Normalize Base64 Strings from APIs

🧩 Problem

Base64 strings include whitespace or missing padding, breaking decodes. 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 and AI tools wrap base64 in markdown or remove padding characters. 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.
