HTTP Client

Overview

The HTTP Client Node has two Methods of use. These are HTTP GET and HTTP POST.

HTTP GET

The HTTP GET Node.

HTTP GET creates a request and returns the response within the HTTP protocol. This is very useful when dealing with APIs. A more detailed explanation involving APIs can be found in the See Also section.

Attributes

Attribute	Type	Description
Remote IP	User Input	The HTTP endpoint (either a URL or IP address).
Remote Port	Int	The port value. For HTTP, the standard is 80.
Method	Drop-down	Either GET or POST, depending on the goal of the user.
Path	User Input	A specific path from the call being referenced in Remote IP. Usually, this is the text after the main root URL but before the ? character.
Authentication	Drop-down	The user selects Basic when a username and password are required to access the information, otherwise None is chosen.
Default Headers	Add Elements	HTTP headers in the form of key/value pairs.
Request Query	Add Elements	Parameters of the call in the form of key/value pairs.
Response	Bool	The user chooses true or false depending on if the response body is binary or not. Currently, the Node only supports Strings.

Inputs

Input	Type	Description
Pulse Input (►)	Pulse	A standard Input Pulse, to trigger the execution of the Node.
Remote IP	String	The HTTP endpoint (either a URL or IP address).
Remote Port	Int	The port value. For HTTP, the standard is 80.
Path	String	A specific path from the call being referenced in Remote IP. Usually, this is the text after the main root URL but before the ? character.
Headers	Dictionary	HTTP headers in the form of key/value pairs.
Query	Dictionary	Parameters of the call in the form of key/value pairs.

Outputs

Output	Type	Description
Pulse Output (►)	Pulse	A standard Output Pulse, to move onto the next Node along the Logic Branch, once this Node has finished its execution.
OnResponse (►)	Pulse	Flows to additional actions when there is a response.
Status Code	Int	A standard status code within the HTTP protocol. For example, 404 is when a page is not found.
Headers	Dictionary	Parameters of the call in the form of key/value pairs.
Body	String	The body of the response, usually including HTML text.

HTTP POST

The HTTP POST Node.

HTTP POST sends data, in this case the information from the Request Body, to the desired server as per the HTTP protocol. More information on the differences between POST and GET can be found in the External Links section. All Attributes and Inputs are the same as those for HTTP GET except for the addition of the following:

Attributes
