# Create a test Item and processor token

`POST /sandbox/processor_token/create`

Use the `/sandbox/processor_token/create` endpoint to create a valid `processor_token` for an arbitrary institution ID and test credentials. The created `processor_token` corresponds to a new Sandbox Item. You can then use this `processor_token` with the `/processor/` API endpoints in Sandbox. You can also use `/sandbox/processor_token/create` with the [`user_custom` test username](https://plaid.com/docs/sandbox/user-custom) to generate a test account with custom data.

## Request body

- SandboxProcessorTokenCreateRequest — SandboxProcessorTokenCreateRequest defines the request schema for `/sandbox/processor_token/create`
  - `client_id` string — Your Plaid API `client_id`. The `client_id` is required and may be provided either in the `PLAID-CLIENT-ID` header or as part of a request body.
  - `secret` string — Your Plaid API `secret`. The `secret` is required and may be provided either in the `PLAID-SECRET` header or as part of a request body.
  - `institution_id` string, required — The ID of the institution the Item will be associated with
  - `options` SandboxProcessorTokenCreateRequestOptions — An optional set of options to be used when configuring the Item. If specified, must not be `null`.
    - `override_username` string, nullable — Test username to use for the creation of the Sandbox Item. Default value is `user_good`. You can also use a custom test user — either set this to the username of a custom user configured in the Dashboard, or set it to `user_custom` and pass the JSON-stringified custom user configuration object as `override_password` to define one entirely via API. See [Sandbox Custom Users](https://plaid.com/docs/sandbox/user-custom) for more details.
    - `override_password` string, nullable — Test password to use for the creation of the Sandbox Item. Default value is `pass_good`.

See [Sandbox Custom Users](https://plaid.com/docs/sandbox/user-custom) for more details.
