Attaching a borrower or guarantor

When creating a loan, you can attach one borrower and one guarantor in the same POST /api/loan request. Use the Borrower_ prefix for a borrower and the Guarantor_ prefix for a guarantor. These fields apply only when creating a loan; contacts cannot be attached or changed with PATCH /api/loan/{id}.

Existing borrower or guarantor

Use Borrower_Id or Guarantor_Id to attach an existing person or company. The ID can be retrieved using Get all borrowers. If the ID is not found, no contact is attached.

{
  "Guarantor_Id": "123456"
}

Individual

Provide the person's name using Borrower_Name or Guarantor_Name. You can also provide Borrower_Email or Guarantor_Email; when an email is provided, both the name and email are used to find an existing individual. If no match is found, a new individual is created.

{
  "Borrower_Name": "Jane Smith",
  "Borrower_Email": "[email protected]"
}

Individual associated with a company

Use Borrower_Company or Guarantor_Company with the individual's name and email. Baseline finds or creates the company, connects the individual to it, and attaches the individual to the loan.

{
  "Borrower_Name": "Jane Smith",
  "Borrower_Email": "[email protected]",
  "Borrower_Company": "Jane Smith Flipping LLC"
}

Company borrower or guarantor

Set Borrower_Is_Company or Guarantor_Is_Company to true and provide the company name. Baseline finds an existing company with that name or creates a new one, then attaches it to the loan.

{
  "Guarantor_Name": "Acme Holdings LLC",
  "Guarantor_Is_Company": true
}
