I'm trying to place API calls to charge shoppers in BlueSnap's Sandbox - using a simple Auth-Capture call and I'm not sure which test cards I can use:
<credit-card>
<card-number>4263982640269299</card-number>
<security-code>837</security-code>
<expiration-month>02</expiration-month>
<expiration-year>2018</expiration-year>
</credit-card>
I'm looking for reference on: 1. Can I just use any test card I find on Google? 2. Can I test card failures somehow? 3. Do online wallets work with the same type of cards?
