Link Customer to Loan

This request allows you to link a customer to a loan.


Loans and customers are "linked" when they become associated with each other. Here's what you need to know about linking loans and customers:

  • This request is sent through the Loans endpoint. Thus, the Customers object is included in the payload.
  • Both loans and customers can be created without being associated to each other.
  • Similar to the UI, you can link multiple customers to a loan in a single request.
  • Like we've mentioned in other requests, many users tend to want to simultaneously link a customer when they create a new loan within one request. If this is the case for you, you will need to create a new customer first. Here's why:

    When you create a new loan and link a customer all within the same request, you send it through the Loans endpoint. Therefore, you will need a valid customer ID since you can't create a customer through the Loans endpoint.

    For information on how to simultaneously link a customer while creating a new loan, take a look at our Create New Loan request.

And for an example of how linking works within the UI, read our Link a Customer to a Loan article.
