# Fulfill a payment request

> Pay a request addressed to you from a wallet or bank account

<Snippet file="shared/prerequisites.mdx" />

<Snippet file="shared/mcp-callout.mdx" />

## See what's waiting on you

List the requests addressed to you with [`GET /payment-requests/incoming`](/api-reference/paymentrequests/list-incoming-payment-requests).

<CodeGroup>
  ```python Python theme={null}
  from naturalpay import Natural

  client = Natural()
  requests = client.payment_requests.list_incoming()
  ```

  ```typescript TypeScript theme={null}
  import Natural from "@naturalpay/sdk";

  const client = new Natural();
  const requests = await client.paymentRequests.listIncoming();
  ```

  ```bash CLI theme={null}
  natural payment-requests listIncoming
  ```

  ```bash cURL theme={null}
  curl https://api.natural.com/payment-requests/incoming \
    -H "Authorization: Bearer $NATURAL_API_KEY"
  ```
</CodeGroup>

<Snippet file="api-examples/paymentRequests.listIncoming.response.mdx" />

Each item's `id` (`prq_*`) is what you fulfill or decline below. A `status` of `OPEN` means it's still waiting on you.

## Fulfill it

[`POST /payment-requests/{paymentRequestId}/fulfill`](/api-reference/paymentrequests/fulfill-payment-request) pays the request and moves the money. The amount comes from the request itself. You only choose where it is paid from, so set `paymentSource` to a wallet you own.

<Snippet file="api-examples/paymentRequests.fulfill.response.mdx" />

Fulfilling returns the resulting **payment** (`pay_*`), which starts in `PROCESSING`. [Track it](/guides/payments/track-payment) to confirm it settles.

<Note>You can also fulfill from a linked bank account instead of a wallet.</Note>

<Snippet file="shared/on-behalf-callout.mdx" />

## Decline it

[`POST /payment-requests/{paymentRequestId}/decline`](/api-reference/paymentrequests/decline-payment-request) turns the request down. No money moves, the requester is notified, and the request's `status` becomes `DECLINED`. Declining is final and cannot be undone.

<CodeGroup>
  ```python Python theme={null}
  import uuid

  declined = client.payment_requests.decline(
      "prq_550e8400e29b41d4a716446655440000",
      idempotency_key=str(uuid.uuid4()),
  )
  ```

  ```typescript TypeScript theme={null}
  const declined = await client.paymentRequests.decline({
    paymentRequestId: "prq_550e8400e29b41d4a716446655440000",
    idempotencyKey: crypto.randomUUID(),
  });
  ```

  ```bash CLI theme={null}
  natural payment-requests decline \
    --payment-request-id prq_550e8400e29b41d4a716446655440000 \
    --idempotency-key "$(uuidgen)"
  ```

  ```text MCP theme={null}
  Decline payment request prq_550e8400e29b41d4a716446655440000.

  ```bash cURL theme={null}
