, auth=("username", token), json=payload)
print r.json()
