All Marketing Cloud Engagement features implement REST API. REST API uses JSON request and response bodies and resource endpoints. REST calls are synchronous. There are limits that apply to your use of REST API. For more information, see API Limits and Guidelines.

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)
