Migration Notes

Upgrading to Latest

No breaking changes in the current version. All existing integrations should continue to work.

Response Format Changes

The API now consistently returns:

• Amounts as strings: "1000.00" instead of 1000
• Success flag: "success": true on all successful responses
• CamelCase field names in responses

These changes are backward-compatible. If you're parsing amounts as numbers, the string format will still work with most JSON parsers.

Deprecation Policy

• Deprecated features are announced at least 3 months before removal
• Deprecated endpoints continue to work but may not receive new features
• Breaking changes are only introduced in major version updates (v2, v3, etc.)
