Create Transfer (beta)

POST /v1/transfers/create

Create transfer to withdraw from wallet.

HTTP Request

POST /v1/transfers/create


A successful response returns an unconfirmed Transfer object with source_amount, dest_amount (the total the recipient will get), and total_fees (estimated maximum blockchain network fees charged by the blockchain for performing the transfer).



  • dest_currency string Required

    Token currency to send to the destination from the specified wallet. We will first check to make sure the wallet contains the amount you intend to send. However, since these are actual wallets, there could be a delay from the blockchain network that claims the balance is higher if multiple requests are being sent in a short window. This could result in the system thinking that it has enough balance but when the user confirms it, it will fail due to insufficient balance. Same issues can apply if a deposit is made to the wallet recently and not reflected in the blockchain yet. Possible values: BTC, ETH, SOL, AVAX, MATIC, DOT, XLM (more coming soon).

    • Wallet type ETH is compatible with the following currencies: ETH, MATIC, AVAX.
    • Wallet type SOL is compatible with the following currencies: SOL.
    • Wallet type BTC is compatible with the following currencies: BTC.
    • Wallet type DOT is compatible with the following currencies: DOT.
    • Wallet type XLM is compatible with the following currencies: XLM.
  • source string Required

    Unique wallet ID of the wallet to retrieve balance for.

  • dest string Required

    Any wallet address of the same wallet type as the source. For example, wallet_type of ETH will only be compatible with a dest that is an ethereum address.

    Blockchain specific transfer behaviors:

    • XLM (Stellar)

    Different from other protocol/chains, when transferring from Streambird wallet to an external address, user is required to include a memo attached to the end of the address separated by :. For example: GDQP2KPQGKIHYJGXNUIYOMHARUARCA7DJT5FO2FFOOKY3B2WSQHG4W37:3652667947 where the destination address is GDQP2KPQGKIHYJGXNUIYOMHARUARCA7DJT5FO2FFOOKY3B2WSQHG4W37 and stellar memo is 3652667947.

  • source_amount string Required

    decimal in string The total amount to transfer to the destination. If amount_includes_fees is set to true, we will auto calculate the fees to ensure the maximum amount withdrawn from the source is same as the specified amount. However, if amount_includes_fees is set to false, we will calculate the fees and auto increment the source_amount that gets returned in the response. We recommend that you show both the returned source_amount, dest_amount (how much recipient will receive), and also the total_fees to your user. Source amount stored with a transfer object will always be an all inclusive amount containing any fees calculated by the platform.

  • notes string

    Optional notes you want to store with this transaction.

  • Determines of the source_amount includes fees. If set to false, we will increment the source_amount automatically.

  • user_id string

    Optional user ID to send in with the transfer, which will trigger a platform validation to ensure the source wallet is owned by the specified user to avoid usage error.
