REST API for Perfex CRM – Connect your Perfex CRM with third party applications

The REST API module for Perfex CRM is a comprehensive solution developed by Themesic that allows you to expose and consume your Perfex CRM data through a complete REST API interface. Designed for developers, integrators, and businesses that need to connect their CRM with external applications, this module removes communication barriers between systems and opens up a world of automation possibilities.

The module operates over HTTPS and uses JSON as the data format, following RESTful principles with standard HTTP methods such as GET and POST. This means that any application capable of making HTTP requests can interact with your Perfex CRM securely and in a structured way. The API documents more than 70 routes and 139 operations in an OpenAPI 3.0 specification, greatly facilitating the work of developers who need to integrate the CRM with other platforms.

Its standout features include endpoints for managing customers, contacts, invoices, payments, leads, support tickets, and more. The module also incorporates a webhook system with over 120 events in 22 groups, signed with HMAC to ensure the security of asynchronous deliveries with automatic retries. Additionally, it includes a batch operations endpoint that allows executing up to 50 operations in a single request, optimizing performance in mass synchronization scenarios.

Permission management is granular: you can create API tokens with specific permissions per resource (read, create, update, delete), allowing you to grant each integration only the access it needs. This is especially valuable in environments where multiple applications connect to the same CRM.

The module is compatible with automation tools like n8n, for which there is an official community node covering 19 resources with 108 operations. It also includes a native MCP server that exposes 148 permission-filtered tools, ideal for integrating artificial intelligence agents with CRM data.

If you manage a Perfex CRM and need to synchronize WooCommerce orders, capture leads from web forms, automate invoice follow-ups, or simply connect your CRM with any third-party application, this module provides the necessary infrastructure to do so robustly and scalably.
