# Milestone 4

> Healthcare Professional Registry (HPR), Health Facility Registry (HFR), and Onboarding flows for ABDM integration.

## M4 Flow — Registries & Onboarding

***

## 1. Healthcare Professional Registry (HPR)

### Via Aadhaar Authentication

  A["Get Aadhaar OTP"] --> B["Verify Aadhaar OTP"]
  B --> C["Verify Mobile"]
```

### HPR ID Creation

```mermaid theme={null}
flowchart LR
  A["Get HPR Info"] --> B{"HPR ID exists?"}
  B -->|Yes| E["✅ Done — Skip creation"]
  B -->|No| C["Suggest IDs"]
  C --> D["Create HPR"]
```

### Mobile Login *(alternative entry)*

```mermaid theme={null}
flowchart LR
  A["Get Mobile OTP"] --> B["Verify Mobile OTP"]
  B --> C["Check If HPR is Available"]
```

<Note>
  Use **Get Aadhaar OTP → Verify → Verify Mobile** for first-time registration. Use **Get Mobile OTP → Verify Mobile OTP** for returning professionals logging in via mobile.
</Note>

## 2. Health Facility Registry (HFR)

```mermaid theme={null}
flowchart LR
  A["Search HFR"] --> B{"Facility exists?"}
  B -->|Yes| D["Link HFR"]
  B -->|No| C["Onboard HFR"]
  C --> D
```

<Note>
  Always **Search HFR** first. If the facility already exists in the ABDM registry, skip onboarding and go directly to **Link HFR**.
</Note>

***

## 3. Onboarding to Eka

```mermaid theme={null}
flowchart LR
  A["Create HPR ID on ABDM portal"] --> B["Register Facility HFR ID"]
  B --> C["Software Linkage via Eka Bridge ID"]
  C --> D["Onboard to Eka ✅"]
```

<Note>
  This is a **one-time setup** flow. Once the HPR ID and HFR ID are created and registered on the ABDM portal, use the **Software Linkage** step from the facility dashboard to connect via the Eka Bridge ID, then call the Onboard API to complete integration.
