REST API

All Marketing Cloud Engagement features implement REST API. REST API uses JSON request and response bodies and resource endpoints. REST calls are synchronous. For a list of REST API endpoints and properties, see REST API Reference.

You can use REST API to manage several important marketing activities.

Creating, reading, updating, and deleting contacts
Managing content in Content Builder
Interacting with Journey Builder
Configuring and sending messages with Mobile Connect and MobilePush
Managing campaigns
Creating Triggered Sends (also available in SOAP API)

There are limits that apply to your use of REST API. For more information, see API Limits and Guidelines.
