Single-account reverts appear as batches of one; bulk reverts as one batch covering all their accounts. Use this to build an admin history view ("who reverted what, when, and why") and as the entry point for undo: pick a batch, inspect it with `GET /revert-batches/{batchId}`, and reverse it with `POST /revert-batches/{batchId}/undo`. `undoneCount` vs `accountCount` tells you the batch state at a glance: `0` = fully in effect, equal = fully undone, in between = partially undone (some accounts had new activity when the undo ran). **Example:** ```bash curl "https://api.hyperprop.com/platform/v1/organization/revert-batches?limit=20" \ -H "X-API-Key: hp_live_your_key_here" ``` ## OpenAPI ````yaml /api-reference/openapi.json get /v1/organization/revert-batches 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.
