REST API

The REST API uses JSON request and response bodies and resource endpoints to support multi-channel use. All new Marketing Cloud technologies implement REST API. REST calls are synchronous, with timeout values of 120 for non-tracking operations and 300 seconds for tracking and data retrieve operations. The maximum payload of any call is four megabytes.

Use the REST API for this functionality:

• Contacts
• Content Builder
• Journey Builder
• Mobile Connect
• MobilePush
• Campaigns
• Triggered Sends (may also use SOAP)
