Signature error in Futures

[Fran Rodríguez Carrasco]

Hi!

I'm trying to test the binance Futures API but I always get:

{
"code": -1022,
"msg": "Signature for this request is not valid."
}

I have this restrictions for the API

I have the correct API key and Secret key on my postman environment, but I'm getting the error with all requests which the signature is required.

What I'm doing wrong?

Thanks in advance.

This may be caused due to incorrect API credentials. Please confirm that you are using the correct environment and the correct environment variables.
