braintree not havingt to enter credit card data each time

Question

Asuming that I have a customer registered who already provided his credit card data and I don't want him enter it again on a next purchase, how would I do that? Right now I am using hosted fields and each time when testing I have to enter credit card data.

Answer 1

Ensure the customer's information (including payment method information), is being stored in the Braintree Vault.

You can create a customer by itself, with a payment method, or with a credit card with a billing address. Example of a customer creation;

result = braintree.Customer.create({
  "first_name": "Charity",
  "last_name": "Smith",
  "payment_method_nonce": nonce_from_the_client
})


result.is_success
# True

result.customer.id
# e.g 160923

result.customer.payment_methods[0].token
# e.g f28w39

If you intend to create a transaction at the same time as a customer, you may want to use Transaction.sale() with either the options.store_in_vault_on_success or options.store_in_vault options. For example:

result = braintree.Transaction.sale({
"amount": "10.00",
"payment_method_nonce": nonce_from_the_client,
"customer": {
  "id": "a_customer_id"
},
"options": {
"store_in_vault_on_success": True,
  }
})

Once their information is stored in the Vault, you can pass their payment method token in the transaction API call, rather than a nonce.
