HTTP Request

The HTTP Request Wizard Window

• End Point - The URL to which you want to make the request. Custom segments have to be placed between braces "{}" and defined in the Parameters section. For example, this URL https://platform.uipath.com/odata/Robots(28) can be written as https://platform.uipath.com/odata/Robots({id}), and the value of the id parameter can be provided in the Parameters section, as a UrlSegment.
• Preview URL - A preview of the URL provided in the End Point field, taking into account the information provided in the Parameters section.
• Enable SSL certificate verification - Check this box to verify SSL certificates when sending a request. Verification failures will result in the request being aborted.
• Timeout - Specifies the amount of time (in milliseconds) to wait for the activity to run before an error is thrown. The default value is 6000 milliseconds (6 seconds).
• Client Certificate - The location in which the Client Certificate file is stored. The full path must be provided. The supported certificate encoding is X.509 and the supported extensions are .pfx and .p12. It supports two-way handshake verification.
  Note: The path must not be written between quotation marks.
• Client Certificate Password - The password that corresponds to the Client Certificate file you are using.
• Request Method - The request method to be used when calling the API. The following HTTP verbs are supported: GET, POST, PUT, DELETE, HEAD, OPTIONS, PATCH and MERGE. By default, the GET method is selected.

• Authentication - Specifies the authentication protocol to be used when calling the API. The following protocols are supported:

  • None - The default option. It should be used if the web server you are sending requests to does not require an authentication protocol.
  • Simple Http - This option has to be selected if the API you are making requests to uses a simple HTTP authentication protocol. If chosen, two additional fields are displayed - Username and Password, which have to be filled in with valid credentials for the specified API.
  • OAuth1 - This option has to be selected if the API you are making requests to uses an OAuth1 protocol. If chosen, four fields are displayed: Consumer Key, Consumer Secret, Access Token, Access Token Secret.
  • OAuth2 - This option has to be selected if the API you are making requests to uses an OAuth2 protocol. If chosen, the Access Token field is displayed. This access token is usually generated as a response to another HTTP request to the indicated API.

• Add Parameter - Adds a new line in the Parameters table, with the GetOrPost type. A new line is not added if the previous line is not filled in.

• Add Header - Adds a new line in the Parameter table, with the HttpHeader type. A new line is not added if the previous line is not filled in.

  Note: In the case where you want to add multiple values for a header, they must be concatenated through a comma (,).
• Add URL Segment - Adds a new line in the Parameters table, with the UrlSegment type. A new line is not added if the previous line is not filled in.
• Delete - Removes a selected line in the Parameters table. If a line is not selected, this button is disabled.

• Name - The name of the parameter, header or URL segment.
• Value - The value of the parameter, header or URL segment.

• Type - The type of line. The following options are available:

  • GetOrPost - Indicates that the line is a parameter that can be used in requests.
  • HttpHeader - Indicates that the line added in the Parameters table is a request header to be sent when making the API call.

  • UrlSegment - Indicates that the line added is a fragment or the URL provided in the End point field.

    Note: In some cases, an error might be returned stating that duplicate parameters cannot exist. These may be caused by authentication requests that need to contain the Password and Username parameters. In these cases, we recommend passing them using the Body property.

• Add Attachment - Enables you to add a file to the HTTP request performed, by creating a new line. Enabled only when the Request Method is set to POST or PUT.
• Delete Attachment - Enables you to delete a previously added line, in the Attachments section.
