# July Updates

## New Features

### Message-Level Encryption (MLE)

![MLE](https://mintcdn.com/methodfinancial/zaEy2Zf5mLkHDuX_/images/enc.jpg?fit=max\&auto=format\&n=zaEy2Zf5mLkHDuX_\&q=85\&s=b1c84dbcb2fd516ef856acb208f1d5bf)

We’ve added support for end-to-end encryption of sensitive data transmitted between your application and Method’s API, available to everyone. Here’s what’s new:

* **Hybrid Encryption:** Uses AES-GCM (for payload encryption) and RSA-OAEP-256 (for key encryption) to ensure confidentiality even if network traffic is intercepted.

* **Public Key Registration:** Register your RSA public key with Method via a `.well-known` endpoint or direct upload.

* **Encrypted Requests & Responses:** Send encrypted payloads using the `Method-MLE: jwe` header; Method encrypts responses using your public key.

* **Key Management:** Support for key rotation, deprecation, deletion, and webhook notifications for Method key changes.

You can find a [quickstart guide here](https://docs.methodfi.com/reference/message-level-encryption.md#quickstart). For more information, please refer to the [Message Level Encryption documentation](https://docs.methodfi.com/reference/message-level-encryption.md).

### Card Brand API

![Card Brands](https://mintcdn.com/methodfinancial/zaEy2Zf5mLkHDuX_/images/card-art.jpg?fit=max\&auto=format\&n=zaEy2Zf5mLkHDuX_\&q=85\&s=fc0dfa25f823766bc443936771695402)

We’ve expanded the Card Brand object to provide a more structured format with richer brand details — making it easier to identify, display, and integrate specific card products with consistent issuer, network, and branding data.

**Key Changes**:

* `network` and `issuer` are now nested inside each brand object.
* Added `card_product_id`, `description`, and `type` fields.
* Removed `last4` and `shared` fields.

### Card Products API

We've added a new `Card Products` directory accesible via our API allowing you to retrieve all `Card Brand` objects associated with a given `Card Product`.

## Improvements

### Connect API

We now support asynchronous Connect requests. You'll receive a `connect.available` webhook when an Async Connect is completed. Async Connect requests can be created by either:

* Setting the `Prefer: respond-async` header
* Specifying `products` and / or `subscriptions` in the request body

The Connect object will now include `requested_products` and `requested_subscriptions` fields in the response body.

> [accordion] Example Request
>
> ```bash cURL theme={null}
> curl https://production.methodfi.com/entities/ent_qKNBB68bfHGNA/connect \
>   -X POST \
>   -H "Prefer: respond-async" \
>   -H "Content-Type: application/json" \
>   -H "Authorization: Bearer sk_WyZEWVfTcH7GqmPzUPk65Vjc" \
>   -d '{
>     "requested_products": ["card_brand"],
>     "requested_subscriptions": ["card_brand"]
>   }'
> ```

> [accordion] Example Response after Connect is completed
>
> ```json theme={null}
> {
>   "id": "cxn_4ewMmBbjYDMR4",
>   "entity_id": "ent_qKNBB68bfHGNA",
>   "status": "completed",
>   "accounts": [

>     "acc_MLPKh9gQDDbT8",
>     "acc_LbXE8wVYJLrKt",
>     "acc_J3P9fayDFjpAy",
>     "acc_eFFRV9zmpLREK"
>   ],
>   "requested_products": ["card_brand"],

>   "error": null,

>   "updated_at": "2024-04-12T14:56:46.645Z"
> }
> ```

For more information, please refer to the [Connect API](https://docs.methodfi.com/reference/entities/connect/overview.md).

### Webhook API

We've added a new `refs` object to webhook payloads. This object contains the `entity` ID of the Entity that the webhook is related to.

> [accordion] Example Webhook Payload
>
> ```json theme={null}
> {
>   "webhook_id": "whk_cSGjA6d9N8y8R",
>   "id": "pmt_zR3nJG3c99P3X",
>   "type": "payment.update",
>   "op": "update",
>   "path": "/payments/pmt_zR3nJG3c99P3X",
>   "event": "evt_knqJgxKUnqDVJ",
>   "refs": {
>     "entity": "ent_qKNBB68bfHGNA"
>   }
> }
> ```

We have also added the following new webhooks:

* `card_brand.available`
* `connect.available`
* `method_jwk.create`
* `method_jwk.update`

For more information, please refer to the [Webhooks API](https://docs.methodfi.com/reference/webhooks/overview.md).

### Entity and Account Products

The `product_id` field in the `Product` object and the Retrieve endpoint are now deprecated. We've added the `latest_successful_request_id` field to the `Product` object. This field will contain the ID of the most recently successful Product resource.

For more information, please refer to the [Entity Products API](https://docs.methodfi.com/reference/entities/products/overview.md) and [Account Products API](https://docs.methodfi.com/reference/accounts/products/overview.md).
