This topic describes how to:
  • Find IDs needed to access the Optimizely Experimentation APIs
  • Identify an audience, campaign, or page by its ID when descriptive names are masked (Web and Performance Edge)
  • Troubleshoot using the JavaScript API, console log, or network panel

It is sometimes useful to know various experiment or campaign IDs for troubleshooting or when using an Optimizely API. 

For example, masking descriptive names in Optimizely Web or Performance Edge prevents seeing the name of a variation or campaign in the 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 for troubleshooting.

Additionally, you will need certain IDs when using the Optimizely APIs. Refer to the API Reference documentation for more information. 

Use the API Names panel to find: 

  • Account ID (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

For information about Account IDs, refer to the documentation on Accessing the Account ID and Multi-account login in Optimizely.
