Find out time stamp of Slack message from Python API

I created Slack app, added Bot and Incoming Webhook to it and posted some messages with Bot. Now I would like to find out time stamp of Slack message in order to delete it later with chat.delete method.
I found it that I can use channels.history method.
Here is how I tried to use it. I used it with token found under OAuth Access Token, since per docs I cannot use Bot token with channels.history method.
from slackclient import SlackClient
slack_token_user_token = 'xoxp-long_string_of_integers'
sc_user_token = SlackClient(slack_token_user_token)
sc_user_token.api_call(
"channels.history",
channel="CHXXXXXXX")
I got back the following error:

If this is permission issue, how do I find out proper token to use?

According to the error message you posted the token used is lacking the required scope.
'needed': 'channels:history'
It looks like you provided the bot token, which can not work.
'provided': 'identify,bot,incoming-webhook'
Provide the access token and make sure you first add the channel.history scope and reinstall the app to activate.

Python-Jira create issue giving Screen error

I am using Jira library with Python to create Jira-issue but getting below error:
jira.exceptions.JIRAError: JiraError HTTP 400
text: Field 'Component/s' cannot be set. It is not on the appropriate screen, or unknown.
url: http://jira.corp.inmobi.com/rest/api/2/issue

response text = {"errorMessages":[],"errors":{"Component/s":"Field 'Component/s' cannot be set. It is not on the appropriate screen, or unknown."}}
Could anyone please help me to sort out it?

Jira is complaining about the unexpected backslash in 'Component\s'.
Change it to:
'components: [{'name' : "ABC"}]'
and it should solve your issue (pun intended).

Not able to upload a file through python

After several attempts and repeated failures, I am posting my code excerpt here. I keep getting Authentication failure. Can somebody point out what is it that I am doing wrong here?
import requests
fileToUpload = {'file': open('/home/pinku/Desktop/Test_Upload.odt', 'rb')}
res = requests.post('https://upload.backupgrid.net/add', fileToUpload)
print res.headers
cookie = {'PHPSESSID': 'tobfr5f31voqmtdul11nu6n9q1'}
requests.post('https://upload.backupgrid.net/add', cookie, fileToUpload)
By print res.headers, I get the following:

It contains the cookies also. Am I passing the cookies correctly? Please help!

You are not passing cookies correctly, should be:
requests.post('https://upload.backupgrid.net/add',
files=fileToUpload,
cookies=cookie)

Why is Facebook authentication via Python producing an error?

I am trying to authenticate users of my Django application into Facebook via the oauth2 Python package.
def myView(request):
consumer = oauth2.Consumer(
key = settings.FACEBOOK_APP_ID,
secret = settings.FACEBOOK_APP_SECRET)
# Request token URL for Facebook.
request_token_url = "https://www.facebook.com/dialog/oauth/"
# Create client.
client = oauth2.Client(consumer)
# The OAuth Client request works just like httplib2 for the most part.
resp, content = client.request(request_token_url, "GET")
# Return a response that prints out the Facebook response and content.
return HttpResponse(str(resp) + '\n\n ------ \n\n' + content)
However, I am directed to a page that contains an error when I go to this view. The error has this response from Facebook.

Does anyone see anything awry in my code? I have tried concatenating arguments as strings to request_token_url to no avail. I am sure that my Facebook app ID and secret string are correct.

LinkedIn JS API token exchange to REST token

I am using the Python python-oauth2. I am receiving an error when trying to exchange my tokens. Here is a snippet of the code:
consumer = oauth.Consumer(consumer_key, consumer_secret)
client = oauth.Client(consumer)
client.request(access_token_url, "POST", headers={'xoauth_oauth2_access_token':'XXXXXXXXXX'})
({'status': '400', 'content-length': '83', 'transfer-encoding': 'chunked', 'vary': 'Accept-Encoding', 'server': 'Apache-Coyote/1.1', '-content-encoding': 'gzip', 'date': 'Thu, 10 May 2012 22:28:38 GMT', 'nncoection': 'close', 'content-type': 'application/x-www-form-urlencoded;charset=UTF-8', 'www-authenticate': 'OAuth realm="https%3A%2F%2Fapi.linkedin.com", oauth_problem="parameter_absent", oauth_parameters_absent="oauth_token%26oauth_verifier"'}, 'oauth_problem=parameter_absent&oauth_parameters_absent=oauth_token%26oauth_verifier')
It is getting a 400 response saying:
oauth_problem="parameter_absent", oauth_parameters_absent="oauth_token%26oauth_verifier"
I cannot get an auth_verifier because this is an JSAPI to REST exchange. Is there something different I should be doing for the call?

You don't pass xoauth_oauth2_access_token as a header, but a query parameter.
