Setup payment method and checkout later

This solution makes sense if you require your customers to provide a payment method upfront (to be charged later). This solution also makes sense if you are just looking to collect updated payment information for an existing active customer.

Install and import our client

For this recipe, we will use the Python SDK, which you can install using pip install getopenpay or poetry add getopenpay":

from getopenpay.client import ApiKeys, OpenPayClient

OP_PUBLISHABLE_TOKEN = 'TODO_YOUR_PUBLISHABLE_TOKEN'
OP_SECRET_TOKEN = 'TODO_YOUR_SECRET_TOKEN'

api_keys = ApiKeys(publishable_key=OP_PUBLISHABLE_TOKEN, secret_key=OP_SECRET_TOKEN)

# sandbox/staging environment
sandbox_host = 'https://connto.openpaystaging.com'

# production environment
production_host = 'https://connto.getopenpay.com'

client = OpenPayClient(api_keys=api_keys, host=sandbox_host)

Create customer 

create_customer_request = CreateCustomerRequest(
  email='test_customer+1@getopenpay.com',
  first_name='John',
  last_name='Smith',
  line1='123 Main St',
  city='San Francisco',
  state='CA',
  country='US',
  zip_code='94105'
)
customer_external = op_client.customers.create_customer(
  create_customer_request=create_customer_request.to_dict()
)

Create a checkout session

Create a CheckoutSession withSETUP mode

checkout = op_client.checkout.create_checkout_session(
    CreateCheckoutSessionRequest(
      customer_id=customer_id,   # <- pass in cutomser_id
      mode=CheckoutMode.SETUP,
      success_url='https://youapp.com/success-callback',
    )
)

Reroute to our hosted page 

print(f'Reroute customer to this page for payment: {checkout_session.url})

Handle success callback

Verify customer and payment method

# handle success callback
@router.get('/success-callback')
def success_callback(request: Request):
  query_params = request.query_params
  secure_token = query_params.get('secure_token')
  payment_method_id = query_params.get('payment_method_id')

  checkout_session = op_client.checkout.verify_checkout_session_payment_method(
      checkout_secure_token=secure_token,
      payment_method_id=payment_method_id,
  )
  if checkout_session:
    # (Optional) continue for authorization/charging
