Use Base64 in API Debugging

When request or response payloads include Base64 fields, this workflow helps you quickly verify encoding direction, readability, and transport safety.

Suitable Input Types

  • Raw Base64 fields copied from API request or response payloads
  • Plain text snippets that must be encoded before sending
  • JSON payload fragments where one field contains encoded content

Step-by-Step Workflow

  1. Open Text workspace and paste the target field from your payload.
  2. Switch mode based on direction: Base64 → Text for inspection, Text → Base64 for rebuilding.
  3. Copy normalized output back into your API request, test script, or docs.

Example Walkthrough

Base64 to text

Input: VGVzdCBkYXRhIGZvciBCYXNlNjQ=

Action: Use Base64 → Text in the Text workspace.

Output: Test data for Base64

Common Issues in This Scenario

Copied value contains hidden spaces or line breaks

Trim accidental whitespace before decoding. Wrapped lines from logs often break decoding.

You encoded an already encoded field

If output looks unreadable after decoding once, verify whether source data was double-encoded in upstream logic.

Padding mismatch between systems

Some systems omit trailing "=". Check compatibility expectations before comparing values.
