Create MD5 Hashes for Webhook Verification

🧩 Problem

Some integrations expect MD5 signatures, but low-code tools lack hashing. 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

Legacy APIs rely on MD5 HMAC-style checks or hash comparisons. 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: Hash MD5 (API Endpoint)

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

Endpoint

POST https://api.postthatgetthis.com/hash/md5

Example Input

{ "data": "payload-to-sign" }

Example Output

{ "hash": "4c9a...md5" }

📦 What This Solves
