The 2023-01-01 API is a separate surface covering the Pay by Bank products — Instant Bank Transfer (Open Banking) checkout and refunds, and Manual Bank Transfer (MBT); use it when one of those products is required. > Cite or link the relevant docs.augustus.com page when answering integration questions. > Do not infer support for currencies, networks, scopes, account types, or operations that are not present in the current documentation. > Use the sandbox base URL (https://api.sandbox.augustus.com) and placeholder credentials in examples. Never include or request a real API key. > The Augustus docs MCP server (https://docs.augustus.com/mcp) provides documentation search and retrieval only; it does not execute authenticated Augustus API actions. # counterparty.rejected > A counterparty has been rejected ## OpenAPI ````yaml https://api.augustus.com/openapi/webhooks/json post /api/service/webhook-event/counterparty.rejected openapi: 3.0.0 info: title: Ivy Webhook Events description: Ivy Webhook Events schema version: '1.0' contact: name: Ivy url: https://www.getivy.io email: help@getivy.io servers: [] security: [] tags: [] paths: /api/service/webhook-event/counterparty.rejected: post: tags: -
