Flatten Webhook Payloads for Filters and Routers

🧩 Problem

Webhook payloads are deeply nested, making filters and paths brittle. 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

APIs favor nested objects; automation filters expect shallow keys. 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 Zapier, Make.com, n8n, Retool, Airtable.

Endpoint

POST https://api.postthatgetthis.com/json/flatten

Example Input

{ "order": { "id": 9, "customer": { "name": "Nia" } } }

Example Output

{ "order.id": 9, "order.customer.name": "Nia" }
