Server-to-server authentication

GitHub Actions

For workflows in an organization-owned repository, grant the built-in token permission to make Copilot requests:

permissions:
  contents: read
  copilot-requests: write

jobs:
  copilot:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v6
      - run: your-application
        env:
          GITHUB_TOKEN: $

The organization's Allow use of Copilot CLI billed to the organization policy must be enabled. This approach needs no GitHub App or stored authentication secret. For details, see GITHUB_TOKEN을 사용한 GitHub Actions에서 Copilot CLI 사용하기.

Other services and CI systems

For services outside GitHub Actions:

Create a GitHub App with the Copilot Requests repository permission set to Read & write.
Install it on the organization that should be billed. The current Copilot permission check requires All repositories access.

GitHub 앱에 대한 설치 액세스 토큰 생성 with a repository ID and the Copilot permission:

{
  "repository_ids": [123456789],
  "permissions": {
    "copilot_requests": "write"
  }
}

Pass the resulting ghs_ token to the runtime as COPILOT_GITHUB_TOKEN.

The organization must be enabled for Copilot requests from GitHub App installations. Installation tokens expire after one hour.

경고

Do not pass an installation token through the SDK's gitHubToken, github_token, or equivalent option. That option is for user tokens. Installation tokens must use the runtime environment authentication path.

Configure the runtime

The following examples assume the minted token is in INSTALLATION_TOKEN. They pass it only to the child runtime and disable fallback to stored user credentials.

TypeScript

import { CopilotClient, RuntimeConnection } from "@github/copilot-sdk";

const token = process.env.INSTALLATION_TOKEN;
if (!token) throw new Error("INSTALLATION_TOKEN is required");

const client = new CopilotClient({
    connection: RuntimeConnection.forStdio(),
    env: {
        ...process.env,
        COPILOT_GITHUB_TOKEN: token,
    },
    useLoggedInUser: false,
});

Python

import os

from copilot import CopilotClient, RuntimeConnection

client = CopilotClient(
    connection=RuntimeConnection.for_stdio(),
    env={**os.environ, "COPILOT_GITHUB_TOKEN": os.environ["INSTALLATION_TOKEN"]},
    use_logged_in_user=False,
)

package main

import (
	"log"
	"os"

	copilot "github.com/github/copilot-sdk/go"
)

func main() {
	token, ok := os.LookupEnv("INSTALLATION_TOKEN")
	if !ok {
		log.Fatal("INSTALLATION_TOKEN is required")
	}
	client := copilot.NewClient(&copilot.ClientOptions{
		Connection:      copilot.StdioConnection{},
		Env:             append(os.Environ(), "COPILOT_GITHUB_TOKEN="+token),
		UseLoggedInUser: copilot.Bool(false),
	})
	_ = client
}

Rust

use github_copilot_sdk::{ClientOptions, Transport};

fn main() {
    let token = std::env::var("INSTALLATION_TOKEN").expect("INSTALLATION_TOKEN is required");
    let options = ClientOptions::new()
        .with_transport(Transport::Stdio)
        .with_env([("COPILOT_GITHUB_TOKEN", token)])
        .with_use_logged_in_user(false);
    drop(options);
}

.NET

using System.Collections;
using GitHub.Copilot;

var token = Environment.GetEnvironmentVariable("INSTALLATION_TOKEN")
    ?? throw new InvalidOperationException("INSTALLATION_TOKEN is required");
var environment = Environment.GetEnvironmentVariables()
    .Cast<DictionaryEntry>()
    .ToDictionary(entry => (string)entry.Key, entry => entry.Value?.ToString() ?? "");
environment["COPILOT_GITHUB_TOKEN"] = token;

await using var client = new CopilotClient(new CopilotClientOptions
{
    Connection = RuntimeConnection.ForStdio(),
    Environment = environment,
    UseLoggedInUser = false,
});

Java

import com.github.copilot.CopilotClient;
import com.github.copilot.rpc.CopilotClientOptions;
import java.util.HashMap;
import java.util.Objects;

var environment = new HashMap<>(System.getenv());
var token = Objects.requireNonNull(
    System.getenv("INSTALLATION_TOKEN"), "INSTALLATION_TOKEN is required");
environment.put("COPILOT_GITHUB_TOKEN", token);

try (var client = new CopilotClient(new CopilotClientOptions()
        .setEnvironment(environment)
        .setUseLoggedInUser(false))) {
    // Use the client.
}

For in-process FFI, set COPILOT_GITHUB_TOKEN in the host environment before loading the runtime; per-client environment options are not supported. For an existing runtime URI, set it on that runtime process.

Symptom	Check
`401 Unauthorized`	Confirm the organization supports GitHub App installation authentication for Copilot.
`403 Resource not accessible by integration` or an error mentioning user information	Confirm the installation token is in `COPILOT_GITHUB_TOKEN`, not the SDK's explicit token option.
`403 Forbidden` from the Copilot API	Confirm the token request contains `repository_ids` and `copilot_requests: write`.
`403 Forbidden` with the required token request	Confirm the app installation has All repositories access, then mint a new token.
Requested model is unavailable	Confirm the organization's Copilot policy allows the model and the bundled runtime supports it.
Wrong account billed	Confirm the installation belongs to the intended organization.
