ABDM M1: "Find ABHA by Mobile" Complete Profile Flow +- **Challenge:** Previously, after searching linked ABHA numbers via mobile OTP in Step 1, selecting an ABHA ID required a redundant "Verify ABHA ID" step to retrieve the patient's full demographic profile (name, gender, DOB, address, photo, etc.). +- **Solution:** + - Integrated direct verification API flow upon ABHA profile selection. + - Automatically loads and populates the complete KYC details (full name, gender, DOB, mobile, address, ABHA address, profile photo base64) directly into the patient registration form. + - Fixed multi-step wizard state indicators in the registration modal. + +--- + +### 2. ABDM M2: User-Initiated Linking Architecture & Implementation +- **Context & Observation from ABDM Team:** + > *"M2: User initiated linking: There is understanding gap in user initiated linking flow.* + > *FLOW: Patient must be registered without ABHA details in your system -> Records will be created in your system -> User will link them on their own end using PHR app."* +- **Network Topology Architecture:** + - `HMS (behind NAT on premise/VPN)` $\longleftrightarrow$ `ABDM Bridge (Live in Cloud)` $\longleftrightarrow$ `ABDM Gateway` $\longleftrightarrow$ `PHR App (e.g. ABHA App, Aarogya Setu)` + - Each HMS has a unique domain/subdomain reachable by the Bridge via VPN or cloud tunnel. +- **HMS Implementation:** + - **Database Migration:** `2026-09-09-000003_CreateAbdmLinkTransactions.php` creates table `abdm_link_transactions` (tracks `transaction_id`, `patient_reference`, `care_context_reference`, `auth_mode`, `otp_hash`, `expiry_at`, `status`). + - **Discovery Endpoint:** Handles `/v3/hip/patient/care-context/discover` from the Bridge: + - Matches patient by demographic data (Mobile number, Name, Gender, Year of Birth). + - Returns patient UHID (`p_code`) and all unlinked care contexts (OPD visits, IPD admissions, Lab investigations, Pharmacy dispense records). + - **Linking Initiation (`/v3/hip/link/init`):** + - Generates authentication OTP or confirms direct link. + - **Linking Confirmation (`/v3/hip/link/confirm`):** + - Verifies OTP and permanently registers link in `abdm_link_transactions` and updates `patient_master.abdm_linked_at`. + - **Bridge Walkthrough Verified:** Analyzed and approved the ABDM Bridge Walkthrough specification (`ABDM_BridgeSide_M2_workthrouh.txt`). + +--- + +### 3. M3 HIU Consent Requests List: Live Server 500 Error Resolution +- **Issue:** On the live server (`https://demo.e-atria.net`), opening **"ABHA Patient Request List"** triggered: + `Failed to load: Unable to load consent requests.` + HAR log showed: `GET https://demo.e-atria.net/AbdmHiu/patient_request_list_data?q=&status=` returning `500 Internal Server Error` with empty response body `""`. +- **Root Cause Analysis:** + 1. **Memory Exhaustion on Decrypted FHIR Bundles:** `abdm_hiu_workflows` stores multi-megabyte decrypted base64 bundles in `response_json` for `data_fetch` and `hi_data_push_callback`. Querying 2000 rows exhausted PHP memory (`128M`), triggering a fatal memory limit error. + 2. **Hardcoded Column Selection:** The query hardcoded 17 columns in `SELECT` without checking table fields. Any schema difference on the remote database caused a fatal `DatabaseException` (`Unknown column in field list`). + 3. **Array-to-String Cast Warnings:** In PHP 8.2+, accessing nested payload objects (`requester`, `purpose`, `expiry`, `hi_types`) that arrived as associative arrays triggered `Array to string conversion` warnings, which CodeIgniter converted to fatal `ErrorException`s. + 4. **Missing Exception Handling:** `AbdmHiu::patientRequestListData()` lacked a `try ... catch` block, causing CI in production to respond with HTTP 500 and empty content. + 5. **Column Mismatch on `patient_master`:** Looked for `p_mobile` instead of actual columns `mphone1` and `mphone2`. +- **Changes Applied & Tested:** + - `app/Controllers/AbdmHiu.php`: Wrapped in `try ... catch (\Throwable $e)`, added error logging, and guaranteed clean JSON response. + - `app/Libraries/Abdm/ConsentSessionListService.php`: + - Dynamically queries only existing columns in `abdm_hiu_workflows`. + - Masks large JSON fields at the SQL level (`CASE WHEN operation IN ('data_fetch', 'hi_data_push_callback') THEN NULL ELSE response_json END`). + - Added `extractScalarString()` and safe array parsing. + - Updated phone resolution (`mphone1`, `mphone2`) and cleaned full names. + - Adopted stable session correlation algorithm matching `Patient.php`. + - `app/Views/abdm/patient_request_list.php`: Enhanced fetch error handling to display HTTP status codes cleanly. +- **Git Commit:** `b89bace` pushed to `origin/main`. + +--- + +## ⚙️ Live Server Deployment Step + +When deploying to `demo.e-atria.net`: + +```bash +git pull origin main +php spark cache:clear +``` + +--- + +## 📂 Key Files & References + +| File | Purpose | +| :--- | :--- | +| `app/Controllers/AbdmHiu.php` | Controller for HIU Consent Request List & Document fetch | +| `app/Libraries/Abdm/ConsentSessionListService.php` | Core service computing global consent sessions and status | +| `app/Views/abdm/patient_request_list.php` | UI view for ABHA Patient Request List table and modal | +| `app/Database/Migrations/2026-09-09-000003_CreateAbdmLinkTransactions.php` | M2 user-initiated linking database table migration | +| `ABDM_BridgeSide_M2_workthrouh.txt` | Detailed specification for ABDM Bridge user-initiated linking | +| `app/Controllers/Patient.php` | Per-patient OPD profile ABDM consent and linking management | + +--- + +## 📋 Open Items / Next Steps for Tomorrow + +1. **Live Verification on `demo.e-atria.net`:** + - Verify that **ABHA Patient Request List** loads all historical requests smoothly without error. +2. **M2 User-Initiated Linking End-to-End Test:** + - Create an unlinked patient in HMS. + - Add an OPD visit and a prescription/document. + - Use ABHA/PHR App on Sandbox to discover records using mobile number and complete linking with OTP. + - Verify care context shows as linked on both Bridge and HMS. +3. **M2 Pull & Push Sync Verification:** + - Verify automatic push of newly created OPD prescriptions and diagnostic reports for linked care contexts.
