The limit and start parameter

Some API calls have optional start and limit parameters which you can add to the request. When requesting a large list of data, by default up to 100 records will be retrieved, starting from the first record in the table. The start parameter allows you to specify the position of the first record to be obtained. If, for example, you wish to start at record #10, add start=10 to the call, after the access_token. If you wish to increase the number of records obtained, add the limit=200 parameter to the call.

Example result of a default call:

    "start" = 5,
    "limit" = 2,
    "data"  = [ ... ]

In the above example only 2 records will be retrieved, and the first 5 records in the table will be ignored.

Fields[] requirement parameter

Some request methods have an (optional) fields[] parameter. This parameter enables you to make requirements on the data that is updated or received in the request.

The parameter is an array, thus each request can have multiple requirements. In PUT requests the fields[] parameter is mandatory. If this is the case, and the parameter is ommited, you get an error message back.

In a call with one or more field requirements, you can use the following comparison operators:

== equal to != not equal to \<> not equal to =\~ LIKE !\~ NOT LIKE \<= less than or equal to >= greater than or equal to

For example in a PUT request you must specify a fields[] parameter with the requirements, to ensure that only the profiles that meet these requirements are updated in the request.[]

If you want to update profiles with an email address only, use the LIKE operator.[]

The fields[] parameter is currently supported in the following requests:

  • GET collection subprofiles
  • GET database profiles
  • GET profile subprofiles
  • POST collection unsubscribe behaviour
  • PUT database profiles *
  • POST database unsubscribe behaviour
  • PUT profile subprofiles *

* mandatory in this request

Count parameter

The count parameter shows how many elements are in the data returned by the request. In other words: how many items matched your request. So, a /database/$databaseID/profiles request with default start and limit (respectively 0 and 100) to a database with 50 profiles will return the following:

    "start": 0,
   "limit": 100,
    "count": 50,
    "data": [
    "total": 50

Total parameter

At the end of every GET call you make, you see a parameter at the very bottom that says total:"some digit". This is the total number of items in the database or section you made the request to. While this often is useful information, it does make your request slower. If you don't need that information, you can make your request a lot faster by using the new total=false parameter in your request, which disables the count query. Your request will then look something like this:[]
