Create or update multiple accounting vendors

Deprecated
Allows for the creation or updating of multiple vendors in a single request. Maximum 100 vendors per request. **Deprecation notice:** This synchronous endpoint is deprecated for high-volume use. Use POST /vendors/bulk-async instead — it avoids request timeouts on large batches and provides progress tracking via the batch polling API. This endpoint remains fully supported for existing integrations.

Client-generated unique key (UUID/ULID recommended). JSON requests: the first 2xx response is cached for 24h and replayed on a same-key retry with a matching body; a different body returns 422. Non-JSON requests (e.g. file uploads): the key is single-use — any same-key retry returns 422 regardless of body. See [Idempotency](https://docs.ottimate.com/idempotency) for full details.
