API Documentation — ABDM Bridge Gateway

Token type	How to send the token	How HFR ID is provided
Hospital-specific token RECOMMENDED	`Authorization: Bearer {hospital-token}`	Send in the request body — add `"hfr_id": "YOUR_HFR_ID"` to every push request. The gateway validates it matches the HFR ID registered to your API key (`403 HFR_ID_MISMATCH` if wrong). Ask your gateway admin for your token (Admin → Hospital Users → Create User).
Gateway master token	`Authorization: Bearer {gateway-token}`	Must be sent in the request body — add `"hfr_id": "YOUR_HFR_ID"` to every push request. Missing = `400 HFR_ID_REQUIRED`. Unregistered = `403 HFR_ID_NOT_REGISTERED`.

Drug Terminology API How HMS should use CDCI APIs

HMS usage pattern: call /api/v3/drugs/autocomplete during typing, then call /api/v3/drugs/detail after user selection to store canonical identifiers in your HMS record. For Drug Company master sync, call /api/v3/drugs/masters?master=company. All endpoints use hospital Bearer token auth.

Data source clarification: in this gateway, drug endpoints (/api/v3/drugs/autocomplete, /api/v3/drugs/detail, /api/v3/drugs/masters) are served from the imported local CDCI dataset in gateway DB. ABDM upstream proxying applies to ABHA/HIECM flows, not to runtime drug master fetch in this integration.

Important for HMS: do not derive company names only from product records. If your HMS shows No company records found. Use Sync From API to seed company masters from drug payloads., run sync from /api/v3/drugs/masters?master=company and map items[].name as company name and items[].identifier as company code.

Response contract updates: autocomplete/search now include score, matched_on, and exact_match. Detail supports view=canonical (default) and view=hms_fill, including short_formulation for HMS UI fill. Standard errors use { ok, error_code, message, details, request_id }.

GET /api/v3/drugs/autocomplete

Surgery Master API SNOMED CT mapped procedure catalog for OT + billing setup

Implementation strategy: use SNOMED CT as clinical procedure coding baseline. If your billing engine requires additional code sets (for example ICD-10-PCS), keep them in a local mapping table keyed by SNOMED CT.

FHIR export recommendation: surgeries should map to Procedure resource, imaging to DiagnosticReport (often with ImagingStudy), and lab values to Observation.

Health Records API HMS pushes FHIR bundles → gateway stores → ABDM links on demand

Architecture: HMS builds a FHIR R4 Bundle and pushes it via POST /api/v3/records/push. The gateway validates the bundle, stores it, and returns record_id + queue_id — store both in HMS DB. The gateway serves health data to ABDM directly — it never calls back to HMS (NAT-safe architecture). See FHIR Bundle Guide below for complete bundle examples per HI type.

✓ HMS Integration Checklist

#	What HMS must do	Detail
★	Get a hospital-specific API token RECOMMENDED	Ask your gateway admin to create a Hospital User for your hospital (Admin → Hospital Users → Create User). Use the issued token as `Authorization: Bearer {token}`. Your hospital is auto-identified — no `hfr_id` field needed. Tokens can be regenerated or revoked per hospital without affecting others.
1	Generate a unique `care_context_reference` per visit	Use a pattern like `OPD-{YYYYMMDD}-{patientId}` or `IPD-{admissionId}`. Never reuse the same reference — a second push with the same value returns 409 DUPLICATE_RECORD with the existing record info.
2	Build a valid FHIR R4 document bundle	Must be `resourceType:"Bundle"`, `type:"document"`. First entry = `Composition`. Must include `Patient` + at least one clinical resource per HI type. See FHIR Bundle Guide for copy-paste examples.
3	Send correct `hi_type`	Must be one of the 8 ABDM values: `OPConsultRecord`, `PrescriptionRecord`, `DiagnosticReportRecord`, `DischargeSummaryRecord`, `ImmunizationRecord`, `WellnessRecord`, `HealthDocumentRecord`, `InvoiceRecord`
4	Store both `record_id` and `queue_id` from the 201 response	`record_id` — used to fetch/share the record later via GET `/records/{id}` or POST `/records/{id}/share`. `queue_id` — used to match the `record_linked_callback` webhook payload back to the HMS visit record.
5	Handle 409 DUPLICATE_RECORD	Do not treat this as an error. The response contains `existing_record_id` and `first_pushed_at`. Use `existing_record_id` for linking — no need to push again.
6	Handle 422 FHIR_VALIDATION_FAILED	Log the `errors[]` array from the response. Each entry has `code`, `field`, `message`. Fix your bundle builder and retry. The `warnings[]` array is non-blocking — ABDM will still accept the record.
7	Implement `record_linked_callback` webhook endpoint	The gateway fires a signed POST to `{HMS_BASE_URL}/AbdmGateway/record_linked_callback` when a patient links the record. Match on `queue_id`. Verify `X-Eka-Signature`. Return HTTP 200. See Webhooks section.

POST /api/v3/records/push Push FHIR health record from HMS to gateway

Field	Type	Required	Description
`hi_type`	string	required	ABDM HI type: `OPConsultRecord` \| `PrescriptionRecord` \| `DiagnosticReportRecord` \| `DischargeSummaryRecord` \| `ImmunizationRecord` \| `WellnessRecord` \| `HealthDocumentRecord` \| `InvoiceRecord`
`fhir_bundle`	object	required	Valid FHIR R4 Bundle (`resourceType:"Bundle"`, `type:"document"`). See FHIR Bundle Guide.
`care_context_reference`	string	required	Unique visit/episode ID per hospital, e.g. `OPD-2026-05-22-001`. Gateway rejects duplicates (409).
`abha_id`	string	one of*	14-digit ABHA number e.g. `91-5101-6530-5101`
`abha_address`	string	one of*	ABHA address e.g. `patient@abdm`
`care_context_display`	string	optional	Human label shown in PHR app. Auto-generated if omitted: `OPConsultRecord — 2026-05-22 — Dr. Sharma`
`patient_name`	string	optional	Patient full name (stored in shared patient registry)
`local_patient_id`	string	optional	HMS internal patient MRN — stored in hospital sub-table for reference
`visit_date`	date	optional	Date of visit `YYYY-MM-DD`
`doctor_name`	string	optional	Treating doctor name
`department`	string	optional	Department / speciality
`gender`	string	optional	`M` \| `F` \| `O`
`date_of_birth`	date	optional	`YYYY-MM-DD`
`hfr_id`	string	required	Your hospital’s ABDM Facility Registry ID (e.g. `IN0510000828`). Required for all token types. With a hospital-specific API key the value is validated against the HFR ID registered to that key — a mismatch returns `403 HFR_ID_MISMATCH`. With the gateway master token a missing value returns `400 HFR_ID_REQUIRED` and an unregistered value returns `403 HFR_ID_NOT_REGISTERED`.

* At least one of abha_id or abha_address is required.

FHIR Bundle Building Guide How to build a valid FHIR R4 document bundle for each HI type

FHIR R4 — Key Rule: Every bundle must be resourceType:"Bundle", type:"document". The first entry must always be a Composition resource with a subject (Patient reference). A Patient resource must also appear in the bundle entries. The gateway validates all of this and returns a detailed errors[] array if anything is wrong.

8 ABDM HI Types — Required FHIR Resources

ABDM hi_type	Your HMS Record	Required FHIR Resources	Optional / Recommended
`OPConsultRecord`	OPD Consultation	`Composition` + `Patient` + one of: `Condition`, `MedicationRequest`, `Observation`	`Practitioner`, `Organization`, `AllergyIntolerance`, `ServiceRequest`, `Appointment`
`PrescriptionRecord`	OPD Prescription	`Composition` + `Patient` + `MedicationRequest`	`Practitioner`, `Organization`
`DiagnosticReportRecord`	Lab Report / Radiology	`Composition` + `Patient` + `DiagnosticReport`	`Observation` (test results), `ImagingStudy` (radiology), `DocumentReference` (PDF attachment)
`DischargeSummaryRecord`	IPD Discharge	`Composition` + `Patient` + `Encounter` + (`Condition` or `Procedure`)	`Practitioner`, `Organization`, `MedicationRequest`, `CarePlan`
`ImmunizationRecord`	Vaccination record	`Composition` + `Patient` + `Immunization`	`ImmunizationRecommendation`
`WellnessRecord`	Vitals / wellness	`Composition` + `Patient` + `Observation`	Multiple `Observation` entries (BP, SpO2, weight, glucose, etc.)
`HealthDocumentRecord`	Scanned / uploaded doc	`Composition` + `Patient` + `DocumentReference`	Binary attachment embedded in `DocumentReference.content.attachment`
`InvoiceRecord`	Billing / pharmacy invoice	`Composition` + `Patient` + `Invoice`	`Organization` (pharmacy/hospital)

OPConsultRecord - HMS Quick Check (Before Push)

Required for gateway acceptance

Bundle.resourceType must be Bundle
Bundle.type must be document
First entry must be Composition
Bundle must include a Patient entry
For OPConsultRecord, include at least one clinical resource: Condition or MedicationRequest or Observation

Strongly recommended for ABDM quality

Use SNOMED coding for diagnosis (Condition.code.coding)
Use coded medicine concept where possible (MedicationRequest.medicationCodeableConcept.coding)
Include Practitioner and Organization resources
Keep all date-time values in ISO 8601 with timezone

Common HMS mistakes and correct format

// Encounter period start must be ISO date-time:
Wrong: "start": "2026-05-27 05:58:37"
Right: "start": "2026-05-27T05:58:37+05:30"

// Condition should prefer coded SNOMED (not only text):
Better: "code": { "coding": [{ "system": "http://snomed.info/sct", "code": "386661006", "display": "Fever" }], "text": "Fever" }

// Medication should prefer coding + text:
Better: "medicationCodeableConcept": { "coding": [{ "system": "http://snomed.info/sct", "code": "387517004", "display": "Paracetamol" }], "text": "Paracetamol 500 mg tablet" }
                

Note for HMS: For end-to-end automation, use POST /api/v3/records/{id}/link-and-share and poll GET /api/v3/records/{id}/workflow-status. Use /share as manual fallback.

`409`	`DUPLICATE_RECORD`	care_context_reference already pushed	Check `existing_record_id` in response — use that instead of pushing again

HIP-Initiated Linking HMS triggers record linking on patient's ABHA without patient opening PHR app

When to use: After a patient visit, HMS can proactively link prescriptions, lab reports, or discharge summaries to the patient's ABHA directly from the HMS side. No action required from the patient. The flow is: HMS → bridge → ABDM link token → ABDM care-context link → linked ✓.

Implementation sequence: POST /api/v3/hfr/hrp/link (optional setup) → POST /api/v3/hip/link-token → POST /api/v3/hip/link/carecontext → GET /api/v3/hip/link/patient/links → POST /api/v3/hip/link/notify (when metadata changes) → POST /api/v3/hip/link/sms-notify.

ABDM app discovery/link (callback mode): ABDM calls /api/hiecm/user-initiated-linking/v3/patient/care-context/discover, /api/hiecm/user-initiated-linking/v3/link/care-context/init, and /api/hiecm/user-initiated-linking/v3/link/care-context/confirm. HMS should keep ABHA and care-context references accurate in pushed records.

HIP-Initiated Linking — 2-step async flow

POST /api/v3/hip/link-token → async callback /api/v3/hip/token/on-generate-token

HMS sends patient's ABHA details. Bridge calls ABDM /api/hiecm/v3/token/generate-token and returns a request_id immediately. ABDM delivers the JWT link_token asynchronously via the bridge callback (stored in abdm_link_tokens table). Decode the returned link_token_id to use in step 2.

POST /api/v3/hip/link/carecontext → async callback /api/v3/link/on_carecontext

HMS sends care context details with the link_token_id from step 1. Bridge calls ABDM /api/hiecm/hip/v3/link/carecontext with the JWT as X-LINK-TOKEN header. ABDM confirms linking via callback — bridge marks records as linked and fires record_linked_callback webhook to HMS.

Step 1 — Request Link Token

POST https://abdm-bridge.e-atria.in/api/v3/hip/link-token
Authorization: Bearer {api-key}

{
  "abha_address":  "meera.bisht@abdm",
  "abha_number":   "91-5101-6530-5101", // optional
  "name":          "Meera|Bisht",  // First|Last or First|Middle|Last
  "gender":        "F",           // M | F | O
  "year_of_birth": 1990
}

// Response (202) — token arrives asynchronously
{
  "ok": 1,
  "request_id":    "REQ-20260522-abc",
  "link_token_id": 7,   // use in step 2 once delivered
  "message": "Token arrives via on-generate-token callback"
}

Step 2 — Link Care Contexts

POST https://abdm-bridge.e-atria.in/api/v3/hip/link/carecontext
Authorization: Bearer {api-key}

{
  "abha_address":  "meera.bisht@abdm",
  "link_token_id": 7,   // from step 1 response
  "patient_ref":   "HMS-PAT-001",
  "display":       "Meera Bisht",
  "hi_type":       "Prescription",

      "display": "OPD Visit 22 May 2026"
    }
  ]
}

// Response (202)
{ "ok": 1, "request_id": "REQ-20260522-def",
  "message": "Care-context link request sent to ABDM." }

GET /api/v3/hip/link/patient/links

Fetch all care contexts currently linked in ABDM for a patient. Pass ?abha_address= or ?limit=.

GET /api/v3/hip/link/patient/links?abha_address=meera.bisht@abdm

// Response — ABDM patient links data
{ "ok": 1, "data": { /* ABDM patient links response */ } }

POST /api/v3/hip/link/notify & POST /api/v3/hip/link/sms-notify

notify — Push a care-context update notification to ABDM.
sms-notify — Trigger ABDM to send deep-link SMS to patient's registered mobile.

// notify
POST /api/v3/hip/link/notify
{ "abha_address": "meera.bisht@abdm",
  "care_context_reference": "OPD-2026-05-22-001",
  "hi_type": "Prescription",
  "date_of_record": "2026-05-22" }

// sms-notify
POST /api/v3/hip/link/sms-notify
{ "phone_number": "9876543210",
  "hip_name": "City Hospital" }  // optional

ABHA Integration Flows

✅ Gateway Auto-Saves Patient Profile
On every successful aadhaar/verify-otp or mobile/verify-otp, the gateway automatically saves the Aadhaar-verified patient data into its internal Patient Master (abdm_patients table). The response includes two extra fields so HMS can store and use them:

Response Field	Type	Description & HMS Usage
`patient_id`	integer	Gateway's internal patient ID. Store as `abdm_gateway_patient_id` in HMS patient record. Required when pushing health records.
`gateway_patient.abha_id`	string	14-digit ABHA number (no dashes) — store as `abha_number` in HMS
`gateway_patient.abha_address`	string	ABHA address e.g. `91510165305101@abdm` — required for Push ABDM
`gateway_patient.full_name`	string	Aadhaar-verified full name — auto-fill HMS patient name
`gateway_patient.gender`	`M` / `F` / `O`	Gender — auto-fill HMS gender
`gateway_patient.date_of_birth`	`YYYY-MM-DD`	Date of birth — auto-fill HMS DOB
`gateway_patient.mobile`	string	Registered mobile number
`gateway_patient.email`	string	Email address (if available from ABDM)
`gateway_patient.address_line`	string	Address from Aadhaar
`gateway_patient.district`	string	District name
`gateway_patient.state_name`	string	State name
`gateway_patient.pincode`	string	PIN code

Note: Blank fields from ABDM are never overwritten on repeat calls — existing verified data is always preserved.

🆕 Flow 1 — Create ABHA

Patient does not have ABHA yet. Requires Aadhaar number. 2 steps.
Response includes patient_id + gateway_patient with all Aadhaar-verified demographics.

🔗 Flow 2 — Link Existing ABHA

Patient already has ABHA. Requires registered mobile number. 2 steps.
Response includes patient_id + gateway_patient with verified profile for HMS auto-fill.

🆕 Flow 1: Create ABHA via Aadhaar OTP

1 POST /api/v3/abha/aadhaar/generate-otp

{ "aadhaar": "999941057058" }  // plain 12-digit — gateway encrypts it
// Response: { "ok": 1, "data": { "txnId": "c82482fa-...", "message": "OTP sent to ******8717" } }

2 POST /api/v3/abha/aadhaar/verify-otp

{ "txnId": "c82482fa-...", "otp": "123456", "mobile": "9876543210" }

// Response — ABHA created + full patient profile saved in gateway
{
  "ok": 1,
  "request_id": "REQ-20260601-abc",

ABDM → Bridge Callbacks ABDM calls these — no action required from HMS

For HMS Developers: These endpoints are called by ABDM when patients interact with their PHR / ABHA app. You do not call them from HMS. When ABDM calls link/confirm or consent/notify, the bridge automatically fires an outgoing HMAC webhook to your HMS server — see Bridge → HMS Webhooks below.

User-Initiated Linking — Patient links records via PHR app (3-step flow)

POST /api/hiecm/user-initiated-linking/v3/patient/care-context/discover

ABDM asks: "What records does this patient have at this HIP?" Bridge queries abdm_health_records by ABHA ID and calls ABDM /on-discover with matching care contexts.

POST /api/hiecm/user-initiated-linking/v3/link/care-context/init

ABDM sends selected care contexts. Bridge creates a link session in abdm_link_sessions with a linkRefNumber and calls ABDM /on-init.

POST /api/hiecm/user-initiated-linking/v3/link/care-context/confirm

Patient confirms in PHR app. Bridge marks records as linked, calls ABDM /on-confirm, and fires HMS record_linked_callback webhook for each record.

// Example: ABDM sends discover to bridge
POST /api/hiecm/user-initiated-linking/v3/patient/care-context/discover
Authorization: Bearer {abdm-gateway-token}

{
  "requestId": "ABDM-REQ-UUID", "transactionId": "TX-UUID",
  "hip": { "id": "HIP-ID" },
  "patient": { "id": "91-5101-6530-5101" }
}
// Bridge: 202 Accepted, then calls ABDM /on-discover with care contexts

POST /api/hiecm/hip/v3/link/context/notify

ABDM notifies bridge when a HIP-initiated link (via /records/{id}/share) is confirmed. Bridge marks record as linked and fires record_linked_callback to HMS.

{ "notification": {
    "careContext": {
      "patientReference":    "91-5101-...",
      "careContextReference": "OPD-2026-05-18-001"
    }
} }
// Bridge: 202, marks record linked, fires HMS webhook

POST /api/hiecm/data-flow/v3/health-information/hip/request

ABDM requests health data after consent is granted. Bridge acknowledges, fetches records from abdm_health_records, pushes to dataPushUrl, and notifies ABDM of completion.

{ "requestId": "REQ-UUID", "transactionId": "TX-UUID",
  "hiRequest": {
    "consent": { "id": "CONS-UUID" },
    "dateRange": { "from": "2026-01-01T00:00:00Z", "to": "2026-05-18T23:59:59Z" },
    "dataPushUrl": "https://abdm.gov.in/health-info/transfer/..."
  }
}
// Bridge: acknowledges → fetches records → pushes FHIR bundle → notifies ABDM

POST /api/hiecm/consent/v3/hip/notify — Consent notification

ABDM notifies bridge when a patient grants or revokes consent for this HIP.

On GRANTED:

{ "notification": {
    "consentId": "CONS-UUID",
    "status": "GRANTED",
    "patient": { "id": "91-5101-..." }
} }
// Bridge stores consentId on records,
// calls ABDM /hip/on-notify to ack

On REVOKED:

{ "notification": {
    "consentId": "CONS-UUID",
    "status": "REVOKED",
    "revokedAt": "2026-05-18T12:00:00Z"
} }
// Bridge marks records revoked,
// fires HMS consent_revoked_callback

Bridge → HMS Webhooks Bridge calls these on your HMS server

Setup: Configure HMS_WEBHOOK_BASE_URL and HMS_WEBHOOK_SECRET in the gateway .env file. The bridge will POST signed JSON to your HMS server when ABDM events occur. Always verify X-Eka-Signature before processing.

Verify Incoming Webhooks (HMAC-SHA256)

// Every webhook includes this header:
X-Eka-Signature: sha256=<hmac_hex>

// PHP verification
$expected = 'sha256=' . hash_hmac('sha256', file_get_contents('php://input'), getenv('HMS_WEBHOOK_SECRET'));
if (!hash_equals($expected, $_SERVER['HTTP_X_EKA_SIGNATURE'] ?? '')) { http_response_code(401); exit; }

// Python verification
import hmac, hashlib
expected = 'sha256=' + hmac.new(secret.encode(), payload, hashlib.sha256).hexdigest()
assert hmac.compare_digest(expected, request.headers['X-Eka-Signature'])

POST {HMS_BASE_URL}/AbdmGateway/record_linked_callback

Fired when a care context record is successfully linked to a patient's ABHA in ABDM (user-initiated or HIP-initiated).

// Payload
{
  "queue_id":               "REC-20260518-a1b2c3d4",
  "care_context_reference": "OPD-2026-05-18-001",
  "abha_id":               "91-5101-6530-5101",
  "abha_address":          "meera.bisht@abdm",
  "record_type":           "OPConsultRecord",  // ABDM hi_type value
  "linked_at":             "2026-05-18 11:45:00",
  "source": "user_initiated"  // or "hip_initiated"
}
// Expected response from HMS: HTTP 200

POST {HMS_BASE_URL}/AbdmGateway/consent_revoked_callback

Fired when a patient revokes consent. Bridge also marks all linked records for this ABHA as revoked automatically.

// Payload
{
  "consent_handle": "CONS-UUID",
  "abha_id":        "91-5101-6530-5101",
  "revoked_at":     "2026-05-18T12:00:00Z"
