Conditional IF Example

Apply condition to the incoming number.

• IF the number is greater than 10: multiply by 10.
• ELSE: reply with a message "The number is not great than 10".

Supporting Concepts

Basic concepts needed for the use case

Topic	Description
API	An API in API AutoFlow is simply an OpenAPI model
Server	A server accepts and handles the request and response.
Simulation	Data 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.
Scope	A scope is a namespace for variables.
Data Types	Data types describe the different types or kinds of data that you are gonna store and work with.

Use case specific concepts

Topic	Description
Action conditional/IF	Returns values that fits the condition.
Action math/calculate	Calculate mathematical expression.

Details

Send JSON object with a key condition over HTTP request body.

The goal of the operation is to run a conditional logic:

• IF greater than 10

An action is added to perform a math calculation of multiplying by 10.

For example, if the input number is 15, the output is

150

• ELSE Return

A string value.

The number is not great than 10.

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.

• ID: sample-conditional

Create an API Path

• Path: /if
• 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.

• Server ID: sample-conditional
• Port Number: 1113 Feel free to select your own port number
• Linked API: sample-conditional (select the API you created above)

Create a 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

API Autoflow Postman Collections

cURL

curl --location 'localhost:1113/if' \
--header 'Content-Type: application/json' \
--data '{
    "condition": 15
}'

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.

Action(s)

Required Concepts

Learn how to create a Actions.

Add actions to transform the data.

1. Apply condition to the input data

IF condition works based on truthy value. There are a few options in getting the boolean result.

(IF): Greater than 10

In this example, we will use the "Value type selector / Comparison" greater-than to compare the HTTP request body with a number "10".

The two number to compare:

• 1st number: Data from request body condition field
• 2nd number: 10

SETTINGS

IF: Comparison

data
[request: body > condition]

is greater than to:

number
10

Multiply by 10

Math Calculate

SETTINGS

expression: string

10 + number

variables: object

number: data

[request: body > condition]

OUTPUT

variables: output

(Else): Return message

SETTINGS

Return: string

Number is less than 10

OUTPUT

variables: output

OUTPUT: HTTP Response

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

Both the action's output and HTTP response body are set to variables: output. There's no change that needs to be made.

HTTP Response

SETTINGS

body: 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:1113/if' \
--header 'Content-Type: application/json' \
--data '{
    "condition": 15
}'
