Hong Kong-based bitcoin and cryptocurrency exchange Bitfinex. announced today it will be upgrading their APIs next week. The company reports that even though their platform, trading engine, and APIs have remained reliable and performant it was time for an upgrade.
Thus, in order to continue to be able to accommodate current demand and future scaling, the Bitfinex REST and WebSocket APIs will be upgraded on Thursday, August 31st.
In order to continue to be able to handle spikes in platform load, Bitinex says they need to make adjustments to how it returns historical snapshot messages when authenticating to the WebSocket APIs.
Currently `hos`, `hts`, `hfts`, `hfos`, `hfls`, `hfcs` snapshots are returned in the WebSocket feed after authenticating. These snapshots will no longer be returned via the WebSocket feed (both V1 and V2) after August 31st and equivalent REST endpoints are available as a replacement. All update messages will remain unchanged.
If an API application relies on these historical snapshots, these changes may affect a developer’s application. For the benefit of users, the changes (more details here) will work to ensure optimal API performance, with minimal latency going forward.
