# `Worldpay.NetworkPaymentTokens`
[🔗](https://github.com/iamkanishka/worldpay/blob/v1.0.0/lib/worldpay/access/token_services.ex#L1)

Worldpay **Network Payment Token (NPT) API** — manages network payment tokens
that can be used across Worldpay and other acquirers.

Network tokens are format-preserving 16-digit tokens issued by Visa or
Mastercard. Unlike Worldpay tokens (which are Worldpay-specific), NPTs
can be used with any acquirer that supports network tokenization.

This module covers:
- NPT provisioning, inquiry, update, deletion
- Cryptogram provisioning per CIT
- paymentAccountReference (PAR) support
- Multi-acquirer portability

# `delete`

```elixir
@spec delete(String.t(), Worldpay.Config.t()) ::
  {:ok, nil} | {:error, Worldpay.Error.t()}
```

Delete a network token.

# `get`

```elixir
@spec get(String.t(), Worldpay.Config.t()) ::
  {:ok, map()} | {:error, Worldpay.Error.t()}
```

Retrieve a network token.

# `provision`

```elixir
@spec provision(map(), Worldpay.Config.t()) ::
  {:ok, map()} | {:error, Worldpay.Error.t()}
```

Provision a new network token (Visa or Mastercard).

# `provision_cryptogram`

```elixir
@spec provision_cryptogram(String.t(), Worldpay.Config.t()) ::
  {:ok, map()} | {:error, Worldpay.Error.t()}
```

Provision a cryptogram for a CIT using a network token.

Each CIT requires a fresh cryptogram. The cryptogram is single-use
and expires within minutes.

# `update`

```elixir
@spec update(String.t(), map(), Worldpay.Config.t()) ::
  {:ok, map()} | {:error, Worldpay.Error.t()}
```

Update a network token (e.g. update status).
