Getting started

Quick start guide for integrating with the FirstQuadrant API

The FirstQuadrant API provides programmatic access to all the features of the FirstQuadrant CRM platform. This guide will help you get started with making your first API call.

Base URL

All API requests should be made to:

https://api.us.firstquadrant.ai/v5

Authentication

Before making any API requests, you’ll need to authenticate. FirstQuadrant supports two authentication methods:

1. API Keys - Best for server-to-server integrations
2. Access Tokens - For user-specific actions

See the Authentication guide for detailed instructions on obtaining and using credentials.

Making your first request

Here’s a simple example to test your authentication and get your user profile:

cURL

curl https://api.us.firstquadrant.ai/v5/me \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "FirstQuadrant-Organization-ID: org_YOUR_ORG_ID"

Response format

All successful API responses return JSON data. The response will vary based on the endpoint, but typically follows these patterns:

Single resource

{
  "id": "con_abc123",
  "email": "[e-mail]",
  "firstName": "John",
  "lastName": "Doe",
  "createdAt": "2024-01-15T10:30:00Z",
  "updatedAt": "2024-01-15T10:30:00Z"
}

Resource collection
