# `X402.Client.Hooks.Context`
[🔗](https://github.com/cardotrejos/x402/blob/v0.9.0/lib/x402/client/hooks/context.ex#L1)

Context passed between `X402.Client.Hooks` callbacks.

* `:payment_required` — the decoded `PaymentRequired` map the payment is
  built for, or `nil` when `X402.Client.build_payment/3` was given a bare
  requirements map.
* `:requirements` — the selected `accepts` entry. `before_payment/2` may
  replace it; the replacement is what gets signed.
* `:opts` — the validated build options.
* `:payload` — the assembled `PaymentPayload`, set for `after_payment/2`,
  which may replace it.
* `:error` — the failure reason, set for `on_payment_failure/2`, which may
  replace it.

# `t`

```elixir
@type t() :: %X402.Client.Hooks.Context{
  error: term() | nil,
  opts: keyword(),
  payload: map() | nil,
  payment_required: map() | nil,
  requirements: map()
}
```

# `new`
*since 0.9.0* 

```elixir
@spec new(map() | nil, map(), keyword()) :: t()
```

Builds a new client hook context.

## Examples

    iex> requirements = %{"scheme" => "exact", "network" => "eip155:8453"}
    iex> context = X402.Client.Hooks.Context.new(%{"accepts" => [requirements]}, requirements, [])
    iex> context.requirements["scheme"]
    "exact"
    iex> {context.payload, context.error}
    {nil, nil}
