How relevant, verifiable metrics drive AIMultiple’s rankings

AIMultiple uses relevant & verifiable metrics to evaluate vendors.

Metrics are selected based on typical enterprise procurement processes ensuring that market leaders, fast-growing challengers, feature-complete solutions and cost-effective solutions are ranked highly so they can be shortlisted.
Data regarding these metrics are collected from public sources as outlined in the “What are AIMultiple’s data sources?” section of this page.


There are 2 ways in which vendor metrics are processed to help prioritization:
1- Vendors are grouped within 4 metrics (customer satisfaction, market presence, growth and features) according to their performance in that metric.
2- Vendors that perform high in these metrics are ranked higher in the list.


The data used in each vendor’s ranking can be accessed by expanding the vendor’s row in the below list.
This page includes links to AIMultiple’s sponsors. Sponsored links are included in “Visit Website” buttons and ranked at the top of the list when results are sorted by “Sponsored”. Sponsors have no say over the ranking which is based on market data. Organic ranking can be seen by sorting by “AIMultiple” or other sorting approaches. For more on how AIMultiple works, please see the ethical standards that we follow and how we fund our research.

Which human resources API solution provides the most customer satisfaction?

While deciding a product's level of customer satisfaction, AIMultiple takes into account its number of reviews, how reviewers rate it and the recency of reviews.

  • Number of reviews is important because it is easier to get a small number of high ratings than a high number of them.
  • Recency is important as products are always evolving.
  • Reviews older than 5 years are not taken into consideration
  • older than 12 months have reduced impact in average ratings in line with their date of publishing.

3. HR APIs make a company all around more connected. The HR employees can use API integrations and tools to manage time-consuming processes such as onboarding more efficiently.
4. An HR ecosystem with APIs can customize workflows if the organization needs it.
5. HR APIs can lessen the amount of duplicate data entry and allow companies to coordinate demanding procedures more effectively.
6. According to McKinsey, 40% of companies decreased their HR costs using AI. HR APIs are an essential step to accelerate the digitization in HR and provide a better use of new technologies in HR.

Some use cases of human resources APIs include:

  • Returning real-time data for human resources
  • Tracking hiring processes
  • Employee time tracking
  • Improving onboarding and offboarding

APIs can be used to return data for HR managers. Moreover, APIs can be used to get information to display:

  • Competitors
  • Locations
  • Job openings
  • Assignments
  • Employee data
  • Pay periods.

With APIs, users can get access to employee information more easily. Such APIs can be used to create employee directories, update records, and optimize companies’ organizational structure.

API example: Paychex API

According to PwC, the recruiting and hiring process accounts for 39% of the HR department’s challenges. Companies can use API services to track and manage candidates’ applications and the hiring process. The users can create and manage open positions in all job boards with a single API. With API methods and management systems, the applicant tracking system via API provides a better employee and applicant experience, improving HR technology in the process.

API example: Catsone API

Time tracking is the process by which businesses keep track of employee’s working hours and ensure they are fairly compensated for their time. It is a part of the larger area of time and attendance, broadly referring to time monitoring and other aspects, including attendance, vacation time, billable hours, and scheduling.

Companies must manage the time tracking of their employees. HR APIs provide users with time-tracking services built around face recognition, cloud technology, and shift schedules.

API example: Fareclock

Considering that only 12% of employees describe their onboarding process as good, many organizations need an improved and more efficient onboarding and offboarding experience for both their employers and newcomers.

Certain APIs make the onboarding process more organized and efficient by keeping the new hires engaged, reducing paperwork, and focusing on introductions.
