How to set up Shopify in Loomis Pay

You'll need API access in Loomis-Pay and a Shopify account to get started.

  • Loomis Pay is available as an Application in the Application store at Shopify.

  • This Application is not public and is set up on request for Shopify integration.

  • Support will send a request to your Shopify account to set up the integration.

  • For us to be able to send the request, we need your store name in Shopify.

If you are unsure of the specific store name, this is available in Shopify under: Settings– General – Store name.

  • Shopify also has the option of multiple locations. It is important that the correct Shopify location is linked to the corresponding department in LoomisvPay.

  • An overview of your store's locations in Shopify is available under: Settings– Locations. Your store's Shopify locations appear here with the name for each location.

  • A department in Loomis Pay can be linked to a Shopify location. If you need several Shopify locations linked to Loomis Pay, a department is required for each Shopify location.


Import of product registers from another system.
If your store has a Shopify online store from before, Loomis Pay can download your product register directly from Shopify into Loomis Pay.

Before the product inventory is synced from Shopify to Loomis Pay, there are a few things we need to take care of and be aware of.

SKU: If one or more products are missing SKU, a random item number will be generated for the product in Loomis Pay. The best recommended practice is to add the SKU to all products before syncing from Shopify to Loomis Pay is carried out.

Duplicate SKU: If one/more products have the same SKU, the SKU from Shopify will be used as the item number for only one of the products in the Loomis Pay. The remaining products will have one random item number generated in Loomis Pay. The best recommended practice is to conduct a review of the product registry in Shopify to make sure that there are no duplicate SKUs.

Multi Choice Variant Products: If you currently have products with multiple variant options, e.g. "T-Shirt" in different sizes and colors, this will be synchronized to Loomis Pay without any problems. Loomis Pay supports "one level" of variants, the variants will therefore be merged, and you will get one variant for all possible combinations of the product in Loomis Pay. If you want to continue creating products with multiple choices, you must continue with Shopify as your product base creation.

Shopify has several different extensions available from its App store that can generate SKUs for your products and let you know if you have products with duplicate SKUs.

Here is a link to a some possibilities you can have help you.

After the product inventory has been synced from Shopify to Loomis Pay, the product base can be switched from Shopify to Loomis Pay.


If Shopify is used as a product base, inventory counts, etc., must be carried out in Shopify.
If your store does not have a Shopify online store from before, you choose which system you want to be the product base. The recommended practice is to use Loomis Pay as the product base.

Setup with Loomis Pay as master of handling data

From the product register in Loomis Pay, you choose which products your store wants to synchronize from Loomis Pay to Shopify.

  1. Use the menu in the left side to choose menu option Products -> Products.

  2. Search for the product you want to sync from Loomis Pay to Shopify.

  3. Click on the ‘’name’’ of the product.

  4. Enable ‘’Show in online store’’ parameter and press ‘’Save’’.

  5. The product is now synced to Shopify.

When creating new products in Loomis Pay, all product data specified for the product will be synced to Shopify, and used to create the product in Shopify.


Explanation of which product values in DUEL correspond to which product values in Shopify:

• Loomis Pay Productnumber = Shopify SKU

• Loomis Pay Barcode = Shopify barcode/strekkode

• Loomis Pay Productgroup = Shopify product type

• Loomis Pay manufacturer = Shopify vendor/seller

Product values that can be changed in Shopify, after the product is synced from Loomis Pay:

Product description text: The description from Loomis Pay will be used when the product is first synced from Loomis Pay to Shopify. This can be changed in Shopify as needed to better format the text for online stores.

Product image(s): Images can be added to Shopify, and you can also change the main image for the product. Loomis Pay supports one image per product.

Product type: The product group will be used for this field when the product is synced from Loomis Pay to Shopify. The field can then be changed as needed in Shopify.

Product collections: Collections can be freely changed in Shopify.

Loomis Pay will not overwrite the above data if it is updated in Loomis Pay. The following fields must therefore be updated in Shopify, possibly also in Loomis Pay as needed.

Product data not specified in the list of MUST be changed in Loomis Pay.


Important points to remember/consider.

These actions MUST be performed in Loomis Pay, given that Loomis Pay is configured as the product base.

• Creating new products.

• Update/change of product data (certain product data values are not updated across the systems but are used when creating new products across the systems. These parameters can be changed in Shopify after the product has been synced from Loomis Pay to Shopify.

• Stock takes and goods receipt.

If one product is deleted in Shopify or Loomis Pay, the system will have problems syncing this product. It is therefore important that the product is deleted in both systems to avoid synchronization problems.

Shopify has the option to deactivate products from display in the online store if your store has a seasonal catalog, e.g. To deactivate a product in Shopify, first search for the product, click on the product, and then select Product status: "Draft".

If you only want to delete a product in Shopify and not in Loomis Pay, disable the "Show in online store" parameter on the product card in Loomis Pay, and then delete the product in Shopify.

Multi-choice can NOT be set up in Shopify if Loomis Pay is the master for the product base. If you get a new size/color/variation of an already existing product with multiple selection, this product must therefore be set up again in order for the sync between Loomis Pay and Shopify to be correct.


Setup with Shopify as master of handling data.

With Shopify as your product master, all your products from Shopify will be synced continuously to Loomis Pay.
These actions MUST be performed in Shopify, given that Shopify is configured as the product base.

• Update/change of product data.
