Check this before submitting a payment to avoid duplicate Xero entries. ## OpenAPI ````yaml GET /xero/payments openapi: 3.1.0 info: title: Breezing Public API version: 1.0.0 description: >- Crypto accounting API for programmatic access and AI agents. Authenticate with an API key using the Authorization header: `Bearer brz_...` servers: - url: https://api.breezing.io/v1 security: - BearerAuth: [] paths: /xero/payments: get: tags: - Xero summary: List payments already booked on Xero for a transaction description: >- List every payment and bank transaction previously booked in Xero for one Breezing transaction via the "Submit payment on Xero" flow (dashboard button or POST /xero/payments), newest first. Call this BEFORE POST /xero/payments: that endpoint is NOT idempotent, and re-submitting a transaction that already has entries here books duplicate entries in Xero. Reads Breezing's own booking records; no Xero API call is made, so this works even while the Xero connection is expired (entries deleted directly in Xero will still be listed). Returns 404 if the transaction does not exist. parameters: - schema: type: string description: >- Organization ID.
