Use Lithic to build a virtual credit card issuing platform with shared limit

Original link:

After Privacy completed the virtual credit card product for individual users, he found that he was fully capable of making the same product as Marqeta, so Lithic.

Lithic currently offers two card heads: 531367 and 539406, both of which are MasterCard virtual cards.

Before sharing the limit, a new trend in the virtual credit card industry? No, it has always been so. As mentioned, in order to realize the shared quota, the third-party card issuing platform must participate in the processing of the transaction, and Lithic provides this function: Auth Stream Access (ASA) . After enabling this function, Lithic only makes the most basic judgments: whether the card number, CVV, and expiration time are correct. If the above information is correct, it will be handed over to the third-party card issuing platform for the next judgment, otherwise the transaction will be rejected directly. Through this function, third-party card issuing platforms can have more flexible control over cards, such as:

  1. Limit the amount you can spend
  2. Limit Consumable Merchants (Industry)
  3. AVS verification is exempted, that is, the user can freely specify the address and zip code when opening the card

That is, the third-party card issuing platform can independently decide whether to release a certain transaction, which is very convenient. With ASA, it is simple to develop virtual cards with single card model and shared account balance model. Combined with Transaction Webhooks to display transaction records in real time, you are the next Divvy or Bento.

Because software development capability is Lithic’s proud capital, Lithic’s API documentation is easy to understand, and you can get started in minutes. Lithic not only provides a sandbox, but also displays the corresponding GET and POST request records in real time. Developers can’t find an excuse to fish.

In just a few minutes, you can experience operations such as opening a card, setting a card limit, and simulating transactions. Interested students can try it immediately. Open Lithic official homepage: , click “Get Started”, and register a new account.
