}Process multiple transfers in a single request. Transfers are executed sequentially — use this instead of sending many parallel single-transfer requests.
Each transfer in the array supports the same parameters as the single transfer endpoint. Results are returned per-transfer: failures in one transfer do not affect the others.
Why batch? Sending 50+ parallel requests to /accounts/transfer causes Firestore transaction contention on the source wallet, resulting in INTERNAL_ERROR failures. The batch endpoint eliminates this by processing transfers one at a time within a single HTTP call.
Limits: Maximum 200 transfers per batch.
Idempotency and evidence: Every transfer requires its own idempotencyKey. Live batch items also require the same commercial-evidence metadata as the single-transfer endpoint.
