This Symphony bot client is written in an event handler architecture. The client keeps polling a datafeed and responds to different types of Real Time Events it receives.
To build a functional bot which responds to different types of incoming messages from datafeed (Connection, IM, Chat Room, etc....), the respective type of listener needs to be implemented by inheriting the interfaces in the listeners folder. Currently ConnectionListener, imListener, RoomListener interfaces are provided.
This client is compatible with Python 3.6 or above
Create a virtual environment by executing the following command (optional):
python -m venv ./venv
Activate the virtual environment (optional):
source ./venv/bin/activate
Install dependencies required for this client by executing the command below.
pip install -r requirements.txt
The Python client operates using a Symphony Service Account, which is a type of account that applications use to work with Symphony APIs. Please contact with Symphony Admin in your company to get the account.
The client currently supports two types of Service Account authentications, they are Client Certificates Authentication and RSA Public/Private Key Pair Authentication.
As an example, the roomListenerTestImp has been implemented to respond with "Hello World", to a chat room in which there is an incoming message. To respond to other types of events, respective Listeners need to be implemented.
RSA Public/Private Key Pair is the recommended authentication mechanism by Symphony, due to its robust security and simplicity.
To run the bot using the RSA Public/Private Key Pair, a rsa_config.json should be provided. In our example, the json file resides in the resources folder but it can be anywhere.
An example main_RSA.py has been provided to illustrate how all components work together.
Notes: Most of the time, the port numbers do not need to be changed.
An example of json has been provided below. (The "botRSAPath" ends with a trailing "/")

"appCertName": "",
"appCertPassword": "",
"proxyURL": "",

}
Adjust the following paths in the sample to match your configuration
- "sym_api_client_python/logs/example.log"
- "sym_api_client_python/resources/config.json"
Example Main Class:
import logging
from sym_api_client_python.configure.configure import SymConfig
from sym_api_client_python.auth.rsa_auth import SymBotRSAAuth
from sym_api_client_python.clients.sym_bot_client import SymBotClient
from sym_api_client_python.listeners.\
im_listener_test_imp import IMListenerTestImp
from sym_api_client_python.listeners.\
room_listener_test_imp import RoomListenerTestImp
def configure_logging():
logging.basicConfig(
filename='sym_api_client_python/logs/example.log',
format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
filemode='w', level=logging.DEBUG
)
logging.getLogger("urllib3").setLevel(logging.WARNING)
def main():
print('Python Client runs using RSA authentication')
# Configure log
configure_logging()
# RSA Auth flow: pass path to rsa_config.json file
configure = SymConfig('sym_api_client_python/resources'
'/rsa_config.json')
configure.load_rsa_config()
auth = SymBotRSAAuth(configure)
auth.authenticate()
# Initialize SymBotClient with auth and configure objects
bot_client = SymBotClient(auth, configure)
# Initialize datafeed service
datafeed_event_service = bot_client.get_datafeed_event_service()
# Initialize listener objects and append them to datafeed_event_service
# Datafeed_event_service polls the datafeed and the event listeners
# respond to the respective types of events
im_listener_test = IMListenerTestImp(bot_client)
datafeed_event_service.add_im_listener(im_listener_test)
room_listener_test = RoomListenerTestImp(bot_client)
datafeed_event_service.add_room_listener(room_listener_test)
# Create and read the datafeed
print('Starting datafeed')
datafeed_event_service.start_datafeed()
if __name__ == "__main__":
main()
To run the bot using the Client Certificates Authentication, a config.json should be provided. In our example, the json file resides in the resources folder but it can be anywhere.
An example main_certificate.py has been provided to illustrate how all components work together.
Notes: Most of the time, the port numbers do not need to be changed.
An example of json has been provided below. (The "botCertPath" ends with a trailing "/")
{
"sessionAuthHost": "MY_ENVIRONMENT-api.symphony.com",
"sessionAuthPort": 443,
"keyAuthHost": "MY_ENVIRONMENT-api.symphony.com",
"keyAuthPort": 443,
"podHost": "MY_ENVIRONMENT.symphony.com",
"podPort": 443,
"agentHost": "MY_ENVIRONMENT.symphony.com",
"agentPort": 443,
"botCertPath": "./sym_api_client_python/resources/certificates/",
"botCertName": "my_bot_cert.p12",
"botCertPassword": "YOUR_PASSWORD",
"botEmailAddress": "YOUR_BOT_EMAIL_ADDRESS",

"appCertName": "",
"appCertPassword": "",
"proxyURL": "",
"proxyPort": 8080,
"proxyUsername": "",
"proxyPassword": "",
"authTokenRefreshPeriod": "30"
}
Once the certificates are provided and example listeners are implemented, let's run the bot by executing following command:
python3 main_certificate.py.
Change the paths to both log, and config.json
- "sym_api_client_python/logs/example.log"
- "sym_api_client_python/resources/config.json"
Example Main Class:
import logging
from sym_api_client_python.configure.configure import SymConfig
from sym_api_client_python.auth.auth import Auth
from sym_api_client_python.clients.sym_bot_client import SymBotClient
from sym_api_client_python.listeners.im_listener_test_imp import \
IMListenerTestImp
from sym_api_client_python.listeners.room_listener_test_imp import \
RoomListenerTestImp
def configure_logging():
logging.basicConfig(

logging.getLogger("urllib3").setLevel(logging.WARNING)
def main():
print('Python Client runs using certificate authentication')
# Configure log
configure_logging()
# Certificate Auth flow: Pass in path to config file
configure = SymConfig('sym_api_client_python/resources/config.json')
configure.load_cert_config()
auth = Auth(configure)
auth.authenticate()
# Initialize SymBotClient with auth and configure objects
bot_client = SymBotClient(auth, configure)
# Initialize datafeed service
datafeed_event_service = bot_client.get_datafeed_event_service()
# Initialize listener objects and append them to datafeed_event_service
# Datafeed_event_service polls the datafeed and the event listeners
# respond to the respective types of events
im_listener_test = IMListenerTestImp(bot_client)
datafeed_event_service.add_im_listener(im_listener_test)
room_listener_test = RoomListenerTestImp(bot_client)
datafeed_event_service.add_room_listener(room_listener_test)
# create data feed and read datafeed continuously in while loop.
print('starting datafeed')
datafeed_event_service.start_datafeed()
if __name__ == "__main__":
main()
The joke bot shows how a Symphony chat bot application works. In general, a chat bot application keeps polling the datafeed API for new messages, then it sends the messages to listeners to handle, depending on the message type.
To interact with the joke bot, try /bot joke
Symphony REST API offer a range of capabilities for application to integrate, visit the official documentation for more information.
- The updates in this release may break your existing bot implementation. Please ensure you review and test against this client prior to deployment in Production.
- Extensively renamed client libraries to follow PEP8 Python standard. Naming now follows "snake_case" convention.
- Bug fixes.
