API Versions (V1 vs V2)
⚠️
New integrations should use API V2. API V1 is maintained for existing integrations only and will not receive new features.
AltIndex supports two API versions with separate authentication systems and base URLs.
| API V1 (Legacy) | API V2 (Current) | |
|---|---|---|
| Status | Maintenance only | Active development |
| Base URL | https://api.altindex.com | https://v2.api.altindex.com |
| Authentication | apiKey / apikey query parameter | X-API-Key header |
| API Keys | Separate from V2 | Separate from V1 |
| Who should use it | Existing V1 integrations | All new customers |
For Pro Plan Users
Pro plan API keys are issued for V2. Follow the Getting Started guide to begin integrating.
For Enterprise Users
If you have an existing V1 integration and want to migrate to V2, contact us for help aligning your endpoints and access. V1 and V2 use separate API keys, so migration requires a new key.
