# Health Data Received from HIP

Webhook event is sent when an external HIP pushes encrypted health data to your HIU.

The Health Information User (HIU) can initiate a consent request through the [Consent-API](/api-reference/user-app/abdm-connect/consents/consent-create) to get care context data. Once consent is validated, the Health Information Provider (HIP) sends the encrypted health data to the HIU.

### Request

**Headers:**

* `Eka-Webhook-Signature`: `<Eka Webhook Signature>`  [Refer: Webhook Signature](/api-reference/connect/webhooks/webhook-signature)
* `Content-Type`: `application/json`

**Body:**

```json theme={null}

### Field Descriptions

* **`data`**: Contains additional details related to the event.
  * **`consent_id`**: Consent id for the data transfer
  * **`transaction_id`**: Transaction id for the data flow
  * **`entries`**: List of care contexts with encrypted fhir data
  * **`key_information`** : Contains the cryptographic key material and related parameters required for secure ECDH-based key exchange between HIU and HIP.
    * `crypto_alg` The cryptographic algorithm used for key exchange (e.g., "ECDH").
    * `curve` The elliptic curve used in ECDH key generation (e.g., "Curve25519", "P-256").
    * `dh_public_key` Object containing the HIU’s public key and related metadata:
      * `expiry` The expiration timestamp (in ISO 8601 format) indicating how long the public key is valid.
      * `parameters` Additional parameters related to the ECDH key (optional or curve-specific).
      * `key_value` The base64-encoded public key value generated by the HIU.
    * `nonce` A 32-byte random nonce (Base64-encoded) generated by the HIU, used to ensure uniqueness in the session key derivation.
