Binance API - Working with Signatures
I'll keep it short. Should you be using the Binance API and trying to retrieve data that needs a signed message, then you most likely will get the "Signature for this request is not valid" error. I spent one day finding out what actually was the problem. No, it wasnt the recvWindow set to 5000. My timer was just 1 second off (1000ms). Here's the solution. You only have to sign the ARGUMENT LIST, not the base url itself.. Just leave "https://api.binance.com/api/v3/order?" out, sign the rest, put it all together and off you go.
