Sometimes events on Salesforce need to be handled by an external system due to the scale or type of process being executed. Consider the use case of a user in Salesforce needing to get pricing for an order they are building in Salesforce while on the phone with a customer.
The pricing logic already exists in a third-party system. Instead of recreating this logic in Salesforce, it will be leveraged by making a request of the third-party system. The response, in this case the pricing, will be returned and stored back in Salesforce.
What is the optimal solution?
- A Visualforce page that can make a real-time Apex callout to display and save the pricing back in Salesforce
- An Apex trigger that upon saving the Order will make a real-time Apex callout, saving the pricing back in Salesforce
- A Process Builder process and Outbound Message to fetch the pricing upon save and store the pricing in Salesforce
- An ETL tool to process batches of newly saved Orders every few minutes to store the pricing back in Salesforce
