A credit is reversed at most once; a reversal item that fails is retried on its own job (`POST /organization/jobs/{jobId}/retry`). A reversal lowers the balance like any debit, so it can bring an account to its loss limits. Passed, failed or expired accounts are not debited (`ACCOUNT_CLOSED`). The credit job must have finished (or been cancelled). Send `preview: true` to see how many credits, and how much, would be reversed. Requires **manage** permission on traders. ```bash curl -X POST "https://api.hyperprop.com/platform/v1/organization/balance-adjustments/jobs/5d1c7a2e-3b4f-4c8d-9e0a-1b2c3d4e5f60/reverse" \ -H "X-API-Key: hp_live_your_key_here" \ -H "Content-Type: application/json" \ -d '{"reason": "Credited in error"}' ``` ## OpenAPI ````yaml https://api.hyperprop.com/platform/openapi.json post /v1/organization/balance-adjustments/jobs/{jobId}/reverse openapi: 3.0.0 info: title: Hyperprop Platform API version: 1.0.0 description: >- REST API for the Hyperprop Trading Platform — provision evaluation and funded trading accounts, manage traders and plans, react to account lifecycle events via signed webhooks, and reconcile billing.
