Introduction
Understand how REST API structures CRM data access and enables consistent integrations across applications. Perfex CRM REST API provides predictable endpoints for retrieving and managing data.
Overview
REST API organizes data into resources such as clients, invoices, and projects. Each resource is accessed through a specific endpoint. Using tools like Data Builder for Perfex CRM, these endpoints can be generated without manual backend development.

REST API Structure
REST API follows a standard format:
- GET → retrieve data
- POST → create data
- PUT/PATCH → update data
- DELETE → remove data
Each endpoint represents a resource:
/clients/invoices
Example Use Case
A mobile app can request:
GET /clients
→ Returns list of clients in JSON format
With Data Builder, datasets can be customized before exposing via endpoints.
