Optimize your Facebook Ads for customer interactions that happen outside of the browser.
Firstparty will query your Salesforce instance for Opportunities (or anything else), create an Event for every row of data returned by your query, and send each Event to Facebook Ads so you can configure a Facebook Ads Campaign to optimize for that specific conversion.
This Recipe will guide you through connecting to Salesforce, connecting to Facebook Ads, and configuring a Rule that will send those Events to Facebook Ads as a conversion event.
Firstparty will guide you step by step.
