- RSA Encrypt Data
- Custom – Saved Card
RSA Encrypt Data
This method is used to RSA Encrypt the data with the provided public key.
Parameters
| Parameter | Type | Mandatory | Description |
|---|---|---|---|
| data | str | Yes | The data to encrypt, generally it is the card number or the card cvv. |
| public_key | str | Yes | The public key provided by PhonePe. |
For Python SDK Version **\ 0.0.3**, the imports should be:
from phonepe.sdk.pg.payments.**v1**”
For Python SDK Version <= 0.0.3, the imports should be:
from phonepe.sdk.pg.payments
For Python SDK Version > 0.0.3, the imports should be:
from phonepe.sdk.pg.payments.v1
Example – RSA Encrypt Data
Pythonfrom phonepe.sdk.pg.payments.v1.payment_client import PhonePePaymentClient from phonepe.sdk.pg.env import Env merchant_id = "<YOUR_MERCHANT_ID>" salt_key = "<YOUR_SALT_KEY>" salt_index = 1 # insert your salt index env = Env.UAT should_publish_events = True phonepe_client = PhonePePaymentClient(merchant_id, salt_key, salt_index, env, should_publish_events) sensitive_data = "<CARD_CVV>" public_key = "<YOUR_PUBLIC_KEY>" encrypted_data = phonepe_client.encrypt_data(data=sensitive_data, public_key=public_key)
Returns
The encrypted data.
Custom – Saved Card
This method is used to initiate a Saved Card via the PhonePe PG Custom Checkout
Parameters
| Parameter | Type | Mandatory | Description |
|---|---|---|---|
| merchant_transaction_id | str | Yes | The unique transaction ID assigned by the merchant. Note: – merchantTransactionId length should be less than 35 characters – No Special characters allowed except underscore “_” and hyphen “-“ |
| amount | int | Yes | The amount of the payment. In paise. Minimum 100 i.e. 1 rupee |
| auth_mode | str | Yes | The authentication mode for the card payment. Generally 3DS is used. |
| card_id | bool | Yes | The ID of the saved card. You can find this in the callback from the callback of Card instrument, when save_card=True |
| encrypted_cvv | str | Yes | The encrypted CVV (Card Verification Value) of the card. |
| encryption_key_id | int | Yes | The ID of the encryption key used for encrypting the card details. |
| merchant_user_id | str | No | The ID assigned to the user by the merchant. Note: – merchantUserId length should be less than 36 characters – No Special characters allowed except underscore “_” and hyphen “-“ |
| redirect_url | str | No | The UI URL to redirect the user after a successful payment. |
| redirect_mode | str | No | The mode of redirection after payment completion. |
| callback_url | str | No | The S2S callback URL to which status notifications will be sent. |
| callback_mode | str | No | The mode of callback handling. |
| merchant_order_id | str | No | The ID of the order assigned by the merchant. |
| device_os | str | No | The operating system of the device used for the payment. Possible values: ANDROID or IOS. |
Example (Custom – Saved Card)
Pythonimport uuid from phonepe.sdk.pg.payments.v1.models.request.pg_pay_request import PgPayRequest from phonepe.sdk.pg.payments.v1.payment_client import PhonePePaymentClient from phonepe.sdk.pg.env import Env merchant_id = "<YOUR_MERCHANT_ID>" salt_key = "<YOUR_SALT_KEY>" salt_index = 1 # insert your salt index env = Env.UAT should_publish_events = True phonepe_client = PhonePePaymentClient(merchant_id, salt_key, salt_index, env, should_publish_events) unique_transaction_id = str(uuid.uuid4())[:-2] s2s_callback_url = "https://www.merchant.com/callback" amount = 100 id_assigned_to_user_by_merchant = '<YOUR_USER_ID>' saved_card_id_from_response = "<CARD_ID>" encryption_key_id = 2 # Insert your encryption key id encrypted_cvv = "<ENCRYPTED_CVV>" # can use encrypt_data function saved_card = PgPayRequest.saved_card_pay_request_builder(merchant_transaction_id=unique_transaction_id, amount=amount, auth_mode="3DS", card_id=saved_card_id_from_response, encrypted_cvv=encrypted_cvv, encryption_key_id=encryption_key_id) pay_page_response = phonepe_client.pay(saved_card)
Returns
The pay function returns a PgPayResponse object. With SavedCardInstrumentResponse object in data.
