# Add Calendar Event

`POST /v1/projects/{projectId}/insights/events`

Put a campaign on this brand’s calendar. Requires an API key with project:write. Returns the whole calendar back, so a client never has to guess how the change reordered it. There is deliberately no edit endpoint — Migma’s calendar supports adding, removing and marking done, and nothing else.

## Path parameters

- `projectId` string, required

## Request body

- AddCalendarEventRequest
  - `title` string, required
  - `suggestedDate` string, required — YYYY-MM-DD.

## Response `200`

      - `description` string, required — One line on what it should say and why now.
      - `prompt` string, required — A ready-to-send brief — pass it straight to POST /v1/projects/emails/generate.
      - `priority` 'high' | 'medium' | 'low', required
      - `category` string — Short label for display, e.g. "Seasonal", "Promotion".
