Using the OAuthClient

Example showing how tokens can be obtained, stored and refreshed using the OAuthClient.

In this example a basic dictionary is used as store, which offers no persistence, meaning that OAuthClient.generate_token will be called every time this code executes, which introduces an overhead. The store here could be a database table, file, session or whatever you want.

import pysnow

store = {'token': None}

# Takes care of refreshing the token storage if needed
def updater(new_token):
    print("OAuth token refreshed!")
    store['token'] = new_token

# Create the OAuthClient with the ServiceNow provided `client_id` and `client_secret`, and a `token_updater`
# function which takes care of refreshing local token storage.
s = pysnow.OAuthClient(client_id='<client_id_from_servicenow>',
                       client_secret='<client_secret_from_servicenow>',
                       token_updater=updater, instance='<instance_name>')

if not store['token']:
    # No previous token exists. Generate new.
    store['token'] = s.generate_token('<username>', '<password>')

# Set the access / refresh tokens
s.set_token(store['token'])

# We should now be good to go. Let's define a `Resource` for the incident API.
incident_resource = s.resource(api_path='/table/incident')

# Fetch the first record in the response
record = incident_resource.get(stream=True).first()

# Print it
print(record)
