CrossEngage Product Feed API

openapi: 3.2.0
info:
  version: '1.0'
  title: Product Feed API
  description: "The Product feed API allows you to fetch, upload, edit and delete your products in real-time. It should be used together with the File Upload functionality in case more frequent updates are necessary.\nAll default attributes are described in the [Product data feed/Available properties documentation](https://documentation.crossengage.io/feeds/product).\n######\nFor test purposes, you can try the Postman collection. The collection contains all the calls needed. [![Run in Postman](https://run.pstmn.io/button.svg)](https://app.getpostman.com/run-collection/7f6c14ba49835c19dbd7)\n#### Versioning\nThe API version is defined in the header `X-XNG-ApiVersion`. To use the product API provide version **1**.\n#### Authentication\nCrossEngage uses **header authentication**. To get your Master API key, please log in to the [app](https://app.crossengage.io) and navigate to **Settings**. You will find it in the **System setup -> API keys** section in the `Master API key` value.\nThe following is an example of the format of an authentication header:\n* `X-XNG-AuthToken`: `1ab00011122c1234`\n#### Date Format\nDates and times are expressed in ISO8601 format in UTC (Coordinated Universal Time), with a special UTC designator (\\\"Z\\\") For more information please check [here](https://www.w3.org/TR/NOTE-datetime).\n#### Error Handling\nFollowing errors are possible:\n* `401 Unauthorized access is not allowed`\n* `500 Internal Server Error`\n* `502 Bad gateway`\n* `503 Service Unavailable`\n* `504 Gateway Timeout`\n\nResume or retry uploads that fail due to connection interruptions or any `5xx` errors\n\n ##### How to retry requests made to CrossEngage in case of errors:\n\n* Use an [exponential backoff](https://en.wikipedia.org/wiki/Exponential_backoff) strategy if an export request returns a 5xx server error. These errors can occur if a server is overloaded. Exponential backoff can alleviate such problems during periods of high request volume or heavy network traffic.\n* Other kinds of requests should not be handled by exponential backoff but you can still retry a number of them. When retrying these requests, limit the number of times you retry them. For example your code could limit to ten retries or less before reporting the error to our team for investigation."
