Decode Base64 to Images for Webhooks

🧩 Problem

APIs send images as base64 strings, but downstream steps need image files or URLs. 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

Base64 avoids multipart uploads; automation still needs binary assets. 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.
