Our Enterprise plan allows for using the REST Reporting API to retrieve responses data from the Informizely server using HTTP requests.

In order to use the REST Reporting API, you need an API Key and an API Secret. These can be found on the "My Account" page in your dashboard, if your subscription plan allows usage of the REST Reporting API. If no API Secret has been set, you can click the "Generate" link to create one. The REST Reporting API uses HTTP Basic Authentication. This means that the API Key and Secret are sent in the HTTP header in Base64-encoded form: "[api-key]:[api-secret]". You can encode them yourself or use the "API Credentials" that are shown on the "My Account" page, which are just the Base64-encoded string "[api-key]:[api-secret]".
All communication requires HTTPS, so all data is sent to the Informizely server in encrypted form. The base URL for the REST Reporting API is https://api.informizely.com/api/v1.
Data can be requested in either JSON or XML format.

The generic form of a request URL is:
https://api.informizely.com/api/v1/[request]?[parameters].
Multiple parameters must be separated by '&'. Optionally, an 'id' parameter can also be specified unnamed after a '/':
https://api.informizely.com/api/v1/[request]/[id]?[other-parameters].
Example:
https://api.informizely.com/api/v1/responses/luodyjklq?fromDate=2017-08-01T00:00:00Z&excludeQuestions=true. Date types should be specified in UTC, in ISO 8601 format: yyyy-MM-ddTHH:mm:ssZ (the "Z" makes it UTC).
Boolean types should be specified as either true or false. For ease of definition we specify the returned objects as C# classes, which will be serialized to either JSON or XML in the result returned by the server.

A survey's ID is shown on the survey's "Settings" page, as the first property of the survey. The survey ID is also the part after the last '/' in the browser's page URL. You can also use the sites request to retrieve a list of all of your account's site IDs and survey IDs. If you want to, you can test the REST Reporting API without writing integration code first.

To test in curl:
curl -u [api-key]:[api-secret] -X GET https://api.informizely.com/api/v1/[request]?[parameters]
For example, to show all responses for the survey with ID luodyjklq, the URL would look something like:
curl -u IuZjFvXj:JkuLerv2 -X GET https://api.informizely.com/api/v1/responses?id=luodyjklq

To test in Fiddler, you add the API URL in the composer: https://api.informizely.com/api/v1/[request]?[parameters], and add the following as header data:
Accept: text/json
Authorization: Basic [api-credentials]
[api-credentials] is simply the Base64-encoded string "[api-key]:[api-secret]", which you can retrieve from the "My Account" page, or encode yourself using Fiddler's TextWizard. If you want to retrieve XML, you can use Accept: text/xml.

We conclude with an example of how to retrieve response data using jQuery:

$.ajax({
    type:       "GET",
    url:        'https://api.informizely.com/api/v1/responses',
    parameters: { id: 'luodyjklq', fromDate: '2017-08-01T00:00:00Z', excludeQuestions: true },
    dataType:   "json",    // or "xml"
    beforeSend: function(xhr) {
        xhr.setRequestHeader("Authorization", "Basic [api-credentials]"));
    },
    success:    function(result) {
        // Process the returned data.
    }
});
