It supports secure data handling via encryption, enforces authorization for updates, and enables retrieval of transfer limits, links, and transaction details. External accounts API allows partners access to some money movement capabilities for an end customer without the need for creating or enrolling them into a Green Dot account first. This allows partners who want to use Green Dot services but have customers who don't need a Green Dot account - they can still use those services via the below APIs. Customer doesn't have a BaaS account - a BaaS Partner's customer who doesn't have a BaaS Account at Green Dot. Want to provide a service to their customers without a BaaS Account. Can work on language for this but is used by seeveral partners. Don't have any interest in being a Green Dot customer. Services offered by Green Dot still though. ## Key Implementation Notes * All sensitive profile, bank, and card data is exchanged in encrypted form. * Updates and deletions require prior authorization and a valid customerToken or linkId. * Verification is mandatory after customer creation before transactions can occur. Click the links in the API titles to lead to their respective API reference with full details. # Customer Profile Management Endpoints ## [Create a new customer profile in the Green Dot system.](https://developer.greendot.com/embedded-finance/reference/externalaccount_post_createcustomerprofile) `POST /programs/{programCode}/externalAccounts/customers` This API creates a customer profile.
