Tutorial: paging through historical Mentions

Downloading data from your query by paging through it.

Another common integration use case is to request pages of Mentions within a date range and then page through them all. You may want to use this approach if you want to download a substantial dataset from your Query into your own integration.

In this tutorial, we'll take the following approach:

  1. We will request for a batch of Mentions across a specified date range.
  2. We will then use the paging functionality to access historical data.

In this tutorial we will assume that the application has already logged in and has a token.

Requesting Mentions for a given date range

In a similar manner to the other tutorial on polling for new Mentions, we'll begin by requesting the newest page of Mentions within a date range.

We'll use the following parameters to achieve this:




This returns 100 Mentions per request. You can change this to a value that suits you. We do not recommend getting more than 5000 at a time.



This sets the page market to the latest page, which is indexed from 0.



This orders the Mentions by their resourceId, which is a global counter incremented for every new Mention that we crawl.



This changes the sort direction to descending, ensuring that the newest result is returned first.

Here is the request as a cURL command:

curl -X GET https://api.brandwatch.com/projects/289733322/data/mentions?queryId=348973733&startDate=2016-05-01&endDate=2016-05-02&pageSize=100&page=0&orderBy=id&orderDirection=desc

This will return a list of Mentions, newest first. The following example response has had the Mentions removed for brevity.

  "resultsTotal": 9982,
  "resultsPage": 0,
  "resultsPageSize": 100,
  "results": [...],
  "maximumId": 100057070129,
  "maximumIdInResult": 100057070129,
  "startDate": "2016-05-01T00:00:00.000+0000",
  "endDate": "2016-05-02T00:00:00.000+0000"

We can see from the result that there were a total of 9982 returned for that date range, and we are beginning on resultsPage 0, with a resultsPageSize of 100 as per our request.

Iterating through all available pages

After the first response, the client should store:

  • The current page (identified by resultsPageSize: 0)
  • The number of results returned across the whole date range (identified by resultsTotal: 99382)

Then, you can compute the number of pages that you have to iterate through by applying the following calculation:

pagesToIterate = ceiling(resultsTotal/resultsPageSize)

In this particular case, the pagesToIterate will be 100.

Then, iterate through each page by requesting for Mentions and explicitly passing the page. For example, in order to get the next page we pass the parameter page as 1:

curl -X GET https://api.brandwatch.com/projects/289733322/data/mentions?queryId=348973733&startDate=2016-05-01&endDate=2016-05-02&pageSize=100&page=1&orderBy=id&orderDirection=desc

Continue iterating over the page numbers until you have retrieved all pages of Mentions data.
