Accept Lightning Payments From Cash App Users

Yes. Cash App users can send bitcoin over the Lightning Network, and any business that accepts Lightning through the Amboss Payments API can receive those payments directly. Cash App ended 2025 with 59 million monthly actives, per Block's Q4 2025 shareholder remarks, so accepting Lightning turns a large consumer base into people who can pay you, with the rail invisible to the payer.

Does Cash App support Lightning?

Yes, for both sending and receiving. Cash App integrated the Lightning Network so users can move a bitcoin balance in and out of the app near instantly. To pay you, a customer opens the bitcoin tab, scans your Lightning invoice as a QR code, and confirms.

The Cash App Lightning help page describes the feature directly:

Cash App is integrated with the Lightning Network, and you can use Lightning to send and receive bitcoin on Cash App.

There is an important distinction to keep straight. Cash App payments over Lightning are not the same thing as "Cash App Pay", which is a checkout button that debits a Cash App balance or linked card and has no connection to Bitcoin, as the Cash App Pay product page makes clear. Amboss helps you receive the Lightning payments, not the Cash App Pay button.

How do you receive payments from Cash App users?

You do not build a Cash App integration. You accept Lightning once and every Cash App user becomes a potential payer. The flow is four steps:

1. Integrate the Amboss Payments API and create a Lightning invoice for the order amount.
2. Show the invoice to the customer as a QR code or a copyable string at checkout.
3. The customer scans it inside Cash App and confirms the send from their bitcoin balance.
4. The payment routes over Lightning and settles to you in seconds. You fulfill the order.

This is how Cash App payments reach a Lightning-enabled business without the customer ever choosing a "rail" or holding a Bitcoin account with you. Live network capacity and routing data are published on the Amboss Space Lightning explorer.

How do you integrate Cash App receiving into checkout?

Receiving from Cash App is the standard Lightning receive flow: create an invoice, then confirm settlement. A Lightning invoice is a self-contained string defined by the BOLT 11 payment-encoding specification, so the same code path accepts Cash App, Strike, and any other Lightning sender.

The Amboss Payments API is GraphQL. A single create_receive mutation returns the BOLT 11 invoice you show the customer:

mutation CreateReceive {
  payment {
    transaction {
      create_receive(
        input: {
          wallet_id: "your-wallet-id"
          amount: "50000"
          description: "Order #1234"
        }
      ) {
        status
        payment_request
        payment_hash
      }
    }
  }
}

Send it to the https://rails.amboss.tech/graphql endpoint with your x-api-key. The payment_request field is the lnbc... string you render as a QR code, and you confirm settlement with the payment.completed webhook, as documented in the Amboss Payments API documentation. Lightning settles atomically, so there is no pending state that reverses a week later.

Where does Amboss Payments fit?

Lightning is an open standard, which is why a single integration receives from every wallet. The Lightning specification describes it plainly:

a layer-2 protocol for off-chain bitcoin transfer by mutual cooperation, relying on on-chain transactions for enforcement if necessary.

Amboss Payments gives you that integration as a managed API, with no node to operate, so the work of accepting a Cash App customer is the same as accepting anyone else on the Lightning Network. If you want to talk through volume, settlement, or pricing, contact the Amboss team.
