Create a transaction

Next, a transaction can be created using the same identifiers. 
POST /transactions

{
    "amount": 1299,
    "currency": "AUD",
    "country": "AU",
    "intent": "capture",
    "buyer_external_identifier": "user-edp",
    "shipping_details_id": "01da1af5-66fa-4439-a520-e166fecebc43",
    "payment_method": {
        "method": "wpay-everydaypay",
        "country": "AU",
        "currency": "AUD",
        "redirect_url": "https://example.com"
    },
     "connection_options": {
        "wpay-everydaypay": {
            "rewardsAccessToken": "2sSVapXfQixwW30huM6JggmcxWlw",
            "customerId": "21b93354043ccda7b45c5778f9738bde2e97496c3ab5d7586bdee25450f9bd2b",
            "deviceId": "4e95fcad-e81c-4018-85c1-e2d2c46ee6de"
        }
    }
}
Please note that the intent needs to be capture and that a buyer needs to be present with both a billing address and a shipping address.For the addresses, the line1, city, country, postal_code and state fields need to be set.
This will return a response with an approval URL. 
{
    "type": "transaction",
    "id": "dfa9e5b0-7b50-42dc-8420-95d34dd59d24",
    "method": "givingblock",
    "merchant_account_id": "default",
    "status": "buyer_approval_pending",
    "amount": 1299,
    "currency": "AUD",
    "country": "AU",
    "intent": "capture",
    "payment_method": {
        "type": "payment-method",
        "method": "wpay-everydaypay",
        "mode": "redirect",
        "approval_url": "https://tgb-preprod.com/?charityID=1189132672&version=2&donationDataId=54e15be4-2576-421d-a938-bf93e5a57743&apiUserUuid=a658a418-d116-4e72-9014-f2f37a3976ab",
        ...
    },
    ...
}
The user can then be redirected to this URL to complete the payment. After completion, the status of the transaction will be either capture_succeeded or authorization_failed/authorization_declined.
