I have signed up for Seller Fulfilled Prime (SFP) program and would like to start using it in Linnworks.


Step 1 - Add the 'Amazon - Buy Shipping' integration to Linnworks, which is the dedicated Shipping integration for printing SFP labels.

Proceed to > Shipping > Integrations > Add new > Amazon - Buy Shipping > Integrate:

Important! Please make sure to accept Terms and Conditions for all carriers via the following links:

Amazon UK:

Amazon US:

Step 2 - After filling out all of the details, proceed to the Services tab and select the services you wish to use for Prime orders from the drop-down menu and click Add:

NB! You cannot have the same Linnworks Postal Service linked with several shipping integrations, so all Amazon Buy Shipping services will need to be created as new services. By choosing the service from the drop-down menu in the integration and saving changes you will create a new postal service automatically. 


- If you wish to use DPD services for SFP, please make sure to follow all the steps described in this article as well.

- You cannot use your direct Royal Mail Tracked integration to print prime labels. Royal Mail Tracked services would need to be added to the Amazon Buy Shipping integration.

Step 3 - Automatically assign Next Day and Standard prime services to your SFP orders.

All Amazon orders that are required to be shipped Next Day will have 2 order identifiers assigned to them by the system automatically: 

  • Amazon prime delivery


  • Amazon Premium Order


All Standard prime orders will however only have 1 order identifier assigned to them:

  • Amazon prime delivery


Using the order identifiers you would need to set up Rules Engine to allocate services automatically:

1. Create a new rule via > Orders > Rules Engine > +Add new rule

2. The first set of conditions will need to check the order Source and/or SubSource and whether an order has both order identifiers assigned to it (Amazon prime delivery and Amazon Premium order). 

Here is an example of the condition that you will need to create for a Next Day Prime order:

If all of the above conditions will be met, the Action would need to assign the Next Day Prime service that you have added to the integration:

3. After this click on +Add New button and add the next set of conditions to the same rule. This time you will need to check the Source and/or SubSource and whether an order has just the one order identifier (Amazon prime delivery) and does not have the Amazon Premium Order one:

Action for this would be to assign the Standard Prime service.

Here is an example of how the prime rule will look like in the end:


While the Amazon Premium Order identifier will only be visible in the new Open Orders (BETA) screen, the rule will still run correctly on the order, as all of the information is stored in the system.

Step 4 - Above set up will ensure that Prime orders will have the correct service allocated to them prior to printing. In order to make sure that the shipping label will be printed, you will also need to have correct weight and dimensions assigned to the order, as otherwise an error will be returned from Amazon.

The most accurate way to assign correct weights and dimensions would be to assign them to Inventory items using Inventory import.

Possible errors

The most common error when printing Amazon - Buy Shipping labels is an error indicating that no services are available for the consignment. This error is returned directly from Amazon, and the following article will allow you to troubleshoot the problem and resolve it: Shipping - Amazon Buy Shipping error GetEligibleShippingService: Error

Submitting end of day Manifest for Royal Mail

Amazon Buy Shipping API does not support manifesting from Linnworks. The manifest can still be filed in Linnworks internally for your own reference and to clear the Shipping manifest screen. Please note that this means that no details will be sent to the shipping vendor, and you will not be able to print the manifest documents from Linnworks. Therefore you will need to file and print all manifest documents via Seller Central directly.
