Starting from Maximo 7.6 or above. I see Maximo supports both REST API and SOAP. I do not understand the difference between them. I find that Maximo (Maximo Integration Framework) supports web service (SOAP) but Maximo still uses REST API. Can you help me?

  • Is your question a general SOAP vs. REST or do you only care about the two API's for Maximo? For the second one you'll likely do better in a [Maximo forum](https://www.ibm.com/developerworks/community/groups/service/html/communitystart?communityUuid=86e48e5e-4ee6-4fa2-a408-6311e401e19f) than here. For the first, take a look at [this post](https://stackoverflow.com/questions/19884295/soap-vs-rest-differences). – stdunbar Oct 07 '18 at 19:38

  • If I can say so kindly, this question is way too open ended and shows no effort to find answers. A basic search for "REST vs SOAP" on Google turned up a great post on SO that answered the question. – Preacher Oct 22 '18 at 21:34

You can use both indeed. There are huge possibilities for REST clients using Maximo REST web server, the REST clients can get/update/delete data in Maximo (https://developer.ibm.com/static/site-id/155/maximodev/restguide/Maximo_Nextgen_REST_API.html). It is already implemented and you can setup REST support in Maximo (make it available for use) by changing few xml configuration files. REST services are "build in", you can't modify them.

External REST APIs can be called by using a configured HTTP end point in Maximo Integration.

You can create your own SOAP web-service by Click->Next->Click :) from Object Structure in Maximo Integration and provide generated by Maximo WSDL for SOAP client.

  • So, What's the difference between them?. Why Maximo support both?. When to use rest?. When to use SOAP service?. Thanks – Tu Trinh Oct 19 '18 at 03:55

    it depends pretty much on the requirements and the possibilities of the system you are going to integrate with. – Anna van den Akker Oct 20 '18 at 08:24

    Maximo supports both because Maximo is good software; it goes the extra mile to make it easier to integrate with whatever system the customer needs to integrate it with. If those systems need SOAP, Maximo can do that. If they need REST, put a check in that box. Given the choice, I would go with REST, because it's easier. – Preacher Oct 22 '18 at 21:24
  • For the difference between REST and SOAP and when to use which, see [this SO post](https://stackoverflow.com/questions/19884295/soap-vs-rest-differences). – Preacher Oct 22 '18 at 21:30
