Response example (refinancing — refinanced_credit_operations)

For a refinancing credit operation, the GET response includes operation_type_enumerator: settlement_refinancing and the array refinanced_credit_operations, which lists the prior operation(s) being settled by this new contract. The example below uses final_disbursement_amount: 0 (no cash payout to the borrower—the new operation is sized to settle the prior obligation); see the note on final_disbursement_amount in this section.

Homologation / sample data

refinanced_credit_operations

Each object describes a prior credit operation included in this refinancing: refinanced_credit_operation_key and refinanced_contract_number identify it; due_balance and due_balance_reference_date are the payoff context used when structuring the new contract; refinanced_credit_operation_status_enumerator is the status of that refinanced operation at the time of the inquiry (not necessarily the new operation’s status). original_deadline refers to the prior operation’s term where applicable.

business_due_date (installments)

In each object under installments[], pay attention to business_due_date: it is the installment due date on the business-day calendar (working / banking days). It may match due_date or differ when the natural calendar date falls on a non-business day—use both fields together when reconciling schedules and cut-offs.

operation_type_enumerator

When operation_type_enumerator is settlement_refinancing, the credit operation is a refinancing debt—that is, it is issued under the refinancing flow (settling prior credit operations). Use this field to distinguish refinancing debts from other operation types.

final_disbursement_amount

final_disbursement_amount is the effective disbursement of the new credit operation. When there is no net amount paid to the borrower (no cash payout from the new loan), the platform does not rely on a separately informed disbursement: it computes the due balance (payoff) of the refinanced loan(s), and that amount is used as the disbursed amount of the new loan—the new operation is sized to settle the prior obligation.

2. Renegotiation — Batch simulation

Overview

Before creating a proposal, you can simulate batch renegotiation values for operations. The simulation shows affected installments, discounts, and the total amount due across multiple operations.

When amortization_type is present_amount, send only installment_key on each installment in operations[].installments[] for simulation. Per-installment paid_amount and discount_amount are not used on batch_proposal_simulation—they are required on POST /renegotiation/batch_proposal (see §3).

Attention

Batch renegotiation can only include operations from the same issuer and the same integration key. There is a limit of 50 operations per batch renegotiation.

Request

ENDPOINT
/renegotiation/batch_proposal_simulation
METHOD
POST
Warning

The discount_amount and discount_percentage fields must not be sent together in the same payload (root level).

Note

At the root, discount_amount and discount_percentage are mutually exclusive global discount options for the simulation payload. Per-installment paid_amount and discount_amount are documented under POST /renegotiation/batch_proposal only.

3. Renegotiation — Batch proposal

Overview

After simulating values, you can create a batch renegotiation proposal for multiple operations. The proposal generates a single payment method (bank slip and/or Pix) covering all operations in the batch.

For amortization type present_amount, each installment listed under operations[].installments[] must include paid_amount (amount paid or allocated for that installment), discount_amount (discount in BRL applied to the installment), and installment_key.

Attention

Batch renegotiation can only include operations from the same issuer and the same integration key. There is a limit of 50 operations per batch renegotiation.

Request

ENDPOINT
/renegotiation/batch_proposal
METHOD
POST

Paid amount and discount amount (installments)

For POST /renegotiation/batch_proposal only: when amortization_type is present_amount, each object in operations[].installments[] must include these fields (in addition to installment_key):

FieldTypeDescriptionMax length
paid_amountfloatAmount paid or allocated on that installment (BRL). Required when amortization_type is present_amount.15,2
discount_amountfloatDiscount in BRL applied to that installment. Required when amortization_type is present_amount; use 0 if there is no discount. Optional per installment for other amortization types, when applicable.15,2
Warning

The discount_amount and discount_percentage fields must not be sent together in the same payload (root level).

Note

At the root of the body, discount_amount and discount_percentage are mutually exclusive options for a global discount on the present value. The paid_amount and discount_amount fields inside each object in operations[].installments[] define the per-installment composition when amortization_type is present_amount (they are required in this mode and do not conflict with the root-level rule).

4. Renegotiation — Delete batch proposal

Overview

DELETE /renegotiation/batch_proposal/{request_control_key} cancels or deletes a batch renegotiation proposal that is not finalized or is still in a cancellable state. The proposal is marked canceled/deleted and any associated payment methods (bank slip, Pix, etc.) are invalidated.

Pass the same request_control_key you used when creating the batch with POST /renegotiation/batch_proposal (optional field on the create payload). If your integration maps this route to another identifier, follow your contract; the path parameter name in the API is request_control_key.

final_disbursement_amount (financial)

You may send final_disbursement_amount as 0 when you are not specifying a cash disbursement to the borrower. In that case, the simulation derives the disbursed amount of the new loan from the due balance (payoff) of the refinanced operation(s)—the same rule as in debt inquiry for final_disbursement_amount: the new credit is sized from what is owed on the previous loan(s), not from a user-defined payout amount.

Attention

Send borrower, financial, and refinanced_credit_operations with operation_key for each operation to refinance. See Definitions (refinancing simulation).

interest_grace_periodintInterest grace period (months)
principal_grace_periodintPrincipal grace period (months)
number_of_installmentsintNumber of installments
fine_configurationobjectFine configuration object — Late interest and penalty

Refinanced credit operations object

FieldTypeDescription
operation_keystring (UUID)Credit operation key to settle with this refinancing

Fine configuration object

FieldTypeDescription
contract_fine_ratefloatLate penalty rate as a decimal
interest_baseenumInterest base — Interest calculation basis
monthly_ratefloatMonthly late interest rate as a decimal

6. Standard loan (normal flow) — POST /signed_debt

Standard issuance uses POST /signed_debt without refinanced_credit_operations. The financial object carries the disbursed principal via disbursed_amount (cash payout to the borrower). Field shapes for borrower, additional_data.contract (opt-in signatures), disbursement_bank_accounts, and other objects follow the same definitions as in §7. Creating a refinancing—omit refinanced_credit_operations and use disbursed_amount instead of sizing from refinanced operations.

9. Webhooks — batch renegotiation

These events notify your systems when a batch renegotiation proposal (created via POST /renegotiation/batch_proposal) reaches a relevant lifecycle state—for example after payment (status: paid) or when the proposal is rejected (status: rejected).

webhook_type: renegotiation.batch_proposal

Use this payload to reconcile batch_proposal_status, payment method, and amounts with your internal records for the request_control_key / batch_proposal_key you track from creation.

Attention

A batch renegotiation proposal may move to rejected when the payment window expires without settlement, or when an installment is paid outside the batch renegotiation (invalidating the proposal). Treat status accordingly and use key as batch_proposal_key.

Example payload (status: paid)

{
"key": "217bf9ba-65e0-4416-8f5e-ef423d72b23c",
"data": {
"paid_in": {
"ispb": "32402502",
"name": "QI SOCIEDADE DE CRÉDITO DIRETO S.A.",
"code_number": 329
},
"paid_method_type": "pix"
},
"status": "paid",
"webhook_type": "renegotiation.batch_proposal",
"event_datetime": "2025-09-30 13:42:58"
}

Example payload (status: rejected)

{
"key": "217bf9ba-65e0-4416-8f5e-ef423d72b23c",
"data": {},
"status": "rejected",
"webhook_type": "renegotiation.batch_proposal",
"event_datetime": "2025-09-30 13:42:58"
}
