Genesys Cloud - Developer Community

We recently used Genesys Functions in Scripts to simplify an external record creation workflow and make error handling easier for agents.

The main reason for moving to a Function was that standard script data actions can be harder to troubleshoot when something fails mid-flow. By using a Function, we were able to centralize the logic and return a cleaner result back to the script.

What the Function handles:

• authentication
• person lookup
• record creation
• record detail lookup
• record assignment
• record URL generation

Why this helped:

• reduced script complexity
• kept the main logic in one place
• returned cleaner success and failure messages to the agent
• made it easier to show only the final outcome in the script, such as record number and record URL

One important issue we ran into:
When calling the Function from the script, the request body initially failed with:
“Processing the Request Body Template resulted in invalid JSON”

The fix was to escape all string inputs in the request body template.

Working example:

{
  "idValue": "$esc.jsonString(${input.idValue})",
  "recordType": "$esc.jsonString(${input.recordType})",
  "summaryText": "$esc.jsonString(${input.summaryText})",
  "detailText": "$esc.jsonString(${input.detailText})",
  "ownerName": "$esc.jsonString(${input.ownerName})"
}

This was especially important for multiline notes, URLs, and other text fields passed from the script.

We kept the response simple by using:

{
  "translationMap": {},
  "translationMapDefaults": {},
  "successTemplate": "${rawResult}"
}

A few practical lessons learned:

• test the Function directly first to confirm the code works
• if direct Function testing works but the script call fails, check the request body template next
• escape all string inputs if the Function is being called with text from the script
• keep agent-facing responses simple, for example:
  • success: record number and record URL
  • failure: a clean manual fallback message

This approach worked well for both:

• a template-based record creation flow
• a non-template record creation flow

If anyone else is using Functions in Scripts for external integrations, especially where multiline text is passed from the script, escaping the request body inputs is definitely worth checking early.
