Note: As of July 2020, the `/item/public_token/create` endpoint is deprecated. Instead, use `/link/token/create` with an `access_token` to create a Link token for use with [update mode](https://plaid.com/docs/link/update-mode). If you need your user to take action to restore or resolve an error associated with an Item, generate a public token with the `/item/public_token/create` endpoint and then initialize Link with that `public_token`. A `public_token` is one-time use and expires after 30 minutes. You use a `public_token` to initialize Link in [update mode](https://plaid.com/docs/link/update-mode) for a particular Item. You can generate a `public_token` for an Item even if you did not use Link to create the Item originally. The `/item/public_token/create` endpoint is **not** used to create your initial `public_token`. If you have not already received an `access_token` for a specific Item, use Link to obtain your `public_token` instead. See the [Quickstart](https://plaid.com/docs/quickstart) for more information.
