Subke Fulfillment Service
In order for you to use our fulfillment services and logistics, the order must be automatically transferred to our weclapp Fulfillment Center via an interface. We store your goods in our warehouse and take over inventory management after the connection. The software updates the stock and the status of the delivery in weclapp in real time. The desired shipping method is also stored.
It is important that your products have a name and a unique SKU or GTIN so that the products can be clearly identified during order picking.
It is also possible to transfer product bundles, batches or serial numbers.
Prerequisites
Active Weclapp account.
Access to JTL-FFN. As a customer, you will receive an invitation link from us for access to fulfillment.jtl-software.com.
API access data for ffn-connect. As a customer, you will receive an invitation link from us for access to ffn-connect.de.
Your JTL-FFN account
You will receive a free JTL-FFN account from us. You create this with the invitation link we send you and then follow the instructions.
You will later see the transferred products from your weclapp account in the dashboard.
You can create a goods delivery in the menu under “My processes” -> “Inbound deliveries” and specify the products with the delivery quantity.
When the goods are delivered to us, the items are scanned and you can see immediately in JTL-FFN whether they match the specified delivery quantity.
If orders are transferred, you will see them under “My processes” -> “Orders” with the current status.

Setting up the connection
You will also receive a free FFN-Connect account from us. We will also send you an invitation link for this. You can then log in there with the same access data from JTL-FFN. You then assign your own password.
Access to ffn-connect:
Visit the ffn-connect.de website and register.
Go to “My connection” in the menu on the right.
Click on the “Start connection” button at the top right.
Select the weclapp software in the center.
The connection is given a name (please use your company name).
Insert your weclapp URL. It ends with weclapp.com.
Insert the API token from weclapp. You must create this in weclapp beforehand (see below).
Click on “continue”, the connection to weclapp and our JTL Wawi will be established.

Generate Weclapp API key:
- Log in to Weclapp and go to the API settings.
- Activate the API if you have not already done so.

How returns are managed
In the ffn-connect dashboard, you can call up returns that have been received by us but have perhaps not yet been announced by the customer. You can also manually create a return in the ffn-connect dashboard, which is then transferred to our Fulfillment Center.
We can also use ffn-connect to retrieve the returns from weclapp that you have created there.
Subke IT Support
Of course, you will receive support from our IT support team if you have any questions about the connection. This standard connection for weclapp is free of one-off setup costs and includes our monthly service fee.
Test the connection
Once set up, we will test the connection with you to ensure that the data is synchronized correctly.
To do this, we create a test order in Weclapp and check whether it is displayed in JTL-FFN.
