Cannot close trade successfully with Oanda Api - python

I am using the following code for request:
import requests
import print
import json
api_key = "XXX-XXX"
api_version = 'v3'
accountID = "XXX"
tradeID = "XX"
#Endpoint Parts
api_base_url = f"https://api-fxpractice.oanda.com/"
key_url = f"https://api-fxpractice.oanda.com/v3/accounts"
headers = {
'Authorization': f'bearer {api_key}',
'Content-Type': 'application/json'
}
data = {'units': 'ALL'}
endpoint_path = f"/{api_version}/accounts/{accountID}/trades/{tradeID}/close"
endpoint = f"{api_base_url}{endpoint_path}"
r = requests.put(endpoint, headers=headers, data=data)
print(r.status_code)
pprint.pprint(r.json())
Response I get:
400
{'errorMessage': "Invalid value specified for 'Authorization'"}

OK, your code works for me but with several changes.
It would be helpful to include which JWT you're library; I assume PyJWT
You need to include target_audience
ALG="RS256"
PROJECT=os.getenv("PROJECT")
REGION=os.getenv("REGION")
ACCOUNT=os.getenv("ACCOUNT")
FUNCTION=os.getenv("FUNCTION")
EMAIL="{account}#{project}.iam.gserviceaccount.com".format(
account=ACCOUNT,
project=PROJECT,
)
ROOT="{region}-{project}.cloudfunctions.net".format(
region=REGION,
project=PROJECT,
)
ENDPOINT="https://{root}/{function}".format(

"iss": EMAIL,
"sub": EMAIL,
"exp": time.time()+3600,
"iat": time.time(),
"aud": "https://www.googleapis.com/oauth2/v4/token",
}
NOTE I think exp and iat should be integers but your code works as-is.
The .decode("ascii") appended to jwt.encode().decode("ascii") is incorrect.
The payload should not be URL-encoded:
payload = "grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer&assertion={jwt}".format(
jwt=jwt_token,
)
The /oauth2/v4/token endpoint does not return an access_token per #john-hanley comment. It returns an id_token (as described by Google in the doc you reference).
jwt = data.decode("utf-8")
jwt_list = json.loads(jwt)
id_token=jwt_list["id_token"]
conn = http.client.HTTPSConnection(ROOT)
headers = {
"Authorization": "Bearer {token}".format(token=id_token),
}
conn.request("GET", "/{function}".format(function=FUNCTION), headers=headers)

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.

Trying to retrieve data from the Anbima API

I'm trying to automate a process in which i have to download some brazilian fund quotes from Anbima (Brazil regulator). I have been able to work around the first steps to retrieve the access token but i don't know how to use the token in order to make requests. Here is the tutorial website https://developers.anbima.com.br/en/como-acessar-nossas-apis/.
I have tried a lot of thing but all i get from the request is 'Could not find a required APP in the request, identified by HEADER client_id.'
If someone could share some light. Thank you in advance.
import requests
import base64
import json
requests.get("https://api.anbima.com.br/feed/fundos/v1/fundos")
ClientID = '2Xy1ey11****'
ClientSecret = 'faStF1Hc****'
codeString = ClientID + ":" + ClientSecret
codeStringBytes = codeString.encode('ascii')
base64CodeBytes = base64.b64encode(codeStringBytes)
base64CodeString = base64CodeBytes.decode('ascii')
url = "https://api.anbima.com.br/oauth/access-token"
headers = {
'content-type': 'application/json'
,'authorization': f'Basic {base64CodeString}'
}
body = {
"grant_type": "client_credentials"
}
r = requests.post(url=url, data=json.dumps(body), headers=headers, allow_redirects=True)
jsonDict = r.json()
##################
urlFundos = "https://api-sandbox.anbima.com.br/feed/precos-indices/v1/titulos-publicos/mercado-secundario-TPF"
token = jsonDict['access_token']
headers2 = {
'content-type': 'application/json'
,'authorization': f'Bearer {token}'
}
r2 = requests.get(url=urlFundos, headers=headers2)
r2.status_code
r2.text

I was having the same problem, but today I could advance. I believe you need to adjust some parameters in the header.
Follows the piece of code I developed.
from bs4 import BeautifulSoup
import requests
PRODUCTION_URL = 'https://api.anbima.com.br'
SANDBOX_URL = 'https://api-sandbox.anbima.com.br'
API_URL = '/feed/fundos/v1/fundos/'
CODIGO_FUNDO = '594733'
PRODUCTION = False
if PRODUCTION:
URL = PRODUCTION_URL
else:
URL = SANDBOX_URL
URL = URL + API_URL + CODIGO_FUNDO
HEADER = {'access_token': 'your token',
'client_id' : 'your client ID'}
html = requests.get(URL, headers=HEADER).content
soup = BeautifulSoup(html, 'html.parser')
print(soup.prettify())
The sandbox API will return a dummy JSON. To access the production API you will need to request access (I'm trying to do this just now).

url = 'https://api.anbima.com.br/oauth/access-token'
http = 'https://api-sandbox.anbima.com.br/feed/precos-indices/v1/titulos-publicos/pu-intradiario'
client_id = "oLRa*******"
client_secret = "6U2nefG*****"
client_credentials = "oLRa*******:6U2nefG*****"
client_credentials = client_credentials.encode('ascii')
senhabytes = base64.b64encode(client_credentials)
senha = base64.b64decode(senhabytes)
print(senhabytes, senha)
body = {
"grant_type": "client_credentials"
}
headers = {
'content-type': 'application/json',
'Authorization': 'Basic b0xSYTJFSUlOMWR*********************'
}
request = requests.post(url, headers=headers, json=body, allow_redirects=True)
informacoes = request.json()
token = informacoes['access_token']
headers2 = {
"content-type": "application/json",
"client_id": f"{client_id}",
"access_token": f"{token}"
}
titulos = requests.get(http, headers=headers2)
titulos = fundos.json()
I used your code as a model, then I've made some changes. I've printed the encode client_id:client_secret and then I've copied and pasted in the headers.
I've changed the data for json.

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.
