API Roadmap: What’s coming next
The API Roadmap provides visibility into planned API additions, enhancements, and deprecations across ERPx releases. Align your integration planning with upcoming platform developments and avoid building on endpoints scheduled for retirement.
Key highlights:
- Planned APIs by release cycle
- Feature enhancements and breaking changes
- Timeline for new capabilities across all domains
- Early visibility to adapt your roadmap
Check the Roadmap regularly to stay aligned with platform evolution and make informed decisions about which APIs to prioritize in your integrations.

Deprecation timeline: A structured approach
APIs are deprecated with advance notice and clear timelines. The Deprecation Timeline ensures you have sufficient time to migrate integrations to supported endpoints without service interruption.
Key highlights:
- Deprecation announcements by ERPx version
- Retirement dates and support windows
- Reason for each deprecation (replaced by, consolidated, etc.)
Review the full Deprecated endpoints reference and identify integrations that require migration.

Versioning strategy: Backwards compatibility & evolution
ERPx follows a structured versioning approach that balances innovation with stability. APIs are versioned to maintain backwards compatibility while allowing the platform to evolve without breaking existing integrations.
Key highlights:
- Semantic versioning across ERPx releases
- Backwards-compatible enhancements in minor versions
- Breaking changes reserved for major versions
- Clear deprecation notices before removal
Plan your upgrade cycles around major releases and monitor deprecation schedules to ensure your integrations remain current and supported.

Documentation approach
We are committed to delivering documentation that is clear, accurate, and consistent. Each API comes with:
- Well-defined endpoints and parameters
- Example requests
- Guidance on authentication, pagination, and error handling

We will continue to evolve and enhance the developers’ experience by:
- Expanding the API catalog beyond the initial ten APIs
- Adding deeper examples and best-practice implementation guides
This is only the beginning. The portal will evolve alongside our platform, and your feedback will help shape what comes next.
