Flatten JSON for Slack Digest Messages

🧩 Problem

Slack messages with nested JSON are unreadable. When malformed or unstructured data hits routers, filters, or API connectors, entire automations halt or silently drop records. Teams end up retrying runs, hand-editing payloads, and explaining delays to customers.

💡 Why This Happens

API responses are nested; Slack prefers key:value lines. Most automation platforms assume well-formed payloads and do minimal validation. AI models, third-party APIs, and changing vendor schemas drift over time, mixing encodings, formats, and unexpected fields that downstream steps cannot tolerate.

🚀 The Fix: JSON Flatten (API Endpoint)

Use this endpoint to solve the problem reliably inside Slack, Zapier, Make.com, n8n.

Example Input

{ "event": { "type": "order", "meta": { "region": "us-east" } } }

Example Output

{ "event.type": "order", "event.meta.region": "us-east" }
