Iteration Filter

Iterate over an array of numbers.

Then, filters out number(s) larger than 3.

Example Configuration

Learn how to use

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 iteration/filter	Iterate over array of data filtering for each truthy value.
Action condition/is-larger-than	Returns true or false if the given value is larger than or equal to the target..

Details

The HTTP request body has an array with 4 values:

Original array

[ 1, 2, 3, 4 ]

The goal of the operation is to iterate over the array and create a new array:

New array (after iteration)

[ 1, 2 ]

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-iteration

Create an API Path

• Path: /filter
• 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-iteration
• Port Number: 1112 Feel free to select your own port number
• Linked API: sample-iteration (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:1112/filter' \
--header 'Content-Type: application/json' \
--data '[
    1,
    2,
    3,
    4
]'

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. Iterate over the input array.

Required Concepts

Learn how to create a Iteration/filter.

Iteration Filter

SETTINGS

Iteration: data

[request: body]

Scope: string

loop-var

Iteration Scope

Scope loop-var stores each value from the array.

• Makes the value available inside the iteration one-by-one. The 1st value is available to be used for configuration.

Check if the value is larger than 10

Condition Is Larger Than Or Equal To

SETTINGS

value: number

2

target: data

[loop-var: value]

OUTPUT

variables: output

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:1112/filter' \
--header 'Content-Type: application/json' \
--data '[
    1,
    2,
    3,
    4
]'
