Stripe accepts metadata passed using API calls. To send additional data to Stripe, the QuoteTransfer::PAYMENT::ADDITIONAL_PAYMENT_DATA field is used; the field is a key-value array. When sending requests using Glue API, pass the additionalPaymentData field in the POST /checkout request.

POST https://api.your-site.com/checkout
Content-Type: application/json
Accept-Language: en-US
Authorization: Bearer 

{
    "data": {
        "type": "checkout",
        "attributes": {
            "customer": {
                ...
            },
            "idCart": "",
            "billingAddress": {  
                ...
            },
            "shippingAddress": {
                ...
            },
            "payments": [
                {
                    "paymentMethodName": "Stripe",
                    "paymentProviderName": "Stripe",
                    "additionalPaymentData": {
                         "custom-field-1": "my custom value 1",
                         "custom-field-2": "my custom value 2"
                    }
                }
            ],
            "shipment": {
                "idShipmentMethod": 
            }
        }    
    }
}

The metadata sent using the field must meet the following criteria:

ATTRIBUTE MAXIMUM VALUE
Key length 40 characters
Value length 500 characters
Key-value pairs 50 pairs
Show allHide

When you pass metadata to Stripe, it’s stored in the payment object and can be retrieved later. For example, this way you can pass an external ID to Stripe.

When a PaymentIntent is created on the Stripe side, you can see your passed additionalPaymentData in the Stripe Dashboard.
