Create an installment plan

When you send this API request, our system will create an installment-plan that replaces any scheduled
payments you may have on the loans involved in this installment-plan. Once fully processed, the
installment-plan reaches the SCHEDULED status with its payment intents in PROPOSED status, ready to
be executed.

Key Parameters:
As the loan request is a complex operation, it has many parameters. The most important ones are:

• payment method (SCT or Direct debit)
• amount (in cents)
• debited account information in case of direct debit
• installments
• loans and their amounts
• installment date
• payment reference

Behavior

The endpoint returns 201 immediately with the installment-plan in DRAFT status. Cancelation of the
previous scheduled plans on the same loans, creation of payment intents, and activation of the new
plan happen asynchronously in a background task — poll the resource to observe the transition to
SCHEDULED. Retrying with the same salt_id returns the existing plan (dedup); when salt_id is
omitted, it is derived from the sorted loan_ids.
