What capability should be considered to synchronize data changes in Salesforce to a 3rd party with a JSON-based API?

The choice of utilizing an Apex class to perform the REST callout asynchronously is a sound approach for synchronizing data changes from Salesforce to a third-party application with a JSON-based API. This method is effective because it allows for greater control over the data being sent while ensuring that the process does not block other operations within Salesforce.

Asynchronous processing is crucial when dealing with external API calls, especially when responses can vary in terms of time. By handling the callout asynchronously, Salesforce can process the data changes independently of the main transaction, thereby enhancing performance and user experience. This means that if there are several data changes happening in Salesforce, the integration will not slow down or disrupt other processes.

Moreover, using an Apex class for the callout provides the flexibility to manipulate the data before it is sent, including building the JSON payload according to the requirements of the third-party API. It can also handle any necessary error management and logging which is essential when synchronizing data with external systems.

In contrast, using outbound messages, while automated, relies on the older SOAP format and does not offer the same level of flexibility or customization as a programmatic approach via Apex. Lightning Connect is designed for real-time data access and is better suited for scenarios where the data is
