Ultimate's API management strategy employs an API gateway to manage quotas and rate limits for how many API calls an API client can make over a particular time period, normally 1 minute. If the rate of requests has been too high the server is not willing to accept this and will return to the API client an HTTP Status Code 429.

We are pleased to announce some important changes and services in this month's release...

Introducing Model Domains

Ultimate is restructuring our API solution/project structure to be domain based.

APIs are best thought of as a contract provided by Ultimate Software to its customers and internal developers. Customers or third-party developers and partners can work with our APIs to build integrations on their own systems. Sometimes it is necessary to phase out an API endpoint (or version). I.e. this may be necessary if a field is no longer supported in the result or a business functionality behind an endpoint has to be shut down. There could be other reasons as well.

Swagger is one of the leading standards in API documentation, it's been around ever since 2011 and is the product of SmartBear, the company that made a similar tool in SOAPUI. The community is pretty active and it currently support a wide range of languages: Clojure, Go, JS, Java, .Net, Node, PHP, Python, Ruby, Scala, for each of these languages many frameworks are supported.

Integrating with a partner's API can be a complicated process. Here at Ultimate Software, we strive to make your integration with our services as seamless as possible. For this reason, we recommend that your team use Postman to experiment and test out our services prior to integrating within your own applications.

Note: It should be understood that we are only using Postman for UltiPro's REST API's and it is not used with SOAP services.
