Action Required: NATS Service will be Deprecated on 01/01/2020

Aug 12, 2019

Our NATS service will be deprecated by the end of this year in favor of WebSockets beginning 01/01/2020.

Customers can continue to use the NATS service until 12/31/2019. We will continue to offer support for the NATS service until 12/31/2019.

Our WebSockets service is built from the ground up and will give customers more flexibly and better latency moving forward. We encourage users to switch to using the WebSockets service as soon as possible

Below are some examples of how to connect and use Polygon.io WebSockets:
