# Overview

> Connect Lago to any payment providers by using native integrations or webhook messages.

Lago helps you monitor usage and calculates how much each customer owes you. However, **Lago is not a payment service provider (PSP)**.

## Payment collection process

To collect payments from your customers, you can:

* Use our native integrations with [GoCardless](/guide/payments/gocardless-integration), [Stripe Payments](/guide/payments/stripe-integration) or [Adyen](/guide/payments/adyen-integration); or
* Use the [webhooks](/api-reference/webhooks/messages) sent by Lago to transmit billing information to your PSP (e.g. Paddle, Razorpay, Authorize.net, internal ledger, etc.).

Lago is **agnostic**, which means that you can use our billing solution with any PSP.

## Payment status

When payments are processed through one of our native integrations, the payment status of the invoice is **automatically updated**.

  <Tab title="Dashboard">
    If needed, you can update the payment status via the user interface:

    1. Access the **"Invoices"** section;
    2. Select an invoice from the list;
    3. Open the **"Actions"** dropdown menu in the upper right corner;
    4. Click **"Update payment status"**;
    5. Select the new payment status; and
    6. Click **"Update status"** to confirm.
  </Tab>

  <Tab title="API">
    This action can be performed [via the API](/api-reference/invoices/update) as well by changing the `payment_status` argument.

    ```bash Update a payment status of an invoice
    LAGO_URL="https://api.getlago.com"
    API_KEY="__YOUR_API_KEY__"

    curl --location --request PUT "$LAGO_URL/api/v1/invoices/{__INVOICE_ID__}" \
    --header "Authorization: Bearer $API_KEY" \
    --header 'Content-Type: application/json' \
    --data-raw '{
      "invoice": {
        "payment_status": "succeeded",
        "metadata": [
          {...}
        ]
      }
    }'
    ```
  </Tab>
</Tabs>

## Handling one-off payments

Lago offers a streamlined solution for handling exceptional payment situations through its one-off payment checkout feature.
This is particularly useful when automatic payment processes face issues, resulting in invoices with `pending` or `failed` statuses.

* **Instant checkout link generation:**
  For any troubled invoice, Lago enables you to generate a unique checkout link. This link can be shared with the user to facilitate an immediate payment of that invoice.

* **Automatic payment method storage:**
  Lago captures and stores the payment method used in the one-off transaction. This ensures that future payments are processed more smoothly.

* **Real-time payment status update:**
  The status of the invoice is updated in real time once the payment is successfully processed.

<Info>
  Currently, this feature is only supported for Adyen and Stripe native integrations with Lago.
