Get Service Details Using Services URL
To demonstrate how to retrieve service information, we will be using Postman, but you can use any API testing tool for this.
Retrieve All the Available Services
You can use the Services URL to get the list of available services along with their details. For example, if your package has three services, you can retrieve the service details of all three services.

Execute the Service
Using the Execute Url, we can execute the service and retrieve output from our Google Cloud Function deployed in Google.
Request
- URL: <Execute Url>
e.g. https://us-west2-fr-project-305102.cloudfunctions.net/age-service-132658713990376521/Execute/age-service/1/person growing state/1?code=i7shHfdqjFwzrxvQAFN3QV1B+8Oi+xDzruHl2pcbHhpR2+rp/A97rrUbaPLTSPyRMBSQB0k6PB9G3gmY6x/9lA== - Request type: POST
- Body: <input of your service>
For the request body, the original input should be re-formatted as below, surrounded by an inputs tag. If you use the original input instead, it will give an error with the message, “Incorrect number of parameters specified.”{
"inputs": [
{
"name": "person",
"value": {
"Age":50,
"Title": null
}
}
]
}
The original input
{
"person":
{
"Age":50,
"Title":null
}
}
Response
It will run the app deployed in Google Cloud, and provide the results accordingly. In this example, since we entered 50 as age, it returned ‘Kid’ as the title. In the decision table, you can see that we have defined the age group 39-99 as ‘Kid’.
