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".

Example Configuration

Learn how to use

Supporting Concepts

Basic concepts needed for the use case
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
Returns values that fits the condition.
Calculate mathematical expression.


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


A string value.

The number is not great than 10.



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-conditional
Create an API Path
Create 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.

Create 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
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 --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.



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
Conditional IF

IF: Comparison

[request: body > condition]

is greater than to:

Multiply by 10
Math Calculate
Math Calculate

expression: string

10 + number

variables: object

number: data

[request: body > condition]


variables: output

(Else): Return message
Conditional Else

Return: string

Number is less than 10


variables: output


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
Server Workflow Default Output

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