Application overview

Create and manage a loan application for a customer. An application specifies how much the customer wants to borrow and progresses through various statuses as iwoca assesses it.

Essentials

1. 1
   Set the amount

   Required field, in EUR. The API accepts a wide range, but iwoca's product ceiling is lower — check with your iwoca contact for the current ceiling and validate against it on your front end.

   If the customer has an existing loan, amount represents the additional funds requested (response includes is_topup: true).

2. 2
   Check the status

   Poll GET /applications/latest/ or use webhooks (application_status_changed) to track progress. The is_closed field tells you whether the application can still be modified.

3. 3
   Update if needed

   Use PATCH /applications/latest/ to change amount, duration, or purpose. Only works while the application is still open (open, action_required, awaiting_underwriter, or in_underwriting).
