[🔗](https://github.com/jeffhuen/tiger_stripe/blob/main/lib/stripe/params/source_create_params.ex#L61)

Nested parameters.

# `t`

```elixir
@type t() :: %Stripe.Params.SourceCreateParams.Mandate{
  acceptance: Stripe.Params.SourceCreateParams.Mandate.Acceptance.t() | nil,
  amount: map() | nil,
  currency: String.t() | nil,
  interval: String.t() | nil,
  notification_method: String.t() | nil
}
```

* `acceptance` - The parameters required to notify Stripe of a mandate acceptance or refusal by the customer.
* `amount` - The amount specified by the mandate. (Leave null for a mandate covering all amounts)
* `currency` - The currency specified by the mandate. (Must match `currency` of the source) Format: ISO 4217 currency code.
* `interval` - The interval of debits permitted by the mandate. Either `one_time` (just permitting a single debit), `scheduled` (with debits on an agreed schedule or for clearly-defined events), or `variable`(for debits with any frequency) Possible values: `one_time`, `scheduled`, `variable`. Max length: 5000.
* `notification_method` - The method Stripe should use to notify the customer of upcoming debit instructions and/or mandate confirmation as required by the underlying debit network. Either `email` (an email is sent directly to the customer), `manual` (a `source.mandate_notification` event is sent to your webhooks endpoint and you should handle the notification) or `none` (the underlying debit network does not require any notification). Possible values: `deprecated_none`, `email`, `manual`, `none`, `stripe_email`. Max length: 5000.
