# Transfer multiple Multi Tokens

`POST /v3/multitoken/transaction/batch`

## Request

- Base URL: `https://api.tatum.io`
- URL: `https://api.tatum.io/v3/multitoken/transaction/batch`
- Auth: API key in header `x-api-key`

/v3/multitoken/transaction/batch

**2 credits per API call**

Transfer Multi Token Batch from account to various other accounts in one transaction. Transfer multiple Multi Tokens token from smart contract defined in contractAddress.

Multiple token with specified tokenIds and values can be transferred. This method invokes ERC1155 method safeTransfer() to transfer the token in case of ETH, Celo and BSC.

This API is supported for the following blockchains:

*   BNB Smart Chain
*   Celo
*   Ethereum
*   Harmony
*   Klaytn
*   KuCoin Community Chain
*   Polygon
*   Flare
*   Cronos
*   Base
*   Avalanche
*   Fantom
*   Optimism

**Signing a transaction**

When transferring multiple Multi Tokens, you are charged a fee for the transaction, and you must sign the transaction with the private key of the blockchain address from which the fee will be deducted.

Providing the private key in the API is not a secure way of signing transactions, because the private key can be stolen or exposed. Your private keys should never leave your security perimeter. You should use the private keys only for testing a solution you are building on the **testnet** of a blockchain.

For signing transactions on the **mainnet**, we strongly recommend that you use the Tatum [Key Management System (KMS)](https://github.com/tatumio/tatum-kms) and provide the signature ID instead of the private key in the API. Alternatively, you can use the [Tatum JavaScript client](https://github.com/tatumio/tatum-js/tree/v2).

## Query parameters

- `testnetType` 'ethereum-sepolia' | 'flare-coston' | 'flare-coston2' | 'flare-songbird': Specifies the testnet type. The default is ethereum-sepolia for Ethereum (ETH) currency and flare-coston for Flare (FLR) currency. Valid testnet types depend on the specified currency.

## Response `200`

OK

- union
  - TransactionHash
    - `txId` string, required: The hash (ID) of the transaction
  - SignatureId
    - `signatureId` string, uuid, required: The internal Tatum ID of the prepared transaction for Key Management Sysytem (KMS) to sign<br/>This is different from the <code>signatureId</code> parameter that you provided in the request body. The <code>signatureId</code> parameter in the request body specifies the signature ID associated with the private key in KMS.

## Other responses
