v1.4.0

Changes

• Add Service API for End User lookup (GET /end-users/{end_user_id})
  • New method on DifyBaseClient (available on chat/chatflow/workflow/completion clients): EndUserResponse getEndUser(String endUserId)
  • New model: EndUserResponse (id, tenant_id, app_id, type, external_user_id, name, is_anonymous, session_id, created_at, updated_at)
  • Use case: when other APIs return created_by as an end-user ID, resolve external_user_id / session_id
• Add Service API for Human Input Form (companion to the Human Input events shipped in 1.3.0)
  • HumanInputFormResponse getHumanInputForm(String formToken) — GET /form/human_input/{form_token}, fetch a paused form definition
  • void submitHumanInputForm(String formToken, HumanInputFormSubmitRequest request) — POST /form/human_input/{form_token}, submit inputs + selected action + user to resume the workflow
  • Methods live on DifyBaseClient so both workflow and chatflow apps can call them
  • New models: HumanInputFormResponse, HumanInputFormSubmitRequest
• Add Service API for Workflow Resume Events stream (GET /workflow/{workflow_run_id}/events)
  • New method on DifyWorkflowClient: void streamWorkflowEvents(String workflowRunId, String user, Boolean includeStateSnapshot, Boolean continueOnPause, WorkflowStreamCallback callback)
  • After submitting a human-input form, use this endpoint to re-subscribe to the resumed workflow's events (SSE)
  • include_state_snapshot=true replays a status summary of already-executed nodes; continue_on_pause=true keeps the stream open across multiple pauses
• Introduce reusable GET-SSE helper (executeGetStreamRequest) for future streaming endpoints
