Adding the Opportunity type
First, you’ll need to sync the Opportunity object to Catalog. Head to the Salesforce section of the Catalog home, click the “Import another type” button, and search for Opportunity.

Setting up the Backlink
Finally, return to the Catalog homepage, select your Salesforce Account type, and click Edit. Scroll to the Attributes section and click “Add new attribute” again. This time, scroll right to the bottom of the list and you’ll see Salesforce Opportunity under the available Backlinks.
