+Before getting started, create a token allowing you to make GraphQL POST requests as a customer. This type of token is the most appropriate for an application that will make server-to-server requests to the GraphQL Storefront API. This guide will use this authentication method. You could create and use a Storefront API Token to authenticate requests to the GraphQL Storefront API if you prefer to use tokens that expire. For more creating a Storefront API Token, see [Create a Token](https://developer.bigcommerce.com/docs/rest-authentication/tokens#create-a-token). 
 
 To generate a [customer impersonation token](/docs/rest-authentication/tokens#customer-impersonation-tokens), send a POST request to `/v3/storefront/api-token-customer-impersonation`.
