# FAQ

## Getting Started

<AccordionGroup>
  <Accordion title="What is Grid and who is it for?">
    Grid is a low-level payment infrastructure API that enables businesses, financial institutions, and developers to send and receive payments globally across fiat currencies, stablecoins, and Bitcoin.

    Grid is ideal for:

    * Fintech companies building payment products
    * Businesses sending international payouts
    * Platforms enabling P2P payments
    * Companies offering crypto on/off-ramps
    * Businesses distributing rewards or incentives
  </Accordion>

  <Accordion title="How do I get started with Grid?">
    <Steps>
      <Step title="Create an Account">
        Go to [app.lightspark.com](https://app.lightspark.com) to create your account and access the Grid dashboard.
      </Step>

      <Step title="Generate Sandbox API Keys">
        Generate your sandbox API keys from the dashboard and start building and testing your integration.
      </Step>

      <Step title="Go to Production">
        Once testing is complete, reach out to your Lightspark contact to receive production credentials and launch with real transactions.
      </Step>
    </Steps>
  </Accordion>

  <Accordion title="Do I need to know about cryptocurrency to use Grid?">
    No. Grid handles all on-chain operations, wallet management, and crypto conversions behind the scenes. You interact with a simple REST API using familiar concepts like customers, accounts, and transactions. Bitcoin and stablecoins are just another payment rail that Grid manages for you automatically.

## Building your integration

<AccordionGroup>
  <Accordion title="Can I test without moving real money?">
    Yes. The sandbox lets you test your integration without making real payments. Use sandbox API credentials and the simulation tools to exercise payment outcomes before going live. See [sandbox testing](/api-reference/sandbox-testing).
  </Accordion>

  <Accordion title="Do sandbox and production use different APIs?">
    They use the same base URL. Your API token determines which environment a request uses. Production access is arranged with your Lightspark contact after testing. See [environments](/api-reference/environments).
  </Accordion>

  <Accordion title="Which currencies and payment rails can I use?">
    Check [currencies and payment rails](/platform-overview/core-concepts/currencies-and-rails) for coverage. Your platform's configuration determines which currencies are enabled for your integration. Use `GET /config` to check your supported currencies and their customer information requirements.
  </Accordion>

  <Accordion title="How do I know whether a payment has completed?">
    Use webhooks to receive payment status changes, and retrieve the transaction when you need its current state. Verify webhook signatures and handle duplicate events using the event ID. See the [transaction lifecycle](/platform-overview/core-concepts/transaction-lifecycle) and [webhook guide](/api-reference/webhooks).
  </Accordion>

  <Accordion title="Can I start issuing cards as soon as I have API credentials?">
    Cards must be enabled for your platform, and you need to complete card-issuer onboarding before launching. The [implementation overview](/cards/onboarding/implementation-overview) covers the setup and prerequisites.

## Licensing and customer verification

<AccordionGroup>
  <Accordion title="Is Lightspark licensed?">
    Yes. Lightspark's regulated entities hold licenses for financial services, including money transmission in the US and electronic money and crypto-asset services in Europe. See the [licenses page](https://www.lightspark.com/licenses) for the entities, jurisdictions, and licenses. Coverage depends on the service and where you operate; [contact our team](https://www.lightspark.com/contact) to discuss your setup.
  </Accordion>

  <Accordion title="Who handles customer verification?">
    It depends on your platform's setup. Lightspark provides hosted and API-based KYC/KYB flows for platforms that rely on Lightspark for verification. Regulated platforms follow a separate onboarding path. Requirements vary by customer type, region, and currency. See [customer configuration](/payouts-and-b2b/onboarding/configuring-customers) for both paths and the information to collect.
