how to fetch data from another api with body raw json

i have default body raw json and want to paste it into a struct so it can fetch data automatically and save it into a struct

Body Raw Json

 {
	"jsonrpc": "2.0",
	"params": {
	}
}

Response from api

{
"jsonrpc": "2.0",
"id": null,
"result": {
	"status": 200,
	"response": [
		{
			"service_id": 1129,
			"service_name": "Adobe Illustrator",
			"service_category_id": 28,
			"service_category_name": "License Software",
			"service_type_id": 25,
			"service_type_name": "Software",
			"create_date": "2020-03-09 03:47:44"
		},
],
	"message": "Done All User Returned"
}

}

I want to put it in the repository file so I can get data automatically

Repo file

// Get request
resp, err := http.Get("look at API Response Example")
if err != nil {
	fmt.Println("No response from request")
}

defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body) // response body is []byte
if err != nil {
	return err
}

// data that already fetch accomadate to struct  
var result models.OdooRequest
if err := json.Unmarshal(body, &result); err != nil {  
	fmt.Println("Can not unmarshal JSON")
}

for _, rec := range result.Response {
	fmt.Println(rec.ServiceName)
}
return err

after being fetched then accommodated into a struct

struct

type OdooRequest struct {
	Response []UpsertFromOdooServices
}

Sure, here's a rough way to make that request and read the response:

package main

import (
	"bytes"
	"encoding/json"
	"fmt"
	"net/http"
)

type OdooRequest struct {
	Result struct {
		Status   int `json:"status"`
		Response []struct {
			ServiceID           int    `json:"service_id"`
			ServiceName         string `json:"service_name"`
			ServiceCategoryID   int    `json:"service_category_id"`
			ServiceCategoryName string `json:"service_category_name"`
			ServiceTypeID       int    `json:"service_type_id"`
			ServiceTypeName     string `json:"service_type_name"`
			CreateDate          string `json:"create_date"`
		} `json:"response"`
		Message string `json:"message"`
	} `json:"result"`
}

func main() {
	if err := run(); err != nil {
		panic(err)
	}
}
func run() error {
	resp, err := http.Post(
		"ADD_URL_HERE",
		"application/json",
		bytes.NewBufferString(`{"jsonrpc": "2.0","params": {}}`),
	)
	if err != nil {
		return err
	}
	defer resp.Body.Close()
	var odooResp OdooRequest
	if err := json.NewDecoder(resp.Body).Decode(&odooResp); err != nil {
		return err
	}
	for _, rec := range odooResp.Result.Response {
		fmt.Println(rec.ServiceName)
	}
	return nil
}
