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)
