Plaid Get details of an institution

Returns a JSON response containing details on a specified financial institution currently supported by Plaid. Versioning note: API versions 2019-05-29 and earlier allow use of the `public_key` parameter instead of the `client_id` and `secret` to authenticate to this endpoint. The `public_key` has been deprecated; all customers are encouraged to use `client_id` and `secret` instead.
