• Login with your username / email and password into the BTSE website
• Click on Account on the top right hand corner
• Select the API tab
• Click on New API button to create an API key and passphrase. (Note: the passphrase will only appear once)
• Use your API key and passphrase to construct a signature.

Subscribe to Orderbook incremental updates through the endpoint wss://ws.btse.com/ws/oss/spot. The format of topic will be update:symbol_grouping (eg. update:BTC-USD_0). The first response received will be a snapshot of the current orderbook (this is indicated in the type field) and 50 levels will be returned. Incremental updates will be sent in subsequent packets with type delta.

Bids and asks will be sent in price and size tuples. The size sent will be the new updated size for the price. If a value of 0 is sent, the price should be removed from the local copy of the orderbook.

To ensure that the updates are received in sequence, seqNum indicates the current sequence and prevSeqNum refers to the packet before. seqNum will always be one after the prevSeqNum. If the sequence is out of order, you will need to unsubscribe and re-subscribe to the topic again.

Also if crossed orderbook ever occurs when the best bid higher or equal to the best ask, please unsubscribe and re-subscribe to the topic again.
