How to Install Mautic and Integrate With SuiteCRM: Complete Developer Guide (2026)

8. Manual Plugin-Free Integration Overview

The manual integration approach involves:

1. – Authenticating via OAuth2 in both Mautic and SuiteCRM

2. – Mapping fields between systems

3. – Fetching and updating contacts using API calls

4. – Automating the sync with cron jobs

5. – Logging errors for monitoring

This ensures plugin-free synchronization while keeping full control.

9. Authentication & API Access

Mautic OAuth2 Authentication

1. Request Access Token

POST https://mautic.example.com/oauth/v2/token
Content-Type: application/x-www-form-urlencoded

client_id=YOUR_CLIENT_ID&
client_secret=YOUR_CLIENT_SECRET&
grant_type=client_credentials

2.  

3. Use Token for API Requests

GET https://mautic.example.com/api/contacts
Authorization: Bearer ACCESS_TOKEN

SuiteCRM OAuth2 Authentication

1. Request Access Token

POST https://suitecrm.example.com/Api/access_token
Content-Type: application/json

{
  "grant_type": "password",
  "client_id": "suitecrm_client_id",
  "client_secret": "suitecrm_client_secret",
  "username": "api_user",
  "password": "api_password"
}

2. Use Token for API Requests

GET https://suitecrm.example.com/Api/V8/module/Contacts
Authorization: Bearer ACCESS_TOKEN

10. Field Mapping and Contact Sync

Example Field Mapping JSON:

{
  "email": "email_address",
  "first_name": "first_name",
  "last_name": "last_name",
  "company": "account_name",
  "phone": "phone_work"
}

Sync Contacts Steps:

1. Fetch Contacts from Mautic

2. Check if Contact Exists in SuiteCRM (by email)

3. Create or Update Contact in SuiteCRM

4. Push Updates Back to Mautic

PHP Example:

$response = $client->request('POST', $suitecrm_api, [
    'headers' => ['Authorization' => "Bearer $token"],
    'json' => $contactData
]);

11. Automating Synchronization with Cron Jobs

Example cron job (every hour):

0 * * * * /usr/bin/php /var/www/html/integration/sync_mautic_suitecrm.php >> /var/log/mautic-suitecrm-sync.log 2>&1

• Handles automatic sync of contacts, leads, and campaign activity

• Ensures near real-time integration without plugins

12. Error Handling and Logging

• Log API responses to monitor success/failure

• Handle token expiration automatically (refresh tokens)

• Track duplicate records and conflicts using unique identifiers

• Example PHP logging:

if ($response->getStatusCode() != 200) {
    error_log("Sync failed: " . $response->getBody());
}

13. Best Practices

• Use HTTPS for all API calls

• Backup both Mautic and SuiteCRM databases

• Monitor rate limits to avoid API throttling

• Validate field types and lengths to prevent sync errors

• Maintain audit logs for tracking synchronization

14. Conclusion

Integrating Mautic and SuiteCRM without plugins empowers businesses to automate marketing and sales workflows fully. By using OAuth2 authentication and REST API calls, you maintain full control over data synchronization, field mapping, and workflow automation.

This developer-focused method ensures cost-free, scalable, and secure integration, giving you complete control over your CRM and marketing automation ecosystem.
