Hello,
Starting from 2023-08-01 we started receiving errors “level2, level3, and full channels now require authentication. Exchange WebSocket Authentication | Coinbase Cloud Failed to subscribe” using wss://ws-feed.pro.coinbase.com and subscribe (level2 channel).
Is it new changes that force authentication for level2?
Previously we didn’t have this problem and all worked perfectly.

Thank you for quick response.
Could you advise on signature generation. It’s not totally clear what it should contain.
Based on the documentation it builds from 4 parameters, but seems like they are for API signature, not for Websocket connection
Could you provide example of how signature should look like for subscribe
?
Thank you in advance

We don’t need to pass api-key or passphrase for signature generation, right?
Just timestamp + hardcoded string

// Request
{
"type": "subscribe",
"product_ids": [
"BTC-USD"
],
"channels": [
"full"
],
"signature": "...",
"key": "...",
"passphrase": "...",
"timestamp": "..."
}
You need to pass same data to websocket subscribe message that you send as headers with REST API. Difference is only in message that is used to generate signature - timestamp + hardcoded string.
Now all is clear, thank you
Hi. I’m running into this same problem. I used to connect through WS to get L2 data but now I’m getting authentication errors. The problem that I have is that I don’t have an old API key created with a passphrase. If I now go to my account and create a new API key, there is no notion of a passphrase (I’m guessing this is the way the new Advanced API is supposed to work).
Is there a way to create an old type API with a passphrase or to connect to the old ws endpoint to obtain the L2 or full channels using new-style API keys (no passphrase) ?
Thanks
You are supposed to use “Advanced” Trade WebSocket now:
Please correct me if I’m wrong, but the new Advanced API does not provide a “full” channel?
Sorry but I’m not sure I understand, does the new “Advanced” trade websocket have a full (or L3) feed? According to this Advanced API ws-channels it only has a “level2” feed in adition to “market_trades” and a few other channels.
Yes was to your question - yes, it does not provide full channel.
