Example usage of https://godoc.org/golang.org/x/oauth2/clientcredentials

http-client-example.go

package main

import (
	"fmt"
	"golang.org/x/net/context"
	cc "golang.org/x/oauth2/clientcredentials"
	"io/ioutil"
	"net/http"
	"os"
)

type SpecialClient struct {
	*http.Client
}

func main() {
	client := NewClient(
		os.Getenv("CLIENT_ID"),
		os.Getenv("CLIENT_SECRET"),
	)

	// the client will update its token if it's expired
	resp, err := client.Get("http://some.remote.resource/path/to/resource")

	if err != nil {
		panic(err)
	}

	body, _ := ioutil.ReadAll(resp.Body)
	defer resp.Body.Close()

	// If response code is 200 it was successful
	if resp.StatusCode == 200 {
		fmt.Println("The request was successful. Response below:")
		fmt.Println(string(body))
	} else {
		fmt.Println("Could not perform request to the endpoint. Response below:")
		fmt.Println(string(body))
	}
}

func NewClient(cid, csec string) *SpecialClient {

	// this should match whatever service has given you
	// client credential access
	config := &cc.Config{
		ClientID:     cid,
		ClientSecret: csec,
		TokenURL: "http://some.remote.resource/token",
		Scopes:   []string{"scope:name"},
	}

	// you can modify the client (for example ignoring bad certs or otherwise)
	// by modifying the context
	ctx := context.Background()
	client := config.Client(ctx)

	return &SpecialClient{client}
}

Was looking all over for this!

@dv-blk You're welcome :)

Very helpful snippet, thank you so much! :) I did notice a small typo in the print line for error handling "endpoind".
