provider plaid POST /sandbox/public_token/create
@utdk/plaid /sandbox/public_token/create
Create a test Item
Use the `/sandbox/public_token/create` endpoint to create a valid `public_token` for an arbitrary institution ID, initial products, and test credentials. The created `public_token` maps to a new Sandbox Item. You can then call `/item/public_token/exchange` to exchange the `public_token` for an `access_token` and perform all API actions. `/sandbox/public_token/create` can also be used with the [`user_custom` test username](https://plaid.com/docs/sandbox/user-custom) to generate a test account with custom data, or with Plaid's [pre-populated Sandbox test accounts](https://plaid.com/docs/sandbox/test-credentials/).

Input

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.

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.

The ID of the institution the Item will be associated with

required

The products to initially pull for the Item. May be any products that the specified `institution_id` supports. This array may not be empty.

An optional set of options to be used when configuring the Item. If specified, must not be `null`.

The user token associated with the User data is being requested for. 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).

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).
