Customers must complete identity verification before processing conversions. The required information varies based on your platform's regulatory status.

<AccordionGroup>
  <Accordion title="Regulated Platforms" icon="">
    <Check>
      **Regulated platforms** have lighter KYC requirements since they handle compliance verification internally.
    </Check>

    The KYC/KYB flow allows you to onboard customers through direct API calls.

    Regulated financial institutions can:

    * **Direct API Onboarding**: Create customers directly via API calls with minimal verification
    * **Internal KYC/KYB**: Handle identity verification through your own compliance systems
    * **Reduced Documentation**: Only provide essential customer information required by your payment counterparty or service provider.
    * **Faster Onboarding**: Streamlined process for known, verified customers

    #### Creating Customers via Direct API

    For regulated platforms, you can create customers directly through the API without requiring external KYC verification:

    To register a new customer in the system, use the `POST /customers` endpoint:

    ```bash theme={null}
    curl -X POST "https://api.lightspark.com/grid/2025-10-13/customers" \
      -H "Authorization: Basic $GRID_CLIENT_ID:$GRID_CLIENT_SECRET" \
      -H "Content-Type: application/json" \
      -d '{
        "platformCustomerId": "customer_12345",
        "customerType": "INDIVIDUAL",
        "fullName": "Jane Doe",
        "birthDate": "1992-03-25",
        "nationality": "US",
        "address": {
          "line1": "123 Pine Street",
          "city": "Seattle",
          "state": "WA",
          "postalCode": "98101",
          "country": "US"
        }
      }'
    ```

    The examples below show a more comprehensive set of data. Not all fields are strictly required by the API for customer creation itself, but become necessary based on currency and UMA provider requirements if using UMA.

  <Accordion title="Unregulated Platforms" icon="">
    <Warning>
      **Unregulated platforms** require full KYC/KYB verification of customers through hosted flows.
    </Warning>

    Unregulated platforms must:

    * **Hosted KYC Flow**: Use the hosted KYC link for complete identity verification
    * **Extended Review**: Customers may require manual review and approval in some cases

    ### Hosted KYC Link Flow

    The hosted KYC flow provides a secure, hosted interface where customers can complete their identity verification and onboarding process.

    The flow is two steps: create the customer with the information you have, then generate a hosted KYC link for that customer. The customer's `kycStatus` stays `PENDING` until they complete the hosted flow.

    #### 1. Create the customer

    Create the customer with `POST /customers`, supplying at least `customerType` and any fields you already have. See [Configuring Customers](/payouts-and-b2b/onboarding/configuring-customers) for the full list of optional pre-fill fields.

    ```bash theme={null}
    curl -X POST "https://api.lightspark.com/grid/2025-10-13/customers" \
      -u "$GRID_CLIENT_ID:$GRID_CLIENT_SECRET" \
      -H "Content-Type: application/json" \
      -d '{
        "customerType": "INDIVIDUAL",
        "platformCustomerId": "9f84e0c2a72c4fa",
        "region": "US",
        "currencies": ["USD", "USDC"],
        "email": "jane.doe@example.com",
        "fullName": "Jane Doe"
      }'
    ```

    Persist the returned `id` (the Grid customer ID) — you'll need it for the next step.

    #### 2. Generate a KYC link

    ```bash theme={null}
    curl -X POST "https://api.lightspark.com/grid/2025-10-13/customers/Customer:019542f5-b3e7-1d02-0000-000000000001/kyc-link" \
      -u "$GRID_CLIENT_ID:$GRID_CLIENT_SECRET" \
      -H "Content-Type: application/json" \
      -H "Idempotency-Key: $(uuidgen)" \
      -d '{
        "redirectUri": "https://yourapp.com/onboarding-complete"
      }'
    ```

    **Response:**

    ```json theme={null}
    {
      "kycUrl": "https://kyc.lightspark.com/onboard/abc123def456",
      "expiresAt": "2027-01-15T14:32:00Z",
      "provider": "SUMSUB",
      "token": "_act-sbx-jwt-eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
    }
    ```

    <Tip>
      The response always includes `kycUrl` for the hosted flow. For providers that support direct SDK integration (currently SUMSUB), a `token` is also returned — you can pass this to the provider's web SDK to embed verification in your own UI instead of redirecting. Both paths update the customer's `kycStatus` identically.
    </Tip>

    #### Complete KYC Process

    <Steps>
      <Step title="Create the customer">
        Call `POST /customers` with `customerType` and any pre-fill fields you have. The returned `id` is the customer's Grid ID; their `kycStatus` is `PENDING` until verification completes.
      </Step>

      <Step title="Generate the KYC link">
        Call `POST /customers/{customerId}/kyc-link`. Each call returns a fresh single-use `kycUrl` and `expiresAt`; previously-issued links remain single-use but aren't invalidated.

        <Note>
          The `redirectUri` you pass is embedded in the generated `kycUrl` and is used to automatically return the customer to your application after they complete verification.
        </Note>
      </Step>

      <Step title="Send the customer through verification">
        Redirect the customer to `kycUrl`, or — if you want to embed the flow directly — initialize the provider's SDK with the returned `token`.

        <Warning>
          The hosted URL is single-use and expires at `expiresAt`. If a customer needs to retry, call the endpoint again to generate a new link.
        </Warning>
      </Step>

      <Step title="Track the decision">
        Reaching your `redirectUri` only means the customer **finished the hosted flow** — not that they were approved. Wait for the final decision in one of two ways:

        * **Webhook (recommended):** Subscribe to `KYC_STATUS` to be notified when the customer reaches a terminal status (`APPROVED`, `REJECTED`, `EXPIRED`, or `CANCELED`).
        * **Polling:** Call `GET /customers/{customerId}` and inspect `kycStatus`.
      </Step>

      <Step title="Handle completion">
        On `APPROVED`, the customer is ready to transact — proceed with account setup and unlock funding. On `REJECTED` or `EXPIRED`, surface the appropriate next step (for example, regenerate the link or request manual review).
      </Step>
    </Steps>
  </Accordion>
</AccordionGroup>

## Monitor verification status

After a customer completes the KYC/KYB verification process, you'll receive webhook notifications about their KYC status. These notifications are sent to your configured webhook endpoint.

<Note>
  For regulated platforms, customers are created with `APPROVED` KYC status by default.
</Note>

**Webhook Payload (sent to your endpoint):**

```json theme={null}
{
  "id": "Webhook:019542f5-b3e7-1d02-0000-000000000020",
  "type": "CUSTOMER.KYC_APPROVED",
  "timestamp": "2025-07-21T17:32:28Z",
  "data": {
    "id": "Customer:019542f5-b3e7-1d02-0000-000000000001",
    "platformCustomerId": "9f84e0c2a72c4fa",
    "customerType": "INDIVIDUAL",
    "umaAddress": "$john.doe@uma.domain.com",
    "kycStatus": "APPROVED",
    "fullName": "John Michael Doe",
    "birthDate": "1990-01-15",
    "nationality": "US",
    "address": {
      "line1": "123 Main Street",
      "line2": "Apt 4B",
      "city": "San Francisco",
      "state": "CA",
      "postalCode": "94105",
      "country": "US"
    },
    "createdAt": "2025-07-21T17:32:28Z",
    "updatedAt": "2025-07-21T17:32:28Z",
    "isDeleted": false
  }
}
```

**Webhook Headers:**

* `Content-Type: application/json`
* `X-Grid-Signature: {"v": "1", "s": "base64_signature..."}`

<ResponseField name="id" type="string" required>
  Unique identifier for this webhook delivery. Use this for idempotency to prevent processing duplicate webhooks.
</ResponseField>

<ResponseField name="type" type="string" required>
  Status-specific event type. KYC webhooks use `CUSTOMER.*` types:

  * `CUSTOMER.KYC_APPROVED`: Customer verification completed successfully
  * `CUSTOMER.KYC_REJECTED`: Customer verification was rejected
  * `CUSTOMER.KYC_SUBMITTED`: KYC verification was initially submitted
  * `CUSTOMER.KYC_MANUALLY_APPROVED`: Customer was manually approved by platform
  * `CUSTOMER.KYC_MANUALLY_REJECTED`: Customer was manually rejected by platform
</ResponseField>

<ResponseField name="data" type="object" required>
  The full customer resource object, same as the corresponding `GET /customers/{id}` endpoint would return. Includes all customer fields such as `id`, `kycStatus`, `fullName`, `birthDate`, `nationality`, `address`, etc.
</ResponseField>

<Note>
  Intermediate states like `PENDING_REVIEW` do not trigger webhook notifications. Only final resolution states will send webhook notifications.
</Note>

<Accordion title="Webhook Implementation Example">
  ```javascript theme={null}
  // Example webhook handler for KYC status updates
  // Note: Only final states trigger webhook notifications
  app.post('/webhooks/kyc-status', async (req, res) => {
    const { type, data } = req.body;

    switch (type) {
      case 'CUSTOMER.KYC_APPROVED':
        // Activate customer account
        await activateCustomer(data.id);
        await sendWelcomeEmail(data.id);
        break;

      case 'CUSTOMER.KYC_REJECTED':
        // Notify support and customer
        await notifySupport(data.id, 'KYC_REJECTED');
        await sendRejectionEmail(data.id);
        break;

      case 'CUSTOMER.KYC_MANUALLY_APPROVED':
        // Handle manual approval
        await activateCustomer(data.id);
        await sendWelcomeEmail(data.id);
        break;

      case 'CUSTOMER.KYC_MANUALLY_REJECTED':
        // Handle manual rejection
        await notifySupport(data.id, 'KYC_MANUALLY_REJECTED');
        await sendRejectionEmail(data.id);
        break;

      default:
        // Log unexpected types
        console.log(`Unexpected webhook type ${type} for customer ${data.id}`);
    }

    res.status(200).send('OK');
  });
  ```
</Accordion>

<Tip>
  Only customers with `APPROVED` status can create quotes and process
  conversions.
