Answer: B

Explanation:

An AI Specialist wants to include data from the response of an external service invocation (REST API callout) into a prompt template. The goal is to incorporate dynamic data retrieved from an external API into the AI-generated content.

Solution:

Use External Service Record Merge Fields

External Service Integration:

Definition: External Services in Salesforce allow the integration of external REST APIs into Salesforce without custom code.

Registration: The external service must be registered in Salesforce, defining the API’s schema and methods.

External Service Record Merge Fields:

Purpose: Enables the inclusion of data from external service responses directly into prompt templates using merge fields.

Functionality:

Dynamic Data Inclusion: Allows prompt templates to access and use data returned from REST API callouts.

Merge Fields Syntax: Use merge fields in the prompt template to reference specific data points from the API response.

Implementation Steps:

Register the External Service:

Use External Services to register the REST API in Salesforce. Define the API’s schema, including methods and data structures. Create a Named Credential:

Configure authentication and endpoint details for the external API.

Use External Service in Flow:

Build a Flow that invokes the external service and captures the response. Ensure the flow outputs the necessary data for use in the prompt template.

Configure the Prompt Template:

Use External Service Record merge fields in the prompt template to reference data from the flow’s output.

Syntax Example: {{flowOutputVariable.fieldName}}

Why Other Options are Less Suitable:

Option A (Convert the JSON to an XML merge field):

Irrelevance: Converting JSON to XML merge fields is unnecessary and complicates the process. Unsupported Method: Salesforce prompt templates do not support direct inclusion of XML merge fields from JSON conversion.

Option C (Use “Add Prompt Instructions” flow element):

Purpose of Add Prompt Instructions:

Allows adding instructions to the prompt within a flow but does not facilitate including external data.

Limitation: Does not directly help in incorporating external service responses into the prompt

template.

Reference: Salesforce AI Specialist Documentation – Integrating External Services with Prompt Templates:

Explains how to use External Services and merge fields in prompt templates.

Salesforce Help – Using Merge Fields with External Data:

Provides guidance on referencing external data in templates using merge fields.

Conclusion:

By using External Service Record merge fields, the AI Specialist can effectively include data from external REST API responses into prompt templates, ensuring that the AI-generated content is enriched with up-to-date and relevant external data.
