How to Integrate Lovable with Blackboard

Before storing credentials in Lovable, you must register your application as an API integration in Blackboard's System Admin panel. Blackboard uses registered integrations to control which applications can access the API and with what permissions. Log in to Blackboard as a System Administrator. Navigate to System Admin → Integrations → REST API Integrations. Click 'Create Integration'. Fill in the registration form: - Application ID: a unique identifier for your integration (e.g., lovable-custom-portal) - Learn User: a dedicated Blackboard user account that your integration will act as — create a new non-admin user with appropriate role permissions (typically a system role with read access to courses, grades, and user data) - End User Access: set to 'Yes' if your integration needs to act on behalf of individual users; set to 'No' for system-level access only - Authorized to Act as User: set appropriately based on your use case - Description: describe your integration purpose Click 'Submit'. Blackboard generates an Application ID (client_id) and Application Secret (client_secret). The secret is shown only once — copy it immediately and store it somewhere safe before leaving this page. For the Learn User associated with the integration, ensure that user has the appropriate role. For a read-only dashboard, create a user with a custom role that allows Read access to: Courses (content, grade center), Users (profiles, enrollment), and Announcements. This principle of least privilege limits what the integration can do if the credentials are ever compromised. The Blackboard REST API base URL for your instance will be: https://your-blackboard-domain.edu/learn/api/public

Store your Blackboard API credentials and instance URL in Lovable's encrypted Secrets panel. These values are accessed only by your Edge Function and are never visible in frontend code or repositories. In Lovable, click the '+' icon at the top of the editor to open the Cloud panel. Click the Secrets tab. Click 'Add new secret' and add: - Name: BLACKBOARD_CLIENT_ID — Value: your Application ID from the Blackboard REST API integration registration - Name: BLACKBOARD_CLIENT_SECRET — Value: your Application Secret from the registration (the value shown only once) - Name: BLACKBOARD_BASE_URL — Value: your Blackboard instance URL without trailing slash (e.g., https://blackboard.yourschool.edu) The BLACKBOARD_BASE_URL is not a secret per se (it is the public URL of your school's Blackboard), but storing it here alongside the credentials makes the Edge Function configuration cleaner and allows URL changes without code deployments. Blackboard's OAuth2 token endpoint is at {BLACKBOARD_BASE_URL}/learn/api/public/v1/oauth2/token. The client credentials flow requires a POST to this endpoint with Basic auth (Base64-encoded client_id:client_secret) and grant_type=client_credentials in the request body. The access token returned is typically valid for one hour. Lovable's security system blocks approximately 1,200 hardcoded API keys from code per day. Using Cloud → Secrets ensures your Blackboard credentials are encrypted at rest and only accessible from Edge Functions via Deno.env.get().

Build the Edge Function that manages OAuth2 token acquisition and caching, then proxies API requests to Blackboard's REST API. The function handles the full token lifecycle: requesting a new token when none is cached, caching it for its validity period, and refreshing it when expired. Paste this prompt into Lovable's chat: 'Create a Supabase Edge Function at supabase/functions/blackboard-api/index.ts. Read BLACKBOARD_CLIENT_ID, BLACKBOARD_CLIENT_SECRET, and BLACKBOARD_BASE_URL from Deno.env. The function should: (1) Cache an OAuth2 access token in module-level state by POSTing to {BASE_URL}/learn/api/public/v1/oauth2/token with Basic auth (client_id:client_secret in base64) and body grant_type=client_credentials. (2) Accept POST requests with body { endpoint: string, method: string, params?: object, body?: object }. (3) Call {BASE_URL}/learn/api/public/{endpoint} with Authorization: Bearer {token}. (4) Return the Blackboard API response as JSON with CORS headers.' Blackboard's REST API endpoints follow the pattern /learn/api/public/v1/{resource}. Common paths: - GET /v1/courses — list all courses - GET /v1/courses/{courseId} — single course - GET /v1/courses/{courseId}/contents — course content items - GET /v1/courses/{courseId}/gradebook/columns — grade columns - GET /v1/courses/{courseId}/gradebook/users/{userId} — user grades - GET /v1/courses/{courseId}/users — enrolled users - GET /v1/users — list all users - GET /v1/users/{userId}/courses — user enrollments

With the Edge Function handling authentication, build React components that display Blackboard course and grade data in a modern, clean interface. Paste this prompt into Lovable's chat: 'Create a BlackboardDashboard React component. Fetch all courses using the blackboard-api Edge Function with endpoint v1/courses and params { fields: id,name,courseId,enrollmentCount }. Display courses as sidebar navigation items. Clicking a course loads: (1) Course info section with name, course ID, and enrollment count. (2) Grade book section: call endpoint v1/courses/{courseId}/gradebook/columns to list grade columns (assignments). For each column, show: name (title), due date, points possible. (3) For student users, also fetch v1/courses/{courseId}/gradebook/users/{userId}/columns to show the student own grades. Color-code grades: green for A (90%+), blue for B (80-89%), yellow for C (70-79%), orange for D (60-69%), red for F (below 60%).' Blackboard course objects include: id (internal UUID-like ID), courseId (the human-readable course identifier like 'MATH101-SP2026'), name, description, and organization (boolean for whether it is an organization/group rather than a course). Blackboard grade column objects include: id, name, displayName, displayGrade (point-based, percentage, letter, or complete/incomplete), score (maximum points), dueDate, gradeNotationId, and possible (boolean for whether the column is gradable). For student grade records, the response includes: score (earned points), displayGrade (formatted grade string), and status (Attempted, NotAttempted, NeedsGrading, Graded). Use the displayGrade field for showing grades to students as it respects Blackboard's configured grade display format.

Extend the dashboard with course content browsing and announcement display — two features that are particularly poorly implemented in Blackboard's native UI that users appreciate seeing improved. Paste this prompt into Lovable's chat: 'Add two more tabs to the BlackboardDashboard for the selected course: (1) Content tab: call blackboard-api Edge Function with endpoint v1/courses/{courseId}/contents to get the top-level content items. Each item has a type (Document, Folder, Forum, Assignment, etc.) and a title. For Folder items, show an expand arrow that fetches v1/courses/{courseId}/contents/{contentId}/children when clicked. Render Document items with a View link and Assignment items with due date and points. (2) Announcements tab: call v1/courses/{courseId}/announcements to list course announcements sorted by draft_at descending. Show each announcement with title, body (rendered as HTML safely), author name, and posted date.' Blackboard content types include: Document (read content), Assignment (gradable submission), Forum (discussion board), Folder (container), SCORM (packaged content), and ExternalLink (outbound link). Show appropriate icons and actions for each type. For rendering Blackboard announcement HTML bodies, use a sanitized dangerouslySetInnerHTML approach. Blackboard HTML is generally clean but may contain old-style HTML attributes. DOMPurify is the recommended sanitizer — add it via Lovable: 'Add the DOMPurify package and use it to sanitize HTML strings before rendering with dangerouslySetInnerHTML.'
