# GET /private/verify_block_trade

`GET /private/verify_block_trade`

Verifies and creates a block trade signature. This is the first step in the block trade workflow - the first party calls this method to generate a signature that must be shared with the second party.

**Note:** In the API, the `direction` field is always expressed from the maker's perspective. This means that when you accept a block trade as a taker, the direction shown in the API represents the opposite side of your trade. For example, if you are buying puts as a taker, the API will show the operation as a "sell put" (maker's perspective), and you will be verifying and accepting a "sell put" block trade.
