Before you get started

For optimal performance, Marsello requires an exclusive API Connection. This is to ensure that your customers, orders, and products are processed in real-time as much possible.

If you have another App using your API key, please reach out to Cin7 to ask for another API Connection for Marsello.

📝 Please note: Cin7 API has an interaction limit, so if you have more than one 3rd party app using the same API connection this may cause data syncing delays.

Complete your Cin7 + Marsello Connection

After you install Marsello, you'll need to do a couple more steps to complete your Cin7 connection. You'll need to enter the following information into Marsello:

  • Your Cin7 API Username

How to find your Cin7 API details
