Customers are unique to each Program, and managing all accounts and identifying information is handled on a Program-by-Program basis. The ability to create new Customers is also a preset condition of your Program at Newline. Please see the below sections for more details.## Newline preset-CustomersIn cases where the Client also serves as the Customer (i.e., the Client is both the end-user and the managing entity over any financial products), Newline will create Customers upon Program onboarding. Clients will also be precluded from creating new Customers.## Client-initiated Customers**Customer Onboarding Process for Clients** When managing customer onboarding, follow the outlined steps and key considerations below.### Steps for Onboarding Customers:1. Initial Submission: 1. Submit the external_uid and email using the Customers Endpoint.2. Provide Personally Identifiable Information (PII): 1. After the initial submission, supply the remaining PII for the customer. 2. Ensure that all required PII fields are complete. Requests with complete or missing fields will be accepted.3. Edit PII (Optional): 1. PII can be updated until a valid request is sent to onboard the customer to a product using the Customer Product Endpoint.4. Submit Profile Responses: 1. Provide profile responses to meet the product's profile requirements. 2. Profile Requirements can include data such as: 1. Risk tolerance 2. Income level 3. Other product-specific information5.
