v22.0.0

[22.0.0] - revision 2026-04-15

Added

• Conversations API
  • Send an outbound message to a profile with Create Conversation Message. Supports SMS and WhatsApp — the channel is determined automatically from the conversation. Conversation message endpoints use the SMALL rate limit tier (3 requests/second burst, 60 requests/minute steady).
  • Retrieve the conversation thread for a given profile with Get Conversation for Profile, or include it inline on profile retrievals using ?include=conversation.

Changed

• Drag-and-drop templates
  • Create drag-and-drop email templates programmaatically by setting editor_type: SYSTEM_DRAGGABLE and providing a definition body (mutually exclusive with html) via Create Template. DnD template endpoints use the SMALL rate limit tier (3 requests/second burst, 60 requests/minute steady).
  • List and retrieve drag-and-drog templates with Get Templates and Get Template. Use additional-fields[template]=definition to include the full template definition in the response.
  • Update an existing drag-and-drop template’s definition, name, or text independently via Update Template.
