ABHA SDK Implementation

This guide provides everything you need to integrate the ABHA SDK into your application.

Overview

The ABHA SDK allows you to integrate Create ABHA, Login with ABHA flows into your healthcare applications. It provides:

Create ABHA: Create a new ABHA using Mobile or Aadhaar
Login with ABHA: Login with ABHA address[PHR Address], ABHA number, Adhaar number or Mobile number linked to your ABHA into your healthcare application.

Installation

Prerequisites

A modern web browser.
Your domain must be whitelisted with Eka Care to avoid CORS(Cross-Origin Resource Sharing) error. (Contact Eka Care to request API access and domain whitelisting.)
A valid HTML container element where the SDK will mount.

Setup

Add the following HTML and script tags to your webpage:

         // Pass access token and oid
          data: {
            accessToken: "<your_access_token>", // Pass the access token you have
            oid: "<your_oid_if_available>", // Pass if you have the OID

          },

          // Success callback
          onSuccess: async (params) => {
            console.log("ABHA flow completed successfully:", params);
            // Example: Store ABHA data in your app
            dispatch({
              type: "set-only-healthid-data",
              healthIdData: formatter(params.response.data),
            });
          },

          // Error callback
          onError: (params) => {
            console.error("ABHA flow failed:", params);
            if (window.EkaAbha) {
              window.EkaAbha.onAbhaFailure(JSON.stringify(params));
            }
          },
        });
      }
    </script>

Core Functions

1. initAbhaApp

Initializes and renders the ABHA SDK in your specified container. Parameters:

Name	Type	Required	Description
`containerId`	`string`	✅	The HTML element ID where the SDK will mount.
`data`	`{ accessToken: string; oid?: string; orgIcon?: string; linkToOrgIcon?: string }`	⚙️ Optional	Configuration data for initializing the ABHA flow. - accessToken: Pass the access token you have. - oid: Pass if available. - orgIcon: URL of your organisation’s icon to display inside the SDK url should start with https://. - linkToOrgIcon: URL of the icon representing “Link ABHA to your organisation” url should start with https://.
`onSuccess`	`(params: AbhaSuccessParams) => void`	✅	Triggered when the user successfully creates or logs in to ABHA.
`onError`	`(params: AbhaErrorParams) => void`	✅	Triggered when an error occurs during the ABHA flow.

Example:

window.initAbhaApp({
  containerId: "sdk_container",
  data: {
    accessToken: "your_access_token_here",
    oid: "optional_oid_here",
    orgIcon: "url_of_your_org_icon",
    linkToOrgIcon: "url_of_image_to_link_abha_to_your_org",
  },
  onSuccess: (params) => {
    console.log("ABHA created successfully!", params);
  },
  onError: (error) => {
    console.error("ABHA flow failed:", error);
  },
});

Callback Parameters

onSuccess Callback

The onAbhaSuccess callback is triggered when the ABHA flow completes successfully. It returns verified user details and tokens, which can be used to log in or continue the user’s session. Callback Signature:

onSuccess: (params: TOnAbhaSuccessParams) => void;

Type Definitions

export type TOnAbhaSuccessParams = {
  response: TAuthVerifyV2Response;
};

export type TAuthVerifyV2Response = {
  skip_state: number;
  method: AUTH_METHOD;
  data?: {
    tokens: {
      sess: string;
      refresh: string;
    };
    profile: TProfileRecord;
  };
  txn_id: string;
  error?: {
    code: number;
    message: string;
  };
};

Parameters

Key	Type	Description
`response`	`TAuthVerifyV2Response`	The complete ABHA verification response, containing session tokens, user profile, and transaction details.

Example:

const onSuccess = (params) => {
  console.log("ABHA Success:", params.response);

  const abhaNumber = params.response.data?.profile?.abha_number;
  const userName = params.response.data?.profile?.name;

  alert(`Welcome ${userName}! Your ABHA Number: ${abhaNumber}`);

  // Optionally pass data to native bridge
  if (window.EkaAbha) {
    window.EkaAbha.onAbhaSuccess(JSON.stringify(params));
  }
};

onError Callback

The onError callback is triggered whenever an ABHA flow fails or is interrupted. It provides details about the failure through structured parameters, allowing you to handle or forward the error appropriately (for example, to native apps or monitoring tools). Callback Signature:

onError: (params: TOnAbhaFailureParams) => void;

Type Definitions

type TOnAbhaFailureParams = {
  error?: string;
  response?: TAuthVerifyV2Response;
};

export type TAuthVerifyV2Response = {
  skip_state: number;
  method: AUTH_METHOD;
  data?: {
    tokens: {
      sess: string;
      refresh: string;
    };
    profile: TProfileRecord;
  };
  txn_id: string;
  error?: {
    code: number;
    message: string;
  };
};

Parameters

Key	Type	Description
`error`	`string?`	Short description of the failure or error message.
`response`	`TAuthVerifyV2Response?`	Partial or full API response object returned from ABHA services.

Example:

const onError = (params) => {
  console.error("ABHA Error:", params);

  if (params.response?.error?.code === 1001) {
    alert("Authentication failed. Please try again.");
  } else if (params.error === "NETWORK_ERROR") {
    alert("Please check your internet connection.");
  } else {
    alert("Something went wrong. Please retry.");
  }

  // Forward the error to native handler if available
  if (window.EkaAbha) {
    window.EkaAbha.onAbhaFailure(JSON.stringify(params));
  }
};

Suggest Handling -Always log the full error response (params) for debugging. -Display friendly error messages for known error.code values. -If params.response is present, inspect response.error.message for more detail. -If integrating with native apps, forward the serialized error object:

window.EkaAbha.onAbhaFailure(JSON.stringify(params));

Container Styling

Ensure your container has sufficient space:

<div
  id="sdk_container"
  style="width: 100%; height: 600px; border: 1px solid #ddd;"
></div>

Troubleshooting

Common Issues

1. SDK Not Rendering

Problem: Nothing appears in the container. Solution:

Ensure containerId matches an existing HTML element.
Verify the SDK JS and CSS are correctly loaded.
Check browser console for errors.

2. Callback Not Triggered

Problem: onSuccess or onError isn’t firing. Solution:

Make sure both callbacks are passed as valid functions.
Avoid race conditions (e.g., calling before SDK fully loads).

3. Styling Issues

Problem: SDK content appears misaligned or clipped. Solution:

Give your container a fixed height (e.g., 600px).
Ensure no parent element uses overflow: hidden.
