# Getting Started with GO
✋ CAUTION
This third-party integration guide might not be up-to-date with Strapi v4. Contributions (opens new window) are most welcome.
This integration guide is following the Quick Start Guide. We assume that you have fully completed its "Hands-on" path, and therefore can consume the API by browsing this url (opens new window).
If you haven't gone through the Quick Start guide, the way you request a Strapi API with GO (opens new window) remains the same except that you will not fetch the same content.
# Create a Go file
Be sure to have Go installed (opens new window) on your computer.
touch strapi.go
Go has built-in packages to make HTTP Requests like GET, POST, PUT, and DELETE. We will use the "net/http" package along with other packages.
# GET Request your collection type
Execute a GET
request on the restaurant
collection type in order to fetch all your restaurants.
Be sure that you activated the find
permission for the restaurant
collection type.
Example GET request
response, error := http.Get("http://localhost:1337/api/restaurants")
Example response
[{
"id": 1,
"name": "Biscotte Restaurant",
"description": "Welcome to Biscotte restaurant! Restaurant Biscotte offers a cuisine based on fresh, quality products, often local, organic when possible, and always produced by passionate producers.",
"created_at": "2021-03-31T11:37:16.964Z",
"updated_at": "2021-03-31T11:37:16.975Z",
"categories": [{
"id": 1,
"name": "French Food",
"created_by": 1,
"updated_by": 1,
"created_at": "2021-03-31T11:36:23.164Z",

},
{

"updated_at": "2021-03-07T10:10:19.649Z"
}
]
}]
# Example
package main
import (
"fmt"
"io/ioutil"
"net/http"
)
func main() {
getD()
}
func getD() {
fmt.Println("Getting data...")
res, error := http.Get("http://localhost:1337/api/restaurants")
if error != nil {
fmt.Printf("The HTTP request failed with error %s\n", error)
} else {
data, _ := ioutil.ReadAll(res.Body)
fmt.Println(string(data))
}
}
# POST Request your collection type
Execute a POST
request on the restaurant
collection type in order to create a restaurant.
Be sure that you activated the create
permission for the restaurant
collection type and the find
permission for the category
Collection type.
Example POST request
postRest, _ := json.Marshal(map[string]string{
"name": "Nwanyi Igbo",
"description": "This is a very nice place to eat native soup",
})
responseBody := bytes.NewBuffer(postRest)
resp, error := http.Post("http://localhost:1337/api/restaurants", "application/json", responseBody)
Example response
{
"id": 2,
"name": "Nwanyi Igbo",
"description": "This is a very nice place to eat native soup",
"created_at": "2021-03-04T09:57:11.669Z",
"updated_at": "2021-04-04T09:57:11.669Z",
"categories": []
}
# Example
package main
import (
"bytes"
"encoding/json"
"fmt"
"io/ioutil"
"log"
"net/http"
)
func main() {
postD()
}
func getD() {
fmt.Println("Getting data...")
resp, error := http.Get("http://localhost:1337/api/restaurants")
if error != nil {
fmt.Printf("The HTTP request failed with error %s\n", error)
} else {
data, _ := ioutil.ReadAll(resp.Body)
fmt.Println(string(data))
}
}
func postD() {
fmt.Println("Posting data...")
//Encode the data
postRest, _ := json.Marshal(map[string]string{
"name": "Nwanyi Igbo",
"description": "This is a very nice place to eat native soup",
})
responseBody := bytes.NewBuffer(postRest)
resp, error := http.Post("http://localhost:1337/api/restaurants", "application/json", responseBody)
//Handle Error
if error != nil {
log.Fatalf("An Error Occured %v", error)
}
defer resp.Body.Close()
//Read the response body
body, error := ioutil.ReadAll(resp.Body)
if error != nil {
log.Fatalln(error)
}
fmt.Println(string(body))
}
# PUT Request your collection type
Execute a PUT
request on the restaurant
collection type in order to update the category of a restaurant.
Be sure that you activated the update
permission for the restaurant
collection type.
PUT Request is sligtly different as we need to target the particular thing we want update. We do this by first making a request to http://localhost:1337/api/restaurants/1 and then update what we want to update. In this example, we are going to update "Biscotte Restaurant" to "Restaurant Home".
Example PUT request
putRest, _ := json.Marshal(map[string]string {
"name": "Resturant Homes",
})
client := &http.Client{}
url := "http://localhost:1337/api/restaurants/1"
req, error := http.NewRequest(http.MethodPut, url, bytes.NewBuffer(putRest))
req.Header.Set("Content-Type", "application/json")
Example response
{
"id": 1,
"name": "Resturant Homes",
"description": "Welcome to Biscotte restaurant! Restaurant Biscotte offers a cuisine based on fresh, quality products, often local, organic when possible, and always produced by passionate producers.",
"published_at": "2021-03-07T10:10:46.949Z",
"created_at": "2021-03-07T10:08:53.929Z",
"updated_at": "2021-03-07T14:06:01.567Z",
"categories": [{
"id": 1,
"name": "French Food",
"published_at": "2021-03-07T10:09:43.232Z",
"created_at": "2021-03-07T10:09:34.135Z",
"updated_at": "2021-03-07T10:09:43.280Z"
},
{
"id": 2,
"name": "Brunch ",
"published_at": "2021-03-07T10:10:19.608Z",

# Conclusion
Here is how to request your collection types in Strapi using Go. When you create a collection type or a single type you will have a certain number of REST API endpoints available to interact with.
We just used the GET, POST and PUT methods here but you can get one entry, and delete an entry too. Learn more about API Endpoints.
