Overview​

Received data in an object than perform a math operations to convert bandwidth percent remaining to bandwidth percent used

Tutorial


Supporting Concepts​

Basic concepts needed for the use case
TopicDescription
APIAn API in API AutoFlow is simply an OpenAPI model
ServerA server accepts and handles the request and response.
SimulationData simulation is a mock data simulated for the purpose of visualizing the data in every step of the workflow.
  • Simulated data is NOT the real data but a sample data you create.
  • To use real data, use the Transaction feature to capture the data you send from Postman or CURL.
ScopeA scope is a namespace for variables.
Data TypesData types describe the different types or kinds of data that you are gonna store and work with.
Use case specific concepts
TopicDescription
Action
math/calculate		Calculate mathematical expression.

Detail​

The HTTP request has an input:

{
    "bandwidth-percent-remaining" : 60
}

The goal of the operation is to convert both the key and value. The value needs to go through match calculation:

{
    "bandwidth-percent-used": 40
}

Content​

INPUT: HTTP Request​

1: Create an API endpoint​

Required Concepts

Learn how to create an API.

Create an API

From the left navigation, go to the API section and create a new API.

Create API
  • ID: sample-data-transformation
Create an API Path
Create API Path
  • Path: /obj-values-math-operation
  • Method: POST

2. Create a Server Operation​

Required Concepts

Learn how to create a Server.

Create a Server

From the left navigation, go to the Server section and create a new Server.

Create Server
  • Server ID: sample-data-transformation
  • Port Number: 1114 Feel free to select your own port number
  • Linked API: sample-data-transformation (select the API you created above)
Create a Server Operation
Create Server Operation
  • Press the "Add API Operation"
  • Select the API endpoint created above

3 : Create Data Simulation using Real Data​

Required Concepts

Learn how to create a Simulation.

We will use the "real data" to create the test simulation.

1. Send a HTTP request from Postman or CURL
Send Postman Request

API Autoflow Postman Collections

cURL​
curl --location 'localhost:1114/obj-values-math-operation' \
--header 'Content-Type: application/json' \
--data '{
    "bandwidth-percent-remaining" : 60
}'
2. Check the data is received by the server endpoint

API Autoflow captures the data received and it can be used to create data simulation.

Simulation

Action(s)​

Required Concepts

Learn how to create a Actions.

Add actions to transform the data.

1. Apply to perform 100 minus the input value.​

Math Calculation
SETTINGS​
Math Calculate

expression: string 100 - input
variables: data

input: data [request body > bandwidth-percent-remaining]

OUTPUT​

variables: output

OUTPUT: HTTP Response​

1. Create a NEW object and map the IP and Subnet​

Since we need to respond in a JSON object, we can create a new object in the HTTP response.

HTTP Response
SETTINGS​
HTTP Output

body: object

bandwidth-percent-used: data
[variables: output]

Mapping the action output to the HTTP response output
  • Data referenced in HTTP response is what gets sent back to the client.
  • Map the output from the actions to be sent back.

NOTE: By default, the action output is set to variable output. If you intend to keep each action's output without it being overwritten by the next action, simply rename the output location in the action's output.

2. Test the API with Postman or CURL​

cURL​
curl --location 'localhost:1114/obj-values-math-operation' \
--header 'Content-Type: application/json' \
--data '{
    "bandwidth-percent-remaining" : 60
}'
