This article provides guidance for when you see a "No Matching API Key" error when trying to launch the designer over your application.
Product area: Guides > Designer (web)
Issue
Typically, the error "No Matching API Key" is displayed when Pendo isn't being initialized properly on your application. It indicates that the initialize function isn't being called, or that a field within the function isn't being populated correctly. For a reference of initialization functions, see the developer documentation.
Diagnosis
Confirm that Pendo isn't initializing on your page.
After clearing your cache and re-launching the designer, you need to validate your Pendo install.
1. Right-click on your website and select Inspect from the dropdown menu.
2. Paste pendo.validateInstall() into the Browser Developer Console.
3. Select Enter to return metadata.
If you receive the following error message, Pendo isn't initialized on your page.
Solution
Update your Pendo snippet to include error handling using the initialize() function in your code, which allows Pendo to initialize completely.
For more information about updating the Pendo Snippet, see Developer's guide to installing Pendo.
