<Accordion title="Why can't I see Apple Pay or Google Pay as payment method option on xPay?">
  xPay automatically detects whether a customer’s device supports Apple Pay or Google Pay and displays those options in real time. Both Apple Pay and Google Pay are device-specific payment methods, since the card details are securely stored on the customer’s device.\
  \
  If you're expecting to see Apple Pay but don't, make sure you're opening the payment link on an iOS device with a VPN set to a country where apple pay is support (eg. USA) and have apple wallet app set up correctly. Apple Pay is not supported in India.\
  \
  Similar to above, If you're expecting to see Google Pay but don't, make sure you're opening the payment link on an Android device with a US VPN and have Google Pay app set up correctly.

  <Note>
    Google Pay in India is different from Google Pay used internationally. In India, it functions as a UPI app, while outside India it works as a digital wallet for cards.

<Accordion title="Does using Apple pay require any whitelisting from my end?">

## **Tech FAQs**

<Accordion title="How and where do I use the xPay Keys?">
  We follow Basic Auth RFC for authentication.

  In basic HTTP authentication, a request contains a header field in the form of `Authorization: Basic <credentials>`, where `<credentials>` is the [Base64](https://en.wikipedia.org/wiki/Base64) encoding of `<xPay Public Key>` and `<xPay Private Key>` joined by a single colon `:`.

  For a detailed explanation of how to use xPay keys, refer to the [Authentication Page](/developer-resources/authentication).
</Accordion>

<Accordion title="What value do I use in the amount field in API calls?">
  All values in the `amount` field must be in the smallest currency unit. For
  example: - If the transaction is in USD, 1 USD = 100 cents, so to charge USD
  2, you should set the amount to 200. - Similarly, for EUR, 1 EUR = 100 cents.
</Accordion>

<Accordion title="What do I do if I receive a 400 Bad Request response?">
  A 400 Bad Request error usually means there’s something wrong with the request. This can be due to:

  * Incorrect parameters
  * Missing required fields
  * Issues with authentication or malformed data

  Check your API call and ensure all required parameters are correct and properly formatted. Also, verify your xPay API keys and ensure they’re correctly included in the header.

  For a more detailed description of error codes and troubleshooting tips, refer to the [Errors](/developer-resources/errors).
</Accordion>

<Accordion title="How do I integrate xPay with my platform?">
  You can integrate xPay with your platform using our well-documented API. The
  integration process includes authentication, creating a payment intent,
  handling the payment process, and confirming the payment. Refer to the [API
  Integration Guide](/products/one-time-payments/architecture) for step-by-step details.
</Accordion>
