​
Context

Ekho requires variantConfigIds for its checkoutCart_oncreate_v2 endpoint. You must programmatically generate them based on the specific Vehicle configuration a Buyer has selected. Please follow the guide below to generate the correct variantConfigId and successfully call checkoutCart_oncreate_v2.

​
Required Items

Ekho’s internal productId for the Vehicle model.

​
Steps

  1. Collect all accessory names in the Vehicle’s configuration into an array. E.g. Red, Extra Storage, etc. These names should align with the possible accessories specified in the Vehicle onboarding sheet you sent to Ekho.

  2. Remove symbols & spaces from the accessory names and sort alphabetically.

  3. Concatenate the names in the array using '-'. This is a variantId.

  4. Concatenate the Vehicle’s productId with the variantId using '-'.

    Example: ProductID-AccessoryA-AccessoryB-AccessoryC

  5. Use the final string as a variantConfigId, as specified in the below checkoutCart_oncreate_v2 schema:

    {
    	"cancelUrl": "www.yourwebsite.com",
    	"oemId": "oem-id",
    	"oemKey": "oem-key",
    	"variantConfigIds": ["exampleProductId-variantId"],
    	"cartVehicle":
    		{
    			"productId": "exampleProductId"
    		}
    }

​
Sample Script to Produce the variantConfigId:

const productID = "exampleProductId";
const accessoryNames = ["Red", "80HP", "Extra Storage"];
const variantId = accessories
	.map((acc) => acc.accessoryName.replace(/(\s+|[^\w-])/g, ''))
	.sort()
	.join('-');
const variantConfigId = `${productId}-${variantId}`;
// variantConfigId === "exampleProductId-80HP-ExtraStorage-Red"
