Complete an adjustment remainder

post

https://api.wingspan.app/v3/payments/deductions/{deductionId}/complete

Complete all or part of a deduction remainder using Refund, OffPlatform or Close. Requires elevated authentication and Idempotency-Key. Refund requires payments.payable-payment:write and a paid, deposited source payable; card and off-platform payments are excluded. After 412, re-read the deduction and retry with its current ETag and a new Idempotency-Key.

Requires a session with recent MFA step-up for HighRiskWriteAction. If step-up is missing or expired, this operation returns 403 StepUpMfaRequired; create and verify an MFA challenge at /v3/platform/mfa-challenges with requiredFor: "HighRiskWriteAction", then retry.

Body Params

Dispose of all or part of an unused adjustment remainder. Requires elevated authentication and Idempotency-Key. Refund requires a paid source and cannot exceed the available refundable balance. After 412, re-read the resource and retry with a fresh Idempotency-Key and current If-Match.

remainderDisposition

string

enum

required

Allowed:

amount

double

A monetary amount as a JSON number in major units, with decimal places carrying the minor units defined for its currency (USD/EUR: 2, JPY: 0, BHD: 3, ...) — e.g. 100.00. Never a string and never minor-unit (cent) integers. The currency comes from the enclosing resource's currency field; amounts with more decimal places than the currency supports are rejected with 422 ValidationError. Wingspan converts to exact minor units at the service boundary, so callers never need sub-minor-unit precision.

Headers

Idempotency-Key

string

required

length between 1 and 255

^[\x21-\x7e]{1,255}$

Required idempotency key for this completion action.

If-Match

string

Optimistic-concurrency precondition. On PATCH and lifecycle action POSTs against resources with mutable lifecycle (Invoice, Payable, PayrollRun, Credit, Deduction), supply the ETag returned on the most recent read. Mismatch yields 412 Precondition Failed. If-Match: * accepts any current ETag.

X-Wingspan-Account

string

^(?:[A-Za-z0-9_.]{22}|[a-f0-9]{24})$

Select the Account for an Account-scoped operation. A direct ServiceAccount API key MUST supply this header, and the target must be within the ServiceAccount owner's or Authorization grant's Account boundary. A Person bearer may select an Account on which it has an active Stakeholder, and an Account session may select its bound Account (or a descendant only when the session explicitly includes descendants).
