How to post HTTP requests using Automation script?

23 September 2021 / / 9 Comments

I want to post a simple JSON message to an external system and do not want to add any external library to Maximo as it would require a restart.

In the past, I used the Java HTTPClient library that comes with Maximo, but it would require half a page of boilerplate Jython code. Recently, I found a simpler solution below.

Step 1

First I use WebHook as a mock service for testing. Go to webhook.site, it will give us a unique URL to send request to:

    Step 2

    Go to the End Point application in Maximo to create a HTTP Endpoint

    • End Point Name: ZZWEBHOOK
    • Handler: HTTP
    • Headers: Content-Type: application/json
    • URL: <copy/paste the Unique URL from webhook>
    • HttpMethod: POST

    Step 3

    To ensure it’s working, Use the Test button, write some simple text, then click on “TEST”. Maximo should show a successful result. In Webhook, it should also show a new request received. (Note: if it gives an error related to SSL, it’s because Websphere doesn’t trust the target website. You’ll need to add the certificate of the target website to Websphere trust store)

    Step 4

    To send a request, just need two lines of code as follows:

    Process Inbound Twilio SMS message in Maximo

    In my previous post, I provided some demos on how we can process inbound text messages to create SR and route Workflow. There are a few people on LinkedIn asked me how to do it. I also like to explore the option of integrating Maximo with Twilio directly without the need for AppConnect. With Maximo 7.6, we can create a simple API using automation script. To prove the concept, the video demonstrates how we can create a simple API with automation script and direct Twilio HTTP requests to Maximo:


    Below is the source code for the script in the video:

    In this case, for the sake of simplicity, I only include the bare minimum components to make it works. You will probably want to write some scripts to automatically populate the “Reported By” person based on source phone number and populate other details like location/asset number based on the content of the incoming message. Also, it would be nice to respond with a text message for confirmation and provide the users with the new SR number.

    With this method, we’ll need Maximo to be accessible from the Internet, it’s is not a problem for a cloud-based system. But if you have an onpremise system, you’ll need to configure port-forwarding to make Maximo accessible from the Internet. For development, since my ADSL router does not support port-forwarding, I used a tool called ‘ngrok’ to forward access of my local Maximo to the web via ngrok.io

    The Scripted API is a new feature in Maximo 7.6. Thus this approach won’t work if you have an older Maximo version. It that case, probably using App Connect is an easier option. With App Connect, I used it for two functions:

    • Act as an API gateway to route Twilio request to a local server
    • Quickly transform HTTP request to REST/JSON request which Maximo can easily consume

    App Connect is just a fancy name for a newer version of IBM Integration Bus (which IBM now call it App Connect Enterprise) and a bunch of new cloud-enabling features. So you’ll need some basic understanding of IIB in order to set it up. For connecting App Connect (the cloud component) and local Integration server, I followed the tutorial here: link
