Products Import from Sunsky-online Api in my Onlineshop (Shopware)

My vendor offers an API interface that allows you to import the products. Unfortunately I do not know how it works or how to program it. I would like to be able to import all articles and categories with pictures and text. Who knows that? It should be best to upgrade every day for price or item changes or stock.

Common Parameters: key: The api key you got from SUNSKY Open API Platform. signature: The signature for the parameters, it is generated with the parameter values and the secret you got from SUNSKY Open API Platform. Attention: The parameters should be sorted by the name before the signature generation. 3. Result Format The return value is formatted in JSON. (a) Successful Result Example: { result: "success", data: [{"id":1032,"code":"003","gmtCreated":"01/31/2013 00:00","name":"N Style Phone","parentId":408,"status":1}] } (b) Failed Result Example: { result: "error", messages: [ "The record you visiting does NOT exist." ] } 4. Call Frequency Control SUNSKY will limit the API call frequency in case the mass calls overwhelm the servers. Please refer this to get the frequency control info: [login to view URL]![login to view URL] Attention: All the parameters and return values are case sensitive. Interface 1: Get children of the category specified in the parameters (a) URL: /openapi/category![login to view URL] (b) Parameters: If you don't pass any parameter, this API will retur all of the categories. You can specify the parameters below to filter the categories you want to fetch: * parentId: The ID of the category, which you want to get its direct child categories, optional; * gmtModifiedStart: To fetch the categories ever changed since 'gmtModifiedStart', in the format of MM/dd/yyyy HH:mm:ss(i.e. 10/31/2013 01:23:20), optional; (c) Result: Summary: * If you don't pass the parentId parameter, then an array of the all categories is returned; * If you specify '0' for the parentId, then an array of the top categories is returned; * If you specify other number for the parentId, then an array of the direct child categories is returned; * If you specify a date for the gmtModifiedStart, then an array of the categories ever changed since 'gmtModifiedStart' is returned; Fields: * id: The unique ID of the category; * code: The code of the category. The children of the category are sorted by code; * name: The full name of the category; * shortName: The short name of the category, could be empty; * hsCode: The HS code for the products in the category, could be empty. If the HS code is empty, please check the HS code of the parent category; * status: The status of the category. See Appendix A; * parentId The ID of the parent category; * gmtModified: The change time, in format of MM/dd/yyyy HH:mm:ss (i.e. 10/31/2013 01:23:20); Hint: How to get the changed categories? (1) Before calling the getChildren API, load the previously saved time T0 from db/file; (2) Call the getChildren API with gmtModifiedStart=T0, it'll return the categories that ever changed since T0; (3) Update your local db with the category data returned by the getChildren API; (4) Update T0 to the max gmtModified among the catetories returned by the getChildren API, then save T0 to db/file; (5) Increase the page number and repeat step 2~4 until the getChildren API returns no data;
