Parameters

Field	Type	Description
queue_id	string	Queue ID returned by Meta Broadcast. Recommended tracking key.
tx_hash	string	Optional fallback if queue ID is not available.
chain	string	Chain UID field accepted by API. For meta tracking, backend tracks on VSL.

Response Fields

Field	Type	Description
response.type	string	Tracker response type (meta_txn).
response.tx_status	string	Current status (pending, queued, success, failed).
response.is_completed	boolean	Whether the meta transaction reached a terminal state.
response.meta_txn_sub_type	string[]	Meta call types included (for example swap, transfer_voucher, withdraw_voucher).
response.meta_call_txn_response	object[]	Metadata summary originally passed in meta transaction payload.
response.status	object[]	Per-stage status details.

note

Use queue_id as the primary tracker key. It is created in broadcast and persisted by the API for status updates.
