You make an http request to the backend, containing the ID. Wherever this might come from doesn't matter. If you don't know where the ID comes from, neither do we.

reactive-form.html

        class="btn btn-success"
        (click)="onGetById()">
        Get user by ID 
        </button>

reactive-form.component.ts

    const uID =  prompt('Enter the ID of the user you wish to know about')
    id = Number(uID);
    console.log(`here`);
    console.log(id);
    this.userService.getById(id)
  } ```
----------------------------------------------
service.ts
```  getById(id: number) {
        return this.http.post('http://localhost:3000/get/get/',id)
        .subscribe((res) => {
            console.log(res);
        })
    }

    this.userForm = this.fb.group({
      Name: [null, [Validators.required, Validators.maxLength(16)]],
      Username: [null, [Validators.required, Validators.maxLength(16)]],
      Email: [null, [Validators.required, Validators.email]],
      UserPassword: [null, [Validators.required, Validators.minLength(8)]],
      Gender: [null, Validators.required],
      Country: [null, Validators.required],
      // postalCode: [null,Validators.maxLength(5)],
      Languages: [null, [Validators.required]],
      Notes: [null]
    })
  } ```

(click)="onGetById()"

onGetById should not have any parameter: you don't do anything with the parameter, other than overwriting it with what the prompt returns.
