Gravv lets you instantly issue virtual payment cards, each powered by stablecoin balances. Gravv-issued cards are linked directly to a single account.

> 📘 Do I create a card directly, like an account?
>
> No. Unlike accounts, a card can't be created directly. Every card needs an **approved card application** first, and in production you create that application by activating the card feature, not by calling Create card. The flow below walks through it, and [Create a card application](/platform/cards/create-a-card-application) covers the application step in detail.

## Card workflow

To issue and manage cards with Gravv:

1. Create a Card Account on your [Dashboard](https://app.gravv.xyz). In the Sandbox environment, select Ethereum as the blockchain network backing the account. In the Live environment, select Polygon.

> 📘 Note
>
> This is a one-time setup that backs the cards you create for your customers. Use an account and network supported by the card feature requirements returned for your customer; your configured card program determines the available options.

2. Save the account ID in your environment variables.

> 📘 Note
>
> You'll pass this account ID as `account_id` in `provider_data` when you activate the card feature in step 6. If you leave it out, Gravv uses your tenant's card account.

3. Create a customer to obtain a customer id.
4. Complete intermediate [Know Your Customer (KYC)](/getting-started/know-your-customer) verification. Intermediate KYC includes a selfie (liveness) check, which cards require.
5. Check the customer's eligibility for the card feature using the [Check feature eligibility](/api-reference/features/post-v1-risk-features-eligibility) endpoint with `feature_id` `virtual_cards`.
6. If the customer is eligible, activate the card feature using the [Activate feature](/api-reference/features/post-v1-risk-features-activate) endpoint. **Activating `virtual_cards` creates the card application** and returns its `application_id`. If the customer still needs a liveness check, the response returns a `websdk_url`. See [Create a card application](/platform/cards/create-a-card-application).
7. Wait to receive the application status via webhook, or check it using the [Get card application](/api-reference/cards/get-v1-cards-applications-application-id) endpoint. For card webhook responses, see [Card events](/platform/webhooks/card-events).
8. Once the application status is `approved`, [create the card](/platform/cards/create-a-card).
9. Retrieve the card details to share with your customer.
10. Fund the card using the [Transfer](/api-reference/transfer/post-v1-transfer) endpoint. For more on funding, see [Fund cards](/platform/cards/fund-cards).
11. Withdraw funds from the card when needed.

## Using cards

Once you create a card for your customer, they can use it immediately for online transactions.

To use the card, enter the card details at checkout:

* Card number
* Expiry date
* CVV
* Billing address
