Making Payments

To initiate a payment, use the initialize method. This method requires a set of parameters like the customer's email, amount, first name, last name, and a transaction reference.

    first_name="John",

    tx_ref="your_unique_transaction_reference",
    callback_url="https://yourcallback.url/here"
)
print(response)

Verifying Payments

After initiating a payment, you can verify the transaction status using the verify method.

transaction_id = "your_transaction_id"
verification_response = chapa.verify(transaction_id)
print(verification_response)

Creating Subaccounts

You can create subaccounts for split payments using the create_subaccount method.

subaccount_response = chapa.create_subaccount(
    business_name="My Business",
    account_name="My Business Account",
    bank_code="12345",
    account_number="0012345678",
    split_value="0.2",
    split_type="percentage"
)
print(subaccount_response)

    account_number="0987654321",
    amount="500",
    reference="your_transfer_reference",
    bank_code="67890",
    currency="ETB"
