Creates a new end customer for a Plaid reseller.

The /partner/customer/create endpoint is used by reseller partners to create end customers. To create end customers, it should be called in the Production environment only, even when creating Sandbox API keys. If called in the Sandbox environment, it will return a sample response, but no customer will be created and the API keys will not be valid.

client_idstring

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.

Important: Data Transparency Messaging (DTM) use cases will not be copied to the end customer's Link customization unless the Publish changes button is clicked after the use cases are applied. Link will not work in Production unless the end customer's DTM use cases are configured. For more details, see Data Transparency Messaging.

A logo is required if create_link_customization is true. If create_link_customization is false and the logo is omitted, the partner's logo will be used if one exists, otherwise a stock logo will be used.
