Mock sample for your project: Swagger API2Cart

The Browse API has the following resources: itemsummary: Lets shoppers search for specific items by keyword, GTIN, category, charity, product, or item aspects and refine the results by using filters, such as aspects, compatibility, and fields values. (Experimental) searchbyimage: Lets shoppers search for specific items by image. You can refine the results by using URI parameters and filters. item: Lets you retrieve the details of a specific item or all the items in an item group, which is an item with variations such as color and size and check if a product is compatible with the specified item, such as if a specific car is compatible with a specific part. Provides a bridge between the eBay legacy APIs, such as Finding, and the RESTful APIs, which use different formats for the item IDs. (Experimental) shoppingcart: Provides the ability for eBay members to see the contents of their eBay cart, and add, remove, and change the quantity of items in their eBay cart. Note: This resource is not available in the eBay API Explorer. The itemsummary, searchbyimage, and item resource calls require an Application access token. The shoppingcart resource calls require a User access token.

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
