I'm integrating bluesnap's payment API with my website. How do I store the card information in bluesnap so that I don't have to do it in my own database?
If you are using the Payment API, you can save credit card data at the shopper level. To do this, you create a saved shopper in BlueSnap and include the card data for that shopper. You can also include information like the shopper's name and address.
For example:
<vaulted-shopper xmlns="http://ws.plimus.com">
<first-name>FirstName</first-name>
<last-name>LastName</last-name>
<payment-sources>
<credit-card-info>
<credit-card>
<card-number>4263982640269299</card-number>
<security-code>837</security-code>
<expiration-month>02</expiration-month>
<expiration-year>2018</expiration-year>
</credit-card>
<billing-contact-info>
<first-name>billingFirstName</first-name>
<last-name>billingLastName</last-name>
<country>US</country>
<state>MA</state>
<address1>10 Main St</address1>
<address2>Apt 1</address2>
<email>email@example.com</email>
<zip>01752</zip>
</billing-contact-info>
</credit-card-info>
</payment-sources>
</vaulted-shopper>
