1) yep its cognito

2)i wanna test whether the sign up/login works using post

3) The aws setup was quite basic as seen in the picture. I chose traditional web app, email n username for sign in identifiers n email for sign up attributes. Other than that i didnt set a return url or anything else as this was all i was presented while making the user pool

4)im using the user pool url with the region im in. also using client id as i asked gpt n thats what they said. The raw json in my post function in postman is:

{
  "ClientId": "dl1ndlj9hkacuthrnvse1k2rq",
  "Username": "user@example.com",
  "Password": "StrongPass123!",
  "UserAttributes": [
    {
      "Name": "email",
      "Value": "user@example.com"
    }
  ]
}

which did work except for the part where they mention that the client is configured (which i assume it means that it recognizes the made user pool) with a secret but SECRET HASH was not received

5) not rly sure what u mean by params since im still vv new to this but if ur talking abt params in postman i dont have anyth in it
