feat(workflows): implement Workflows & Meeting Reminder Automation Engine - #66
Conversation
…tomation Engine Add Prisma models for Workflow, WorkflowStep, WorkflowsOnEventTypes, WorkflowReminder. Implement WorkflowService in @calcom/features/workflows with timing calculation and reminder dispatch. Add viewerWorkflowsRouter in tRPC. Add Workflows dashboard UI at /workflows with template presets, trigger/action builders, and event type mapping.

Code Review
This pull request introduces a comprehensive workflows and automations feature, allowing users to configure personalized email, SMS, and WhatsApp reminders or follow-ups for meetings. It includes a new workflows management UI, tRPC router endpoints, a backend WorkflowService with scheduling logic, database schema updates, and unit tests. Key feedback highlights critical security vulnerabilities (IDOR) where team membership must be verified before performing workflow operations. Additionally, recommendations were made to wrap sequential database updates in a transaction for atomicity, parallelize reminder creation to avoid N+1 database writes, and align tRPC schema validations with the UI constraints.

There is a critical security vulnerability (Broken Object Level Authorization / IDOR) where any authenticated user can access, modify, or delete workflows belonging to any team simply by passing the target teamId. To prevent unauthorized access, we must verify that the requesting user is an accepted member of the specified team before performing any workflow operations.

The updateWorkflow method performs multiple sequential database operations (deleteMany for steps, deleteMany for activeOn, and update for the workflow itself) outside of a database transaction. If the final update operation fails, the existing steps and activeOn associations will have already been deleted, leaving the workflow in a corrupted and inconsistent state. Wrap these operations in a Prisma transaction to ensure atomicity.

if (input.steps) {

Add a required sendTo field for custom-recipient actions.
When EMAIL_ADDRESS, SMS_NUMBER, or WHATSAPP_NUMBER is selected, the form cannot set values.sendTo, so the workflow persists sendTo: null. The selected custom action therefore has no recipient. Register and require sendTo for these actions.

Enforce accepted team membership in WorkflowService. authedProcedure only authenticates the caller and forwards the client-supplied teamId. The service uses that ID without checking MembershipService.checkMembership, so a caller can target another known team across list, read, update, delete, and duplicate, and can create a workflow for that team. Call the shared membership check before team-scoped queries or creation. Reject when isMember is false.

Translate typed workflow errors through the existing tRPC boundary.
viewerWorkflowsRouter calls WorkflowService through authedProcedure, but errorConversionMiddleware converts only ErrorWithCode. These plain Error instances therefore become INTERNAL_SERVER_ERROR responses, and tRPC can expose their messages. Use typed service errors that the existing middleware maps to NOT_FOUND for the combined missing/access-denied case and BAD_REQUEST for validation. Keep WorkflowService independent of TRPCError.

Validate activeOn event-type ownership before creating mappings
The authenticated workflow procedures pass activeOn to WorkflowService, which writes each ID without checking its EventType.userId or EventType.teamId. scheduleRemindersForBooking then selects active workflows by eventTypeId alone and creates their reminders. A caller can therefore attach a workflow to a foreign event type and trigger its notifications for that event's bookings. Validate every event type against the workflow's user or team scope before creating mappings.

Non-atomic replacement can leave a workflow with no steps.
deleteMany for workflowStep and workflowsOnEventTypes commits before workflow.update at line 191. If the update rejects, the deletes stay committed. An invalid eventTypeId in input.activeOn violates the foreign key on WorkflowsOnEventTypes, so a single bad request permanently destroys every step of an existing workflow. The workflow then remains active: true with zero steps.
Wrap the delete and update in this.prisma.$transaction.

Add the missing Prisma migration before deployment.
20260319000000_drop_workflow_tables drops the workflow tables and enum types. The current schema.prisma defines them again, but no later migration recreates them. Generate and commit a migration with yarn prisma migrate dev so yarn prisma migrate deploy restores the required schema.

Validate offsets on every workflow mutation.
Both ZCreateWorkflowSchema and ZUpdateWorkflowSchema accept negative, zero, and omitted offsets. WorkflowService.calculateScheduledDate then reverses negative offsets and uses an event boundary when either value is omitted. Add .positive() to both schemas and validate time plus timeUnit whenever the effective trigger is BEFORE_EVENT or AFTER_EVENT. For partial updates, validate the merged existing and incoming values before WorkflowService.updateWorkflow persists them.

Note
Medium Risk
Adds a database migration and user-configurable email/SMS/WhatsApp automation paths; immediate send risk is limited because booking-time scheduling is not integrated in this PR.
Overview
This PR introduces meeting notification workflows end-to-end: new Prisma models (
Workflow,WorkflowStep,WorkflowsOnEventTypes,WorkflowReminder) and relations on users, teams, event types, and bookings, plus aWorkflowServicefor CRUD, duplication, trigger offset math, and creatingWorkflowReminderrows per booking step.Authenticated
viewer.workflowstRPC procedures (list,get,create,update,delete,duplicate) expose that service. The web app adds/workflows(login-gated), a main nav entry, and a listing UI with quick-start templates, create/edit dialog (triggers, email/SMS/WhatsApp actions, templates, event-type scoping), and list actions.WorkflowService.scheduleRemindersForBookingis implemented and unit-tested but not wired into booking create/reschedule/cancel in this diff, so configured workflows may not run until a follow-up hooks them up. The UI copy that empty event-type selection applies to “all event types” may not match scheduling, which only loads workflows linked viaactiveOn.Reviewed by Cursor Bugbot for commit d58ce4c.
