+
+## Supported Phoenix Endpoints
+Phoenix now supports multiple deployment types. The correct endpoint depends on which version of Phoenix Cloud you are using.
+
+**Phoenix Cloud (With Spaces - New Version)**
+Use this if your Phoenix URL contains `/s/<space-name>` path.
+
+```bash
+https://app.phoenix.arize.com/s/<space-name>/v1/traces
+```
+
+**Phoenix Cloud (Legacy - Deprecated)**
+Use this only if your deployment still shows the `/legacy` pattern.
+
+```bash
+https://app.phoenix.arize.com/legacy/v1/traces
 ```
 
+**Phoenix Cloud (Without Spaces - Old Version)**
+Use this if your Phoenix Cloud URL does not contain `/s/<space-name>` or `/legacy` path.
+
+```bash
+https://app.phoenix.arize.com/v1/traces
+```
+
+**Self-Hosted Phoenix (Local Instance)**
+Use this when running Phoenix on your machine or a private server.
+
+```bash
+http://localhost:6006/v1/traces
+```
+
+Depending on which Phoenix Cloud version or deployment you are using, you should set the corresponding endpoint in `PHOENIX_COLLECTOR_HTTP_ENDPOINT` or `PHOENIX_COLLECTOR_ENDPOINT`.
