Miro Core Workflow A — Boards & Items CRUD

Overview

The primary workflow for Miro integrations: full CRUD on boards and board items (sticky notes, shapes, cards, frames, tags) using the REST API v2 at https://api.miro.com/v2/.

Prerequisites

• Valid access token with boards:read and boards:write scopes
• Understanding of Miro item types (see miro-hello-world)

Board Operations

Create a Board

// POST https://api.miro.com/v2/boards
const board = await miroFetch('/v2/boards', 'POST', {
  name: 'Sprint Retro — Week 12',
  description: 'Team retrospective board',
  teamId: 'your-team-id',  // optional — creates in specific team
  policy: {
    sharingPolicy: {
      access: 'private',
      inviteToAccountAndBoardLinkAccess: 'no_access',
      organizationAccess: 'private',
    },
    permissionsPolicy: {
      collaborationToolsStartAccess: 'all_editors',
      copyAccess: 'anyone',
      sharingAccess: 'team_members_and_collaborators',
    },
  },
});

Get a Board

// GET https://api.miro.com/v2/boards/{board_id}
const board = await miroFetch(`/v2/boards/${boardId}`);
// Returns: id, name, description, owner, policy, createdAt, modifiedAt

List All Boards

// GET https://api.miro.com/v2/boards
// Supports filtering by team_id, project_id, query, sort, owner
const boards = await miroFetch('/v2/boards?limit=50&sort=last_modified');
for (const board of boards.data) {
  console.log(`${board.id}: ${board.name} (modified: ${board.modifiedAt})`);
}

Update a Board

// PATCH https://api.miro.com/v2/boards/{board_id}
await miroFetch(`/v2/boards/${boardId}`, 'PATCH', {
  name: 'Sprint Retro — Week 12 (CLOSED)',
  description: 'Archived — action items in Jira',
});

Delete a Board

// DELETE https://api.miro.com/v2/boards/{board_id}
await miroFetch(`/v2/boards/${boardId}`, 'DELETE');

Item CRUD Operations

Create Items

// Sticky Note — POST /v2/boards/{board_id}/sticky_notes
const note = await miroFetch(`/v2/boards/${boardId}/sticky_notes`, 'POST', {
  data: { content: 'Went well: team communication', shape: 'square' },
  style: { fillColor: 'light_green', textAlign: 'center' },
  position: { x: -200, y: 0 },
  geometry: { width: 199 },
});

// Shape — POST /v2/boards/{board_id}/shapes
const shape = await miroFetch(`/v2/boards/${boardId}/shapes`, 'POST', {
  data: { content: 'Decision Point', shape: 'rhombus' },
  style: { fillColor: '#ff6b6b', borderColor: '#333333', borderWidth: 2 },
  position: { x: 0, y: 200 },
  geometry: { width: 200, height: 200 },
});

// Card — POST /v2/boards/{board_id}/cards
const card = await miroFetch(`/v2/boards/${boardId}/cards`, 'POST', {
  data: {
    title: 'Improve deploy pipeline',
    description: 'Reduce deploy time from 15min to 5min',
    dueDate: '2025-04-01T00:00:00Z',
    assigneeId: 'user-id-123',
  },
  style: { cardTheme: '#2d9bf0' },
  position: { x: 200, y: 0 },
});

// Frame — POST /v2/boards/{board_id}/frames
const frame = await miroFetch(`/v2/boards/${boardId}/frames`, 'POST', {
  data: {
    title: 'What went well',
    format: 'custom',   // 'custom' | 'a4' | 'letter' | etc.
    type: 'freeform',   // 'freeform' | 'heap_map' | etc.
    showContent: true,
  },
  position: { x: -400, y: -200 },
  geometry: { width: 600, height: 400 },
});

// Text — POST /v2/boards/{board_id}/texts
const text = await miroFetch(`/v2/boards/${boardId}/texts`, 'POST', {
  data: { content: '<strong>Action Items</strong>' },
  style: { fontSize: 24, textAlign: 'left' },
  position: { x: 0, y: -300 },
  geometry: { width: 300 },
});

Get a Specific Item

// GET https://api.miro.com/v2/boards/{board_id}/items/{item_id}
const item = await miroFetch(`/v2/boards/${boardId}/items/${itemId}`);
// Or type-specific:
// GET /v2/boards/{board_id}/sticky_notes/{item_id}

Update an Item

// PATCH https://api.miro.com/v2/boards/{board_id}/sticky_notes/{item_id}
await miroFetch(`/v2/boards/${boardId}/sticky_notes/${noteId}`, 'PATCH', {
  data: { content: 'Updated: team communication was excellent' },
  style: { fillColor: 'light_blue' },
});

Delete an Item

// DELETE https://api.miro.com/v2/boards/{board_id}/items/{item_id}
await miroFetch(`/v2/boards/${boardId}/items/${itemId}`, 'DELETE');

Tags

Tags can be attached to sticky notes and cards (up to 8 per item).

// Step 1: Create a tag — POST /v2/boards/{board_id}/tags
const tag = await miroFetch(`/v2/boards/${boardId}/tags`, 'POST', {
  title: 'Action Item',
  fillColor: 'red',  // red | light_green | cyan | yellow | magenta | green | blue | etc.
});

// Step 2: Attach tag to an item — POST /v2/boards/{board_id}/items/{item_id}/tags
await miroFetch(`/v2/boards/${boardId}/items/${noteId}/tags`, 'POST', {
  tagId: tag.id,
});

// NOTE: Tag changes via API do NOT appear on the board in realtime.
// Users must refresh the board to see tag updates made via REST API.

Board Members

// List members — GET /v2/boards/{board_id}/members
const members = await miroFetch(`/v2/boards/${boardId}/members?limit=50`);

// Share board with a user — POST /v2/boards/{board_id}/members
await miroFetch(`/v2/boards/${boardId}/members`, 'POST', {
  emails: ['colleague@company.com'],
  role: 'commenter',  // 'viewer' | 'commenter' | 'editor' | 'coowner'
  message: 'Check out our retro board!',
});

Helper: Fetch Wrapper

async function miroFetch(path: string, method = 'GET', body?: unknown) {
  const response = await fetch(`https://api.miro.com${path}`, {
    method,
    headers: {
      'Authorization': `Bearer ${process.env.MIRO_ACCESS_TOKEN}`,
      'Content-Type': 'application/json',
    },
    ...(body ? { body: JSON.stringify(body) } : {}),
  });

  if (!response.ok) {
    const error = await response.json().catch(() => ({}));
    throw new Error(`Miro ${method} ${path}: ${response.status} ${error.message ?? ''}`);
  }

  if (response.status === 204) return null; // DELETE returns no body
  return response.json();
}
