Deprecation announcement: Selected API endpoints to be retired on March 16, 2026
Ensuring a secure, efficient, and modernized API portfolio
To improve platform performance and focus investment on high value APIs, we are deprecating and retiring selected low usage endpoints. These endpoints will be permanently removed on March 16, 2026. This change is aimed at ensuring Enphase Energy’s API portfolio remains secure, efficient, and aligned with our long-term product roadmap. We understand that API changes require planning, and we are committed to providing clear guidance and support throughout this transition.
🗓️ Deprecation timeline
📋 Endpoints affected
The following endpoints are scheduled for deprecation:
- PUT /api/v4/systems/{system_id}/meters/{serial_number}
- PUT /api/v4/partner/systems/{system_id}/arrays
- GET /api/v4/partner/systems/{system_id}/arrays/{array_id}
- PUT /api/v4/partner/systems/{system_id}/arrays/{array_id}
- DELETE /api/v4/partner/systems/{system_id}/arrays/{array_id}
- PUT /api/v4/systems/config/{system_id}/tariff
- GET /api/v4/companies/{company_id}/users/{user_id}
- GET /api/v4/activations/{activation_id}/estimate
- PUT /api/v4/users/{user_id}
These endpoints have shown minimal or no active traffic over the past 12 months. If you believe your application relies on any of these endpoints, please contact our team as soon as possible so we can evaluate your situation before retirement.
❗ What you need to do
If your applications are unexpectedly using any of the listed endpoints:
- Validate whether they are still required for your operations.
- Remove or disable any references to these legacy endpoints.
- Update your integrations before March 15, 2026.
Note: Post-retirement, calls to these endpoints will return an HTTP 401 error.
❓ Why we're making this change
Retiring low usage and legacy endpoints enables us to:
- Improve platform reliability and security
- Reduce unnecessary operational overhead
- Simplify the developer experience
- Focus our efforts on high value, modernized APIs
These changes help ensure the efficiency, sustainability, and convenience of the platform.
