You can configure this function in the following settings.

Connection

Depending on the users' configuration, three authentication methods are available: None, Basic authentication and OAuth 2.0.

A selectable option from the Authentication type is used to make the selection and based on that separate configuration options are available. There will be additional options for the Authentication type selected.

Operational settings

In Operational settings, enter the following details that determine how you want to handle the errors.

In Request run limit, specify the number of times the operation should run.
In Action on error, specify the action you want to take in case of an error. You can select from the following options:

Any response with the HTTP status code 4xx or 5xx is considered an error. All errors get logged in the system logs. You can refer to the Logs for more information. The default value is Ignore.

General settings

In General settings, you select an HTTP request method from the following options:

HTTP Method	Description
GET	Request data from the target server.
POST	Sends data to the target server. Select either Body or Form under Content*.
PUT	Replaces the current resources of the target URL with the uploaded content. Select either Body or Form under Content*.
PATCH	Updates partial resources of the target URL. Select either Body or Form under Content*.
DELETE	Removes all current representations of the target resource.

Note!

*The Body and Form fields are visible only for request methods POST, PUT and PATCH. See Content for more information.

Include query string in URL – This enables a query string in the token URL.

Option

Description

Include basic access authentication credentials

Select to add the specified username and password.

Incude query string in URL

Select to include a query string in the URL. Add a key and its corresponding value. You can include multiple query strings.

Customize header

Select to customize the headers of the URL and specify multiple keys and their respective values.

The default value for the HTTP headers “content-type” and “accept” is application/json.

You can override the default value for the HTTP header “content-type.”

It is recommended that the default value for the HTTP header “accept” is left unchanged. The HTTP functions only support application/json.

Results

The support for response headers can be enabled by toggling the Enable response headers option. A default value for the key will be added by the engine (httpResponseHeaders) which will match the placeholder for the key input. Configuration is done by filling up the necessary input fields: Result headers Key and Result key.

HTTP Response Headers Support

By enabling response headers, the overall data size of the HTTP packets will also increase. Caching of the body checkbox is tied to the headers.

This option is available only for the HTTP Client collector and the HTTP Client Processor.

In Result key, you can assign a name to the result that you receive in response to the request. It is recommended to configure the resulting key to make future references of the same response easy and traceable. The default value is httpResponse.

Token Renewal Support

The collector and processor Functions support token renewal, if the servers return a 401 Token Expiry error.

Action on error options	Description
Ignore	Select to ignore the error and the stream keeps on running.
Stop the stream	Select to stop the stream.
