QuestionPro publishes API V2 along with documentation

Function of the QuestionPro API

With the QuestionPro API (Application Programming Interface), users of the survey, market research and experience management platform can connect a wide variety of applications, such as ERP, CRM or sales systems, to QuestionPro so that these applications can interact with each other. The primary interaction of external applications with QuestionPro takes place via a so-called API access key. This access key allows other applications to access your user account without a password.

What has changed?

REST architecture

We have extended our API to follow the REST architecture used by most SaaS platforms and is currently the best industry standard for APIs, i.e. for providing interfaces for connecting different applications to each other. REST stands for Representational State Transfer. What is meant by REST is a kind of mental model in which the architecture of interfaces should be developed so that systems can optimally interact with one another. REST technology is generally preferred over other similar technologies. This is usually the case because REST requires less bandwidth and is therefore better suited for efficient use.

Intuitive and safe

We use built-in HTTP features such as HTTP authentication and HTTP verbs to allow you to securely interact with our API from a client-side web application. All returned responses within an interaction are JSON objects. API V2 is also very intuitive and secure.

As seen below, the endpoints for accessing our email list in API V1 had a different structure and all followed a single HTTP protocol - the POST method. API V2 uses a single resource, leaving no room for confusion.

No system impact during and after API migration

The “conversion” of the interface architecture from API V1 to API V2 will have no impact on your everyday work with QuestionPro. Based on our regular security testing, we have not found any vulnerabilities including buffer overflow. We also have these tests carried out regularly by third parties. With an intuitive URL pattern, it's easier than before for our users to make calls and use QuestionPro features through other applications.
