Google Custom Search JSON API - json

Question

I'm playing with Google Custom Search API with Custom Search Engine (CSE) via JSON API. I successfully obtained search result, but I'm clueless about how to obtain the nextPageToken.
https://www.googleapis.com/customsearch/v1?key=MY_API_KEY&cx=MY_SEARCH_ENGINE_ID&q=Testing
The JSON response is as follow:
{
"kind": "customsearch#search",
"url": {
"type": "application/json",
"template": "https://www.googleapis.com/customsearch/v1?q={searchTerms}&num={count?}&start={startIndex?}&lr={language?}&safe={safe?}&cx={cx?}&cref={cref?}&sort={sort?}&filter={filter?}&gl={gl?}&cr={cr?}&googlehost={googleHost?}&c2coff={disableCnTwTranslation?}&hq={hq?}&hl={hl?}&siteSearch={siteSearch?}&siteSearchFilter={siteSearchFilter?}&exactTerms={exactTerms?}&excludeTerms={excludeTerms?}&linkSite={linkSite?}&orTerms={orTerms?}&relatedSite={relatedSite?}&dateRestrict={dateRestrict?}&lowRange={lowRange?}&highRange={highRange?}&searchType={searchType}&fileType={fileType?}&rights={rights?}&imgSize={imgSize?}&imgType={imgType?}&imgColorType={imgColorType?}&imgDominantColor={imgDominantColor?}&alt=json"
},

}
],

}
]
},

},
"searchInformation": {
"searchTime": 0.299265,
"formattedSearchTime": "0.30",
"totalResults": "2900",
"formattedTotalResults": "2,900"
},
"items": [
// ... Search Result here
]
}
But how to obtain result of next page via nextPageToken ?

Answer 1

Instead of using nextPageToken, there are 2 parameters I can add into the query string to change the page of results:
start: the start index of the result, valid values are integers > 0.
num: number of results per page, valid values are 1 ~ 10 (max 10 records can be obtained in 1 page)
Therefore to change to page 2, I have to issue:
start=11&num=10
in query string (given that record per page is 10).
Hope this helps.
