# Force item(s) for a Sandbox User into an error state

`POST /sandbox/user/reset_login`

`/sandbox/user/reset_login` functions the same as `/sandbox/item/reset_login`, but will modify Items related to a User. This endpoint forces each Item into an `ITEM_LOGIN_REQUIRED` state in order to simulate an Item whose login is no longer valid. This makes it easy to test Link's [update mode](https://plaid.com/docs/link/update-mode) flow in the Sandbox environment.  After calling `/sandbox/user/reset_login`, you can then use Plaid Link update mode to restore Items associated with the User to a good state. An `ITEM_LOGIN_REQUIRED` webhook will also be fired after a call to this endpoint, if one is associated with the Item.
In the Sandbox, Items will transition to an `ITEM_LOGIN_REQUIRED` error state automatically after 30 days, even if this endpoint is not called.

## Request body

- SandboxUserResetLoginRequest — SandboxUserResetLoginRequest defines the request schema for `/sandbox/user/reset_login`
  - `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.
  - `user_token` string — The user token associated with the user for which data is being requested. This field is used only by customers with pre-existing integrations that already use the `user_token` field. All other customers should use the `user_id` instead. For more details, see [New User APIs](https://plaid.com/docs/api/users/user-apis).
  - `item_ids` ItemId[], nullable — An array of `item_id`s associated with the User to be reset. If empty or `null`, this field will default to resetting all Items associated with the User.
  - `user_id` string — A unique user identifier, created by `/user/create`. Integrations that began using `/user/create` after December 10, 2025 use this field to identify a user instead of the `user_token`. For more details, see [New User APIs](https://plaid.com/docs/api/users/user-apis).

## Response `200`

OK

- SandboxUserResetLoginResponse — SandboxUserResetLoginResponse defines the response schema for `/sandbox/user/reset_login`
  - `request_id` string, required — A unique identifier for the request, which can be used for troubleshooting. This identifier, like all Plaid identifiers, is case sensitive.

## Other responses

- `default` — Error response
