登錄api.sap.com, 根據(jù)關(guān)鍵字SuccessFactors找到對應(yīng)的API目錄：
找到foundation/Platform級別的API，進入之后，
選擇User Management:
點擊Logon，以使用API控制臺自帶的控制功能：
點擊Try Out, 就可以像使用postman一樣，使用這個API控制臺自帶的測試功能了：
$filter string里可以測試這個OData API的filter操作：
從測試結(jié)果可以發(fā)現(xiàn)，firstName為Sami的user，在這個sandbox系統(tǒng)里的user ID為50004：
點擊Show API Key，拿到一個API key，這樣就能在該API控制臺以外的地方調(diào)用API.
點擊Code Snipet，可以把自動生成的API調(diào)用代碼復制下來，直接粘貼到應(yīng)用里使用。
點擊Curl，獲得使用工具curl進行測試的命令行：
curl --request GET --url "https://sandbox.api.sap.com/successfactors/odata/v2/User" --header "APIKey: e9ZLBOfexchhHN" --header "Accept: application/json" --header "Content-Type: application/json"
curl --request GET --url "https://sandbox.api.sap.com/successfactors/odata/v2/User" --header "APIKey: e9ZLBOkMUexchhHN" --header "Accept: application/json" --header "Content-Type: application/json"

得到的結(jié)果:
也可以通過select操作，讓API只返回firstName和lastName兩個字段的值：
curl --request GET --url "https://sandbox.api.sap.com/successfactors/odata/v2/
User,UserPermissions/User?%24top-5&%24select=firstName%2ClastName" --header 'APIKey: e9ZLBOXsAfkMUexchhHN' --header 'Accept: application/ison' --header "Content-Type: application/ison"
curl --request GET --url "https://sandbox.api.sap.com/successfactors/odata/v2/User,UserPermissions/User?%24top-5&%24select=firstName%2ClastName" --header "APIKey: e9ZibykWXsAfkMUexchhHN" --header "Accept: application/json" --header "Content-Type: application/json"
