Properties

Property Name Description
RequestAccessMode Determines how to access Request URL

Available Options (Use numeric value listed in bracket if you have to define expression on this property (for dynamic behaviour).

Option Description
DirectUrl [0] Direct Url
UrlFromVariable [2] Url from variable
UrlFromConnection [3] Url from connection
RequestUrlVariable Variable name which holds request URL
SupportConnectionLessUrl
EnableStatusCheck Enable status check loop. When this option is enabled web requests are tried every N seconds to check desired value in response. Once desired value is found response is returned. Error is returned if failure indicator found or timeout occurs (i.e. Max iteration reached and still no success value found in the response).
StatusCheckMaxWaitSeconds Maximum wait time in seconds until we need to keep checking for success value or failure value indicator.
StatusFieldFilterType Extract type for success value / failed value field. For JSON Examples: $.status.value,  For Xml Examples: ./AuthInfo/Token/text()  --or-- ./Auth/@Token --or-- //*[local-name() = 'ResponseData']

Available Options (Use numeric value listed in bracket if you have to define expression on this property (for dynamic behaviour).

Option Description
None [0] None
Json [1] Json
Xml [2] Xml
Regex [3] Regex
StatusFieldFilterExpr
StatusCheckIterationWaitSeconds Wait time between each iteration for status check
StatusCheckForFailedValue Enable check to look for failure indicator. By default only SuccessValue is searched in response unless you set this option to true. Set StatusFailedValue to indicate failure regex / string pattern.
StatusSuccessValue Regex pattern or string value you like to search for Success indicator (e.g. Done|Success|Ok ). If you dont want to use Regex match then change StatusFieldFilterType.
StatusContinueValue Regex pattern or string value you like to search to continue status check (e.g. Done|Success|Ok ) If this value is found then status check is continue without checking for success or failure value. If you dont want to use Regex match then change StatusFieldFilterType.
StatusFailedValue Regex pattern or string value you like to search for Failure indicator (e.g. Cancelled|Aborted|Failed ). Set StatusCheckForFailedValue=true to use this value. If you dont want to use Regex match then change StatusFieldFilterType.
IsMultiPartUpload Check this option if you want to upload file(s) (i.e. POST RAW file data) or send data using Multi-Part encoding method (i.e. Content-Type: multipart/form-data). Multi-Part request allows you to mix key/value and upload files in same request. On the other hand raw upload allows only single file upload (without any key/value)

==== Raw Upload (Content-Type: application/octet-stream) =====  
To upload single file in raw mode check this option and specify full file path starting with @ sign in the Body (e.g.  @c:\data\myfile.zip )

==== Form-Data / Multipart Upload (Content-Type: multipart/form-data) =====  
To treat your Request data as multi part fields you must specify key/value pairs separated by new lines into RequestData field (i.e. Body). Each key value pair is entered on new-line and key/value are separated using equal sign (=). Preceding and trailing spaces are ignored also blank lines are ignored.
If field value has some any special character(s) then use escape sequence (e.g. For NewLine: \r\n, For Tab: \t, For at (@): \@). When value of any field starts with at sign (@) its automatically treated as File you want to upload. By default file content type is determined based on extension however you can supply content type manually for any field using this way [ fieldname.Content-Type=some content type ]. In below example we have supplied Content-Type for file2 and SomeField1, all other fields are using default content-type.
See below Example of uploading multiple files along with additional fields.

file1=@c:\data\Myfile1.txt
file2=@c:\data\Myfile2.json
file2.Content-Type=application/json
SomeField1=aaaaaaa
SomeField1.Content-Type=text/plain
SomeField2=12345
SomeFieldWithNewLineAndTab=This is line1\r\nThis is line2\r\nThis is \ttab \ttab \ttab
SomeFieldStartingWithAtSign=\@MyTwitterHandle
AddMultiPartPostamble Some API server requires Multi-Part Requests to be ended by new line characters (i.e. \r\n). Enable this option if you face error such as - Unexpected end of MIME multipart stream. MIME multipart message is not complete -
PreventAutoRedirect By default HTTP 301 and 302 redirects are allowed. For some reason you want to disable it then set this option.
RequestTimeoutMs HTTP request timeout in milliseconds. Enter 0 to use system default timeout.
SecurityProtocol Specifies which security protocol is supported for HTTPS communication. Using this option you can enable legacy protocol or enforce to use latest version of security protocol (Note: TLS 1.2 is only supported in SSIS 2014 or Higher).

Available Options (Use numeric value listed in bracket if you have to define expression on this property (for dynamic behaviour).

Tls11Plus [6] TLS v1.1 or higher
Tls12 [7] TLS v1.2
Tls12Plus [8] TLS v1.2 or higher
EnableCompressionSupport Enable support for gzip or deflate compression. When you check this option compressed response automatically de-compressed saving bandwidth. This option is only valid if web server supports compressed response stream. Check your API documentation for more information.
AllowUnsecureSuite AllowUnsecureSuite
IgnoreCertificateErrors IgnoreCertificateErrors
RequestUrl Request URL where you want to submit HTTP Request
RequestUrlConnection HTTP Connection Manager for WebRequest to specified URL
RequestMethod Request method (e.g. GET, PUT, POST...)
RequestContentType Specifies content type for data you wish to POST. If you select Default option then system default content type will be used (i.e. application/x-www-form-urlencoded). If you specify Content-Type header along with this option then header value takes precedence.

Available Options (Use numeric value listed in bracket if you have to define expression on this property (for dynamic behaviour).

Option Description

File [1] Save to File
SaveAsBinary Treat response data as binary data rather than text data. Check this option when you downloading data which is not in text format or doesn't have encoding (e.g. zip, mp3, jpeg). This option is not available when you save response to Variable. When this option is checked ResponseCharset option is ignored.
ResponseDataFilePath File path where response content should be saved
ResponseHeaderMappings Http response header mappings
ResponseCookieMappings Cookie mapping. Use this setting to map cookie value to variable
CookieContainerVariable Cookie Container can be used to maintain state between multiple web requests. Example: You can login to site like wordpress and then extract any private page content by simply passing authentication cookies using this variable.
ConvertXmlToJson Convert XML Response to JSON. This setting is helpful to consume services which support XML format but not JSON. By converting XML to JSON you can then consume data using other components/tasks such as JSON Source, JSON Parser.
ResponseDataVariable Variable name where response content should be saved
ResponseStatusCodeVariable Variable name where you want to save response status code
ResponseContentType Response content type

Available Options (Use numeric value listed in bracket if you have to define expression on this property (for dynamic behaviour).
