I am trying to access this endpoint, where signature parameter has to be sent as query parameter ^Postman

As you can see i passed my secret key as the value for signature key. It is not working. So what am i really missing here ? or do i need to do some transformations to the secret key ? please help me understand it and advance thanks!

It looks like you are putting the timestamp before the recvWindow in your query string.

timestamp is always the last parameter and the order of the parameters in the docs clearly puts recvWindow before timestamp.

I managed to get it working with query string recvWindow=60000&timestamp=1652512756366

Secret key and signature are two different things.

You need to sign the parameters with your secret key. This process produces a signature. And then you pass this resulting signature to the payload.

I'm not sure how to produce the signature in C , however Binance docs show an example of signing the data in console with openssl (scroll right on all 3 examples).
