Who is this for?
This documentation is for developers creating their own integration with Feedback's API. If you are doing a standard integration, there's a really easy Javascript integration that you should know about before you go to the effort of building your own integration.
Authentication
API calls generally need to be authenticated. Generate an API Key at https://feedback.pendo.io/app/#/vendor/settings?section=integrate. This key should then be added to every request as a request header named 'auth-token' (preferred), or as a query parameter named 'auth-token'.
Endpoint
API endpoint is https://api.feedback.eu.pendo.io / https://api.feedback.us.pendo.io depending where your datacenter is located.
Notes
API endpoints are being added to this documentation as needed by customers. If you don't see an endpoint you need please contact support and if it exists we'll publish the docs here. The 'try it out' feature on this documentation page will probably be blocked by your browser because the Access-Control-Allow-Origin header has its value set by the Feedback server depending on your hostname.
Generating client code
This documentation is automatically generated from an OpenAPI spec available here. You can use Swagger to auto-generate API client code in many languages using the Swagger Editor
