Developers & API Documentation

Feng-GUI has an open web Application Programming Interface.
This means that you can integrate your own program with Feng-GUI services.
Feng-GUI API partners vary from digital marketing agencies through e-mail-marketing vendors to packaging design vendors.

Developing on the Feng-GUI API

Anyone can write software to do cool stuff with available Feng-GUI technology via our API.
Here's how to get started:
1. Review and agree to the API license agreement.
2. Read the API documentation below. Feel free to send us some feedback.
3. Request for an evaluation API account. email to: sales@feng-gui.com to add the 'api' role to your account
4. After you have learned how to use API, build your own application.

Roles

A Role indicates the levels of permissions a user have while operating a method.
Your account is associated with one or more Roles.
Account Roles depends on package plans and the Feng-GUI partnership level you have.

Authentication

Feng-GUI services required HTTP Basic authentication for all methods.
HTTPS/TLS must be used in conjunction with HTTP Basic authentication.

Storage

To perform an action using the API, you need to invoke a SOAP or JSON-RPC request to its endpoint specifying a method and some arguments, and will receive a formatted response.

SOAP format

The SOAP service Endpoint URL is: https://service.feng-gui.com/soap/api.asmx
SOAP service description (WSDL) is at https://service.feng-gui.com/soap/api.asmx?wsdl
SOAP service test page is: https://service.feng-gui.com/soap/api.asmx

SOAP Request

The following is a sample SOAP 1.2 request. The placeholders shown need to be replaced with actual values.
To send a request (for example, 'echo' method), send a request like this:

POST /soap/api.asmx HTTP/1.1
Host: service.feng-gui.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://www.feng-gui.com/echo"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  <soap:Body>
    <echo xmlns="http://www.feng-gui.com/">
      <value>string</value>
    </echo>
  </soap:Body>
</soap:Envelope>

SOAP Response

The following is a sample SOAP 1.2 response. The placeholders shown need to be replaced with actual values.
A request call to the echo method returns this response:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

Credit: no credit is charged when using this method.
Method applies to image analysis.

Arguments

ImageID (String): The relative file name of the original image or video URL including the file extension .png or .mp4

   https://service.feng-gui.com/users/USERNAME/files/images/folder/uuid.png
AOIs (String)
   JSON format string of the AOIs regions.

Example

To generate an AOIs report:
1. Call ImageAttention method with the URL of the image located on your server.
2. From ImageAttention response, extract the newly created ImageID from the OutputImage URL
Here is an example of OutputImage URL
https://service.feng-gui.com/users/USERNAME/files/images/uuid_heatmap.png
The ImageID is uuid.png

3. Use this ImageID and a JSON AOIs string to call SetImageAOIs(string ImageID, string AOIs)
Here is an example of an AOIs string

AOIs = '[{"units":"pixels","top":36,"left":75,"width":40,"height":40,"text":"face","id":"uuid1"},
{"units":"pixels","top":3,"left":220,"width":40,"height":50,"text":"product","id":"uuid2"},
{"units":"pixels","top":82,"left":14,"width":40,"height":40,"text":"face2","id":"uuid3"},
{"units":"pixels","top":0,"left":3,"width":32,"height":20,"text":"company name","id":"uuid4"},
{"units":"pixels","top":212,"left":317,"width":55,"height":23,"text":"brand name","id":"uuid5"},
{"units":"pixels","top":192,"left":221,"width":136,"height":25,"text":"tag line","id":"uuid6"}]'

4. Call ImageAttention method with the URL of the image located on Feng-GUI server. No credit is charged when analyzing images located on Feng-GUI server.
5. Download the AOIs report image with an additional timestamp parameter at the end of the URL. For example:
https://service.feng-gui.com/users/USERNAME/files/images/uuid_aoi.png + "?" + (new Date()).getTime();
The report files are http cached and if you will not add a random parameter (like timestamp) to the URL, you might receive an HTTP status "304 Not Modified"
