	})

	params.SetCustomCode("867530")
	params.SetTo(t_int.Phone)
	params.SetChannel("sms")

	resp, err := client.VerifyV2.CreateVerification(verificationSid, params)
	if err != nil {
		fmt.Println(err.Error())

		return c.Status(http.StatusBadRequest).JSON(fiber.Map{
			"status": resp.Status,
			"err":    err.Error(),
		})
	} else {
		return c.Status(http.StatusOK).JSON(fiber.Map{
			"status": resp.Status,
		})
	}
