> **Description:** Login Connect enables merchants to do card enrolment and card linking through the Login flow.

# Login Connect

**Under development**

This feature is under development, so changes may occur.

*Login Connect* enables a merchant to do **card enrolment** and **card linking**. Login Connect builds on the standard Login flow, a user logs
in with Vipps  or MobilePay  and consents to share their cards with the merchant.

## How to

Login Connect is an extension of the standard Login flow, so the integration is mostly the same as a regular Login integration.
The main difference is that the merchant must request the `paymentSourceReferences` scope to trigger the Login Connect flow.

The user will be prompted to consent to share their cards with the merchant during the login flow:

Login Connect consent screens: an intro screen explaining the benefits ("Get benefits when you shop"), followed by a screen where the user selects which cards and accounts to share.

The userinfo response will include a `payment_sources_details` array, where each entry has an
`external_payment_source_id` identifying a payment source the user consented to share. For example:

```json
{
    "sub": "126684df-c056-4625-821d-f2905febe3f9",
    "payment_sources_details": [
        {
            "external_payment_source_id": "a91b26e4-a833-4618-84f8-c5e2a94545bb"
        },
        {
            "external_payment_source_id": "0736ffb6-7b12-4041-a3fd-a75ec13451ec"
        },
        {
            "external_payment_source_id": "54f1a590-11f7-4614-bac8-dadac6cd665c"
        }
    ]
}
```
