Timeline of order flow

Step 0. Create a Customer via Slope API

Create a customerthat the order will be attached to.

POST https://api.slope.so/v3/customers HTTP/1.1

{
  "email": "[email protected]",
  "externalId": "<your_customer_unique_identifier>",
  "phone": "+14151234567",
  "businessName": "Stark Industries, Inc",
  "address": {
    "line1": "200 Park Avenue",
    "city": "New York",
    "state": "NY",
    "postalCode": "10166",
    "country": "US"
  }
}

Step 1. Create an Order via Slope API

Create an order for whatever amount needs to be paid or financed.

POST https://api.slope.so/v3/orders HTTP/1.1

{
     "total": 1000,
     "currency": "USD",
  	 "externalId": "<your_order_unique_identifier>",
     "items": [
         {
             "sku": "CL-SOCKS-2",
             "unitPrice": 500,
             "quantity": 2
         }
     ],
     "customerId": "<slope_customer_id>"
 }

Step 2. Generate an order intent via Slope API

Generate an order intent token, that allows the Slope widget to be completed by the customer.

📘

Order intent tokens expire

Order intent tokens expire after four hours. We recommend you generate the order intent token right before displaying the Slope widget.

If an expired secret is passed to the Slope Popup the onFailure callback with a ORDER_INTENT_EXPIRED secret. You must generate a new one your server and re-initialize the popup.

On your server:

POST http://api.slope.so/v3/orders/{{orderId}}/intent HTTP/1.1

Step 3. Open the Slope widget for the Customer to complete

Using the {{ORDER_INTENT_SECRET}} from Step 2, initialize Slope's widget. On the front-end:

<!-- embed our library -->
<script src="https://checkout.slope.so/slope.min.js"></script>


<!-- initialize the widget and open it -->
<script type="text/javascript">
 window.initializeSlope({
     intentSecret: ORDER_INTENT_SECRET,
 })
</script>
<button onclick="window.Slope.open()">Pay with Slope</button>

Full reference here. The customer will select payment terms, a payment method, and accept any Terms and Conditions that are necessary - the order will be in the open state after the Customer has completed the widget.

Step 4. Finalize the order via Slope API

Finalize the order once you have confirmed the order is ready.

POST https://api.slope.so/v3/orders/{{ORDER_ID}}/finalize HTTP/1.1
