# ExecuteMultiCall

> Atomically execute a batch of operations via Execute_MultiCall

Atomically execute a batch of operations through Canton's `Execute_MultiCall` DAR choice. Each sub-operation is individually gated against its own functional group — a disabled group will cause the whole batch to be rejected.

Invoked through the two-phase [transaction flow](/agentic-api/transaction-flow) with:

* `operation = TRANSACTION_OPERATION_EXECUTE_MULTICALL`
* `params.execute_multicall = ExecuteMultiCallParams { … }`

## Params

<ParamField path="operations" type="MultiCallOp[]" required>
  Ordered list of sub-operations to execute atomically.
</ParamField>

<ParamField path="amulet_cids" type="string[]">
  Canton Coin amulets to be consumed by the batch.
</ParamField>

<ParamField path="holding_cids" type="string[]">
  CIP-56 holding contract IDs to be consumed by the batch.
</ParamField>

```proto theme={null}
message ExecuteMultiCallParams {
  repeated MultiCallOp operations   = 1;
  repeated string      amulet_cids  = 2;
  repeated string      holding_cids = 3;
}
```

<Warning>
  All sub-operations succeed or the entire batch is rolled back. MultiCall is the right tool when two or more actions must be strictly atomic (e.g. split + transfer in the same commit).
</Warning>

<Tip>
  Call [`GetAmulets`](/agentic-api/core/get-amulets) and [`GetActiveContracts`](/agentic-api/core/get-active-contracts) to pre-select the `amulet_cids` and `holding_cids` the batch should consume.
</Tip>
