# Add Virtual Accounts

> Request Virtual Accounts and retrieve deposit instructions

The customer must already be onboarded and active before you add a feature. You get `customerId` from the `application.approved` webhook — see [Onboard a Customer](/guides/onboard-customer) and [The Onboarding Lifecycle](/guides/onboarding-lifecycle). Calling features before the customer is active returns [`CUSTOMER_NOT_ONBOARDED`](/errors/customer-not-onboarded).

<Note>
  **Test this flow in sandbox.** Drive it end-to-end with simulated money and deterministic controls — start with the [sandbox quickstart](/sandbox/quickstart), then [deposit simulation](/sandbox/deposits) for this flow, and the [cheat sheet](/sandbox/cheat-sheet) for every magic value and simulate endpoint.
</Note>

## Flow

Add Virtual Accounts by submitting a feature application against an existing customer. The integration:

1. Discover the customer's feature requirements.
2. Submit a `virtual_account` feature application.
3. Listen for `application.approved` or `application.rejected` webhooks (with `applicationType: "virtual_account"`).
4. Listen for `virtual_account.activated`.
5. Fetch the customer's Virtual Accounts and read `balances[]` plus `depositInstructions[]`.

## Request The Feature

Discover any extra requirements for the customer:

```bash theme={null}
curl 'https://api.conduit.financial/v2/customers/{customerId}/features/requirements?type=virtual_account' \
  -H "x-api-key: YOUR_API_KEY"
```

Like the onboarding flow, the discovery response lists any required `fields` and `documents`. When present, collect them and include them in the submit body below. When the response asks for nothing extra, submit with just `type` and `asset`.

Submit the Virtual Account feature application for the target asset. `Idempotency-Key` is required — without it the call returns `IDEMPOTENCY_KEY_REQUIRED`.

```bash theme={null}
curl https://api.conduit.financial/v2/customers/{customerId}/features \
  -X POST \
  -H "x-api-key: YOUR_API_KEY" \
  -H "content-type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{
    "type": "virtual_account",
    "asset": { "code": "USD" }
  }'
```

The endpoint returns `202 Accepted` with a Virtual Account feature application carrying its own application id. Track it through the `application.approved` and `application.rejected` webhooks with `applicationType: "virtual_account"`.

## Listen For Activation

Once the feature application is approved, listen for `virtual_account.activated` to know the Virtual Account is usable. Deposit instructions populate once the Virtual Account's `status` is `active`. See [Webhooks](/webhooks) and [Virtual Accounts](/concepts/virtual-accounts).

## Retrieve Deposit Instructions

After activation, fetch the Virtual Accounts for the customer:

```bash theme={null}
curl https://api.conduit.financial/v2/customers/{customerId}/virtual-accounts \
  -H "x-api-key: YOUR_API_KEY"
```

The response contains VA-level balances and deposit instructions. It does not include provider bank accounts.

Retrieve one Virtual Account when you have its id:

```bash theme={null}
curl https://api.conduit.financial/v2/customers/{customerId}/virtual-accounts/{virtualAccountId} \
  -H "x-api-key: YOUR_API_KEY"
```
