Hey, I am using Postman to test different APIs that require HMAC signing for authentication. I have successfully written code that goes in "Pre-request script" in Postman for one API (HMAC SHA256), but since every API is different I need a developer to update code for each API to authenticate and sign the request correctly. Each API has full documentation for signing/authenticating. APIs required: - Bittrex API: [login to view URL] - Bitfinex API: [login to view URL] - Kraken API: [login to view URL] - KuCoin API: [login to view URL] - Poloniex API: [login to view URL] We can add more APIs later but start with these 5. We will work in 'Team' in Postman so that we can easily collaborate.
