Subaccount transfer

How can I get subaccount transfers to and from certain subaccount, using only this subaccount API keys?

You can do that from 1) master account key OR 2) sub account key.

  1. For master account key, you can move funds from one sub acct to another sub account by:

POST /sapi/v1/sub-account/universalTransfer

  1. For a sub account key, you can move funds to another sub acct under the same master account by:

POST /sapi/v1/sub-account/transfer/subToSub
