If you are using an external system like a POS or an Inventory Management system then Presto supports integration with that system. A lot of integrations are already available with Presto. Please check with your Presto representative about the availability of support for your system. Further Presto exposes standard HTTP Push APIs, which can be consumed by your system.


For the scope of this article we will refer to all such POS / Inventory Management software as the "external system".


The most common goal of such an integration is to push the incoming Orders into the external system. Most often this would require referring to the items in the order using their unique ids in the external system. Presto supports establishing this link through a field called "Reference Id" on each of the items in the catalog. Here are the steps to establish that link : 


  1. Login to the admin console
  2. Click on the "Catalogs" button. This gives you the list of catalogs you have created. It could be one or many.
  3. Click on the appropriate catalog to see the categories and/or items you have in that catalog.
  4. Click through the categories to get to the item you want to link.
  5. Click on the "Edit" button for the relevant item. The item edit screen will show up.
  6. Scroll down to find the "Reference Id" field
  7. Enter the unique id of this item in the external system in the "Reference Id" field.
  8. Click on the "Update" button to save the details.


After this Presto will pass along the specified "Reference Id" in all the communication with the external system.
