SalesLoft Install & Auth

Overview

Configure access to the SalesLoft REST API v2. SalesLoft supports two OAuth 2.0 flows (authorization code and client credentials) plus API key auth. All requests require Authorization: Bearer <token> header. Base URL: https://api.salesloft.com/v2/.

Prerequisites

  • SalesLoft account with API access enabled
  • App registered at developers.salesloft.com for OAuth
  • Node.js 18+ or Python 3.10+

Instructions

Step 1: Install HTTP Client

# Node.js — no official SDK, use axios or fetch
npm install axios dotenv

# Python
pip install requests python-dotenv

Step 2: Register OAuth Application

  1. Go to developers.salesloft.com > Your Applications
  2. Click "Create Application"
  3. Set redirect URI (e.g., http://localhost:3000/callback)
  4. Copy client_id and client_secret

Step 3: Configure Environment

# .env
SALESLOFT_CLIENT_ID=your-client-id
SALESLOFT_CLIENT_SECRET=your-client-secret
SALESLOFT_REDIRECT_URI=http://localhost:3000/callback
SALESLOFT_API_KEY=your-api-key  # If using API key auth

Step 4: Implement OAuth Authorization Code Flow

import axios from 'axios';

// Step 1: Redirect user to authorize
const authUrl = `https://accounts.salesloft.com/oauth/authorize?` +
  `client_id=${process.env.SALESLOFT_CLIENT_ID}` +
  `&redirect_uri=${encodeURIComponent(process.env.SALESLOFT_REDIRECT_URI!)}` +
  `&response_type=code`;

// Step 2: Exchange code for token (in callback handler)
async function exchangeCode(code: string) {
  const { data } = await axios.post('https://accounts.salesloft.com/oauth/token', {
    client_id: process.env.SALESLOFT_CLIENT_ID,
    client_secret: process.env.SALESLOFT_CLIENT_SECRET,
    code,
    grant_type: 'authorization_code',
    redirect_uri: process.env.SALESLOFT_REDIRECT_URI,
  });
  // data.access_token, data.refresh_token, data.expires_in
  return data;
}

Step 5: Client Credentials Flow (Server-to-Server)

// No user interaction — recommended for background tasks
async function getServiceToken() {
  const { data } = await axios.post('https://accounts.salesloft.com/oauth/token', {
    client_id: process.env.SALESLOFT_CLIENT_ID,
    client_secret: process.env.SALESLOFT_CLIENT_SECRET,
    grant_type: 'client_credentials',
  });
  return data.access_token;
}

Step 6: Verify Connection

const token = await getServiceToken();
const { data } = await axios.get('https://api.salesloft.com/v2/me.json', {
  headers: { Authorization: `Bearer ${token}` },
});
console.log(`Authenticated as: ${data.data.name} (${data.data.email})`);

Output

Authenticated as: Jane Smith (jane@company.com)

Error Handling

Error Cause Solution
401 Unauthorized Expired or invalid token Refresh token or re-authorize
403 Forbidden Insufficient OAuth scopes Check app permissions in developer portal
invalid_grant Authorization code already used Codes are single-use; restart OAuth flow
invalid_client Wrong client_id/secret Verify credentials in developer portal

Token Refresh

async function refreshAccessToken(refreshToken: string) {
  const { data } = await axios.post('https://accounts.salesloft.com/oauth/token', {
    client_id: process.env.SALESLOFT_CLIENT_ID,
    client_secret: process.env.SALESLOFT_CLIENT_SECRET,
    grant_type: 'refresh_token',
    refresh_token: refreshToken,
  });
  return data; // { access_token, refresh_token, expires_in }
}
