Make.com and High Level automations expert

Here's a job post ready to paste into Upwork: Title: Make.com Fix — Expose Nested Array from GoHighLevel API (Quick Job) Description: I have an existing Make.com scenario that's 90% built and working — I need help with one specific blocker. The flow: GHL webhook → HTTP call to GHL's /messages API → Anthropic Claude API classifies the conversation as legit or flagged → Router → sends either a confirmation SMS or logs to Google Sheets. The problem: GHL's /messages endpoint returns the full conversation transcript as a nested array (data.messages.messages[]). Make's variable picker won't expose this nested array, so I can't aggregate the individual message bodies into a single text block to pass into the Claude step. As a result, Claude receives an empty conversation and flags everything. What I need: Add the correct module(s) — likely an Iterator and/or Parse JSON — so the full conversation reaches the AI step as clean text. Everything else in the scenario already works (auth, API calls, routing, SMS, Sheets logging are all functioning).
