Python SDK Initialization

Class Initialization sets up the PhonePe Python SDK client using your credentials. This step creates a single client instance that handles all API communications securely throughout the application runtime.

Request

The StandardCheckoutClient class is used to interact with PhonePe APIs. Only one instance of this client should be created per runtime. Make sure to use the correct credentials when initializing to avoid exceptions.

from phonepe.sdk.pg.payments.v2.standard_checkout_client import StandardCheckoutClient
from phonepe.sdk.pg.env import Env
 
client_secret = "<YOUR_CLIENT_SECRET>"
client_id = "<YOUR_CLIENT_ID>"
client_version = <CLIENT_VERSION>  # insert your client version
env = Env.SANDBOX
should_publish_events = False
client = StandardCheckoutClient.get_instance(client_id=client_id,
                                                    client_secret=client_secret,
