Custom Delivery Adapter
If you want total control of the provided delivery methods, you can build and host an own adapter that will empower Walley Checkout with delivery methods. This allows you to separate the items in the cart in different shipments, set specific pickup/delivery dates, add options to each delivery etc.
How to get started 🚀
- Contact Walley Merchant Services for help with setup in our test environment and for questions regarding integration with the Delivery Module.
- Build a delivery adapter (api) with an endpoint that Walley Checkout will do a GET request towards to get the delivery methods that should respond according to the response below. Use basic auth as authentication.
- Provide Walley Merchant Services with the adapter endpoint url, basic auth credentials as well as what fallback strategy to use.
How delivery methods are fetched
Walley Checkout fetches the list of available delivery methods every time the customer changes any information that might lead to a change in available delivery methods, e.g. the customer changes delivery address or updates the cart.
Default Request Query Parameters
When the Checkout sends the GET request to the delivery adapter, it will include some default query parameters.
| Parameter | Explanation |
|---|---|
| storeId | The storeId for the checkout session |
| privateId | The checkout's private id which can be used to fetch information about the checkout |
| storeType | CustomerType for the checkout session, b2b or b2c |
| currency | Currency used for the checkout session |
| language | The display language used for the checkout session. Supported language are: sv, no, fi, da, en |
| cartPrice | The total price for cart |
| cartWeight | The total weight for the cart, sum of all the article's weights sent in set cart request |
| The customer's email address | |
| address | The address for the customer's current delivery address |
| postalCode | The postal code for the customer's current delivery address |
| countryCode | The country code for the customer's current delivery address |
When requesting for available shipping methods, apart from all the parameters above, you can set custom parameters that is related to articles in the cart.
This is done by adding shippingProperties to the cart object in either Initialize Checkout
or Update Cart
as a JSON object that will be be added in the request query parameters automatically the following way:
{
"items": [
{
"id": "2",
"description": "A bulky product",
"unitPrice": 100,
"unitWeight": 2,
"quantity": 1,
"vat": 20,
"requiresElectronicId": true,
"sku": "a unique alphanumeric code for article identification"
}
],
"shippingProperties": {
"height": 10,
"width": 20,
"isBulky": true
}
}
The following scenario would result in the following query parameters when the GET-request is sent to your adapter:
https://{UriToAdapter}?storeId={storeId}&....&address={address}&height=10&width=20&isBulky=true
Please note
Since the privateId is sent in the query, it is possible to Acquire Checkout Information to get more information. Consider that this will add some time for your customer in the checkout.

Fallback strategy
If, for any reasons, Walley Checkout does not receive any delivery methods from your adapter, there is a setting that you will set up in advance that will decide if the purchase should be stopped or not
- true: We will show an error and stop the purchase if we cannot fetch at least one valid delivery method
- false: We will allow the customer to complete the purchase, saying that a delivery method will be selected automatically without cost
Error message response
If the GET-request is received successfully but no delivery methods can be returned, you can choose to return a non-2xx response with the following properties to inform the customer what is wrong and what action to take. This requires the fallback strategy to be set to true.

| message | No | The message with a more descriptive text why no delivery methods was found, and how the customer should proceed. Truncated to max 512 chars. |
A default message will be shown if not overridden with title and message from the response. Both title and message must be specified in the response to be used.

The 200-response from the example above will render the following delivery methods to the customer.
Fetch the customer's selected delivery method
When Acquiring Checkout Information, a data.shipping object will be available that will reflect the customer's current delivery selection.
If this value is null, there are no selection at that current state of the checkout.
After purchase the selections are included in the order.
- Scenario 1. Successfully fetched delivery methods
- Scenario 2. Failed to fetch delivery methods, with fallback strategy to allow purchase anyway
