# `Stripe.Params.V2.Core.AccountLinkCreateParams.UseCase.AccountOnboarding`
[🔗](https://github.com/jeffhuen/tiger_stripe/blob/main/lib/stripe/params/v2/core/account_link_create_params.ex#L31)

Nested parameters.

# `t`

```elixir
@type t() :: %Stripe.Params.V2.Core.AccountLinkCreateParams.UseCase.AccountOnboarding{
  collection_options:
    Stripe.Params.V2.Core.AccountLinkCreateParams.UseCase.AccountOnboarding.CollectionOptions.t()
    | nil,
  configurations: [String.t()] | nil,
  refresh_url: String.t() | nil,
  return_url: String.t() | nil
}
```

* `collection_options` - Specifies the requirements that Stripe collects from v2/core/accounts in the Onboarding flow.
* `configurations` - Open Enum. A v2/core/account can be configured to enable certain functionality. The configuration param targets the v2/core/account_link to collect information for the specified v2/core/account configuration/s.
* `refresh_url` - The URL the user will be redirected to if the AccountLink is expired, has been used, or is otherwise invalid. The URL you specify should attempt to generate a new AccountLink with the same parameters used to create the original AccountLink, then redirect the user to the new AccountLink’s URL so they can continue the flow. If a new AccountLink cannot be generated or the redirect fails you should display a useful error to the user. Please make sure to implement authentication before redirecting the user in case this URL is leaked to a third party.
* `return_url` - The URL that the user will be redirected to upon completing the linked flow.
