How to Integrate Lovable with Edmodo

Before building anything, verify that Edmodo's API is accessible and obtain current credentials. Edmodo's developer platform (developers.edmodo.com) is where API applications are registered and documentation is hosted. To register an application and obtain credentials: Go to developers.edmodo.com and sign in with your Edmodo account. Navigate to the 'My Apps' section. Click 'Create New App'. Fill in: App Name, Description, Website URL, and your Callback URL (for OAuth2 — use your Lovable app's deployed URL followed by /auth/edmodo/callback). Submit the application registration. You receive an Application Key (client_id) and Application Secret (client_secret). Edmodo's API uses OAuth2 for user-specific data. The authorization flow: redirect users to https://api.edmodo.com/oauth/authorize?response_type=code&client_id={id}&redirect_uri={callbackUrl}&scope=basic groups posts assignments. After authorization, exchange the code for an access token at https://api.edmodo.com/oauth/token. For teacher/admin-level system access, Edmodo also provides an API key for direct integration without per-user OAuth — check the Edmodo developer documentation for whether this is still supported. Critical note: Edmodo's API underwent changes following the 2022 business restructuring. Some endpoints that were previously documented may return 404 or 403. Test the endpoints you plan to use (groups, posts, assignments, badges) against your specific Edmodo instance before committing to this integration path. If API access is unavailable, the Supabase-centric data approach (manual curation + self-reporting) described in the Codecademy tutorial is a viable fallback.

Store your Edmodo OAuth2 credentials in Lovable's Cloud → Secrets panel. In Lovable, click the '+' icon at the top of the editor to open the Cloud panel. Click the Secrets tab. Add: - Name: EDMODO_CLIENT_ID — Value: your Edmodo application key (client ID) - Name: EDMODO_CLIENT_SECRET — Value: your Edmodo application secret For the OAuth2 flow, you will also need to store user access tokens after the teacher or parent authorizes the app. Add a placeholder secret: - Name: EDMODO_ACCESS_TOKEN — Value: (leave empty for now — this will be populated per user in the Supabase user profiles table after OAuth authorization) The user-level access tokens should be stored per-user in your Supabase user profiles table, not as a single shared secret. The Edge Function will read the current user's Edmodo access token from Supabase (passed as a parameter from the frontend) rather than from Cloud → Secrets. For a simpler single-teacher or single-school deployment, you can store a single admin-level access token as EDMODO_ACCESS_TOKEN and use it for all API calls. This avoids implementing the full per-user OAuth flow at the cost of flexibility.

Build the Edge Function that proxies requests from your Lovable frontend to the Edmodo REST API. Edmodo's API uses Bearer token authentication with user-level access tokens. Paste this prompt into Lovable's chat: 'Create a Supabase Edge Function at supabase/functions/edmodo-api/index.ts. The function accepts POST requests with body { endpoint: string, method: string, accessToken: string, params?: object }. Read EDMODO_CLIENT_ID from Deno.env (for reference, not used in per-request auth). Call https://api.edmodo.com/{endpoint}?access_token={accessToken} with the Edmodo access token. For GET requests, add params as additional query parameters. Return the Edmodo API response as JSON with CORS headers. Handle Edmodo API error responses (they include error and error_description fields) by returning them with appropriate HTTP status codes.' Edmodo's REST API base URL is https://api.edmodo.com. The access_token can be passed as a query parameter (?access_token=xxx) or as a Bearer token in the Authorization header — both patterns are documented by Edmodo. Using query parameter is simpler for GET requests. Common Edmodo API endpoints: - GET /me — current user profile - GET /groups — user's groups (classes) - GET /groups/{id}/posts — posts in a group - GET /groups/{id}/members — group members - GET /assignments — user's assignments - GET /users/{userId}/badges — user's badges - GET /posts/{postId}/replies — replies to a post

With the Edge Function deployed, build the React components that display Edmodo classroom data. The core view for a parent portal is the classroom activity feed — posts, assignment notifications, and badge awards. Paste this prompt into Lovable's chat: 'Create a ClassroomFeed React component. It accepts an accessToken prop and a groupId prop. Call the edmodo-api Edge Function with endpoint groups/{groupId}/posts, method GET, the accessToken, and params { per_page: 20, page: 1 }. Render posts in a chronological feed showing: teacher avatar and name (from post.creator), post time ago (relative time from post.created_at), post content text, any attached files with icons, and assignment details (if post.links[0].type === assignment: show due date and point value). For new assignment posts, show a highlight card with red ASSIGNMENT badge and due date. Add a Load More button for subsequent pages.' Edmodo post objects include: id, type (post, reply, assignment), content (text body), creator (user object with name and avatar_url), created_at, to (groups the post is directed to), and links (array of attached content with type and details). For parent portals, the most valuable content is assignments (so parents know what's due) and grade feedback (so parents see how their child performed). Prioritize these in your UI over general discussion posts. For badge display, GET /users/{userId}/badges returns an array of badge objects with name, description, image_url, and awarded_at. Display them as an achievement wall with badge thumbnails sorted by most recently awarded.

Complete the integration with the OAuth2 flow for user authorization and group navigation so teachers or parents can connect their Edmodo account to your Lovable app. Paste this prompt into Lovable's chat: 'Add a Connect Edmodo Account flow. (1) Create a Connect Edmodo button that redirects to https://api.edmodo.com/oauth/authorize?response_type=code&client_id={EDMODO_CLIENT_ID}&redirect_uri={callbackUrl}&scope=basic+groups+posts+assignments. (2) Create an Edge Function at supabase/functions/edmodo-auth/index.ts that receives the OAuth2 callback with the code parameter, exchanges it for tokens at https://api.edmodo.com/oauth/token, stores the access_token and refresh_token in the user's Supabase profile, then redirects to the app dashboard. (3) After connection, fetch the user's groups using the edmodo-api Edge Function (endpoint groups) and display them as a group selector. Show a Connected badge with the Edmodo username.' The OAuth2 token exchange requires a POST to https://api.edmodo.com/oauth/token with: grant_type=authorization_code, code={authCode}, client_id, client_secret, and redirect_uri. Store the returned access_token and refresh_token in the Supabase user profiles table. After the initial connection, build a group selector showing all the user's Edmodo groups (classes). When a teacher selects a group, the ClassroomFeed component loads posts for that group using the stored access token.
