Gmail

Gmail is Google’s cloud based email service that allows you to access your messages from any computer or device with just a web browser.

Supports authentication: OAuth 2.0

Set up the agent connector

Register your Scalekit environment with the Gmail connector so Scalekit handles the authentication flow and token lifecycle for you. The connection name you create will be used to identify and invoke the connection programmatically. Then complete the configuration in your application as follows:

Caution

Google applications using scopes that permit access to certain user data must complete a verification process.

1. Set up auth redirects

   • In Scalekit dashboard, go to Agent Auth → Create Connection. Find Gmail and click Create.

     Note

     By default, a connection using Scalekit’s credentials will be created. If you are testing, go directly to the Usage section. Before going to production, update your connection by following the steps below.

   • Click Use your own credentials and copy the redirect URI. It looks like https://<SCALEKIT_ENVIRONMENT_URL>/sso/v1/oauth/<CONNECTION_ID>/callback.

     

   • Navigate to Google Cloud Console → APIs & Services → Credentials. Click + Create Credentials, then OAuth client ID. Choose Web application as the application type.

     

   • Under Authorized redirect URIs, click + Add URI, paste the redirect URI, and click Create.

     

2. Enable Gmail API

   • In Google Cloud Console, go to APIs & Services → Library. Search for “Gmail API” and click Enable.

     

3. Get client credentials

   Google provides your Client ID and Client Secret after you create the OAuth client ID in step 1.

4. Add credentials in Scalekit

   • In Scalekit dashboard, go to Agent Auth → Connections and open the connection you created.

   • Enter your credentials:

     • Client ID (from above)
     • Client Secret (from above)
     • Permissions (scopes beginning with gmail — see Google API Scopes reference)

     

   • Click Save.

Usage

Connect a user’s Gmail account and make API calls on their behalf — Scalekit handles OAuth and token management automatically.

You can interact with Gmail in two ways — via direct proxy API calls or via Scalekit optimized tool calls. Scroll down to see the list of available Scalekit tools.

Proxy API Calls

Node.js

import { ScalekitClient } from '@scalekit-sdk/node';
import 'dotenv/config';

const connectionName = 'gmail'; // get your connection name from connection configurations
const identifier = 'user_123';  // your unique user identifier

// Get your credentials from app.scalekit.com → Developers → Settings → API Credentials
const scalekit = new ScalekitClient(
  process.env.SCALEKIT_ENV_URL,
  process.env.SCALEKIT_CLIENT_ID,
  process.env.SCALEKIT_CLIENT_SECRET
);
const actions = scalekit.actions;

// Authenticate the user
const { link } = await actions.getAuthorizationLink({
  connectionName,
  identifier,
});
console.log('🔗 Authorize Gmail:', link); // present this link to your user for authorization, or click it yourself for testing
process.stdout.write('Press Enter after authorizing...');
await new Promise(r => process.stdin.once('data', r));

// Make a request via Scalekit proxy
const result = await actions.request({
  connectionName,
  identifier,
  path: '/gmail/v1/users/me/profile',
  method: 'GET',
});
console.log(result);

Python

import scalekit.client, os
from dotenv import load_dotenv
load_dotenv()

connection_name = "gmail"    # get your connection name from connection configurations
identifier = "user_123"      # your unique user identifier

# Get your credentials from app.scalekit.com → Developers → Settings → API Credentials
scalekit_client = scalekit.client.ScalekitClient(
    client_id=os.getenv("SCALEKIT_CLIENT_ID"),
    client_secret=os.getenv("SCALEKIT_CLIENT_SECRET"),
    env_url=os.getenv("SCALEKIT_ENV_URL"),
)
actions = scalekit_client.actions

# Authenticate the user
link_response = actions.get_authorization_link(
    connection_name=connection_name,
    identifier=identifier
)
# present this link to your user for authorization, or click it yourself for testing
print("🔗 Authorize Gmail:", link_response.link)
input("Press Enter after authorizing...")

# Make a request via Scalekit proxy
result = actions.request(
    connection_name=connection_name,
    identifier=identifier,
    path="/gmail/v1/users/me/profile",
    method="GET"
)
print(result)
