Validating request body always returns error

[CodebyOmar]

I'm trying to use govalidator and it always returns error even if i send the correct data, may i'm doing it wrong because this is my first time using this package.

package notifier

import (
	"encoding/json"
	"net/http"

	"github.com/thedevsaddam/govalidator"
)

// Payload is request data structure expected
type Payload struct {
	TransactionReference    string              `json:"transactionReference"`
	Timestamp                    string               `json:"timestamp"`
	ItemID                           string               `json:"itemId"`
	AmountPaid                  govalidator.Int `json:"amountPaid"`
	Status                            string               `json:"status"`
}

type res struct {
	Message string `json:"message"`
	Data    *Payload
}

// UpdatePayment Receives payment details and sends to accounting API
func UpdatePayment(w http.ResponseWriter, r *http.Request) {
	p := new(Payload)

	opts := govalidator.Options{
		Request:         r,
		Data:            &p,
		Rules:           rules,
		RequiredDefault: true,
	}

	req := govalidator.New(opts)
	e := req.Validate()

	if len(e) > 0 {
		validationErr := map[string]interface{}{"data": e, "status": "error"}
		json.NewEncoder(w).Encode(validationErr)
		return
	}

	retMsg := &res{
		Message: "Payment notification recieved",
		Data:    p,
	}

	json.NewEncoder(w).Encode(retMsg)
}

second file valitadions.go

package notifier

import "github.com/thedevsaddam/govalidator"

var rules = govalidator.MapData{
	"amountPaid":                  []string{"required", "numeric"},
	"timestamp":                    []string{"required", "date"},
	"transactionReference":   []string{"required"},
	"itemId":                          []string{"required"},
	"status":                           []string{"required"},
}

forgot to mention i'm running this in a cloud function. Meaning the payload would be located in r.body

solved. changed p := new(Payload) to var p Payload.
