Connect the correct shop to Sello and check the data flow before expanding marketplace sales.
The connection can be used with Abicart Go, Plus and Pro. You need a Sello account and agreements for the marketplaces you will use. Abicart access does not mean that Sello services or marketplace fees are included.
Prepare the shop and data ownership
Check the shop ID at the top of Abicart admin. Decide which system owns products, prices and stock, and how incoming orders will be handled. Two connections writing the same stock field can cause incorrect quantities and overselling.
Create a dedicated API key in Abicart
Open Settings → Apps → Abicart API.
Open the API-key section. In older admin versions, the card itself may be named API keys rather than Abicart API. Add a key with a clear name, such as Sello. Select Active and save or add it as shown in the form.
Copy the key into Sello’s connection field. Do not share it in email, screenshots or public text.
Connect and verify in Sello
Open Sello’s webshop connection settings and choose Abicart. Enter the correct shop ID and dedicated API key. Labels and steps can change in Sello; use its current Abicart connection workflow.
Check a limited product selection with unique product numbers, prices, currency and stock in both systems. Also check how an order returns and updates stock before using the workflow broadly. An accepted key proves access, rather than correct synchronization of every field.
Troubleshoot and retire safely
For connection errors, check the shop ID, active key and correct Sello connection. For incorrect data, check field ownership, product numbers and synchronization settings before starting a bulk transfer. When retiring the connection, revoke only the dedicated key after checking that other integrations do not use it.
