# Introduction

With Elation API 2.0, you can create applications that interact with key components of the Elation platform.  We have a few design goals in mind:

### Comprehensive Read Access to the patient chart

An Elation patient chart is comprised of the patient's clinical profile and documents.  You will have read access to a patient's demographics, problem list, allergies, histories, vitals, immunizations, appointments, visits, bills, medications, and reports.

### Selective Write Access with coded patient chart data

You can add coded data to enrich the patient chart.  For example, you can create new patient charts, and create CVX-coded immunizations.  You can also create LOINC-coded lab results, SOAP visit notes, and NDC-coded medication in the patient chart.

### PMS-integration ready

Our Scheduling and Billing API enable seamless integration with 3rd-party PMS systems.  You can easily build single-directional synchronization for appointment and billing data using Webhooks.

### CCDA-based data exchange

You can export a patient chart in the CCDA format.
