Using the Optimizely Experimentation or Optimizely Personalization REST APIs requires access to various IDs.

For example, [masking descriptive names](docId\:BgxHHXMjh1J_RuV_wiMgy) in Optimizely Web Experimentation, Optimizely Performance Edge, or Optimizely Personalization prevents you from seeing the name of a variation or campaign in the web console. Instead, the JavaScript API, console log, and network panel return a masked identifier: a string of numbers. This is great for privacy, but challenging to troubleshoot.

Based on what type of project you have, you can use the **API Names **or **API Values** tab to find the following:

- [Account ID](docId:4Md1eUtoyeflBqjUvvChj) (for the specific experiment or campaign)
- Experiment or Campaign IDs
- Variation IDs
- Audience IDs
- Page IDs
- Event IDs
- Project IDs
- Flag IDs
- Rule IDs
- Environment keys
