create batch

Create a batch processing job from a JSONL file. Requires the Scale plan or above and approval for your organization. Access is disabled by default, including for new Scale subscriptions. Contact support@sync.so to request access. Without approval, creation and dry runs return 403 batch_access_not_enabled. Approved organizations on other plans get 402 plan_feature_unavailable with requiredPlan. Send the file in multipart field input (or the accepted file alias); it must be 5 MB or smaller and contain 20-500 records by default. A batch is queued and holds one slot of your plan’s batch concurrency limit; more active batches than that returns 429 concurrency_limit_reached. Each line must contain request_id, endpoint exactly /v2/generate, and a generation payload. To send the records as a JSON array instead of a file, use “Create Batch from Rows”, the application/json form of the same endpoint. Errors name a refused record by its 1-based line, counting non-empty lines: dialogue edit refusals return it as lineNumber, other record errors only in message.
