EndPoint Generic Request

Name

generic_request

Description

This is generic endpoint. Use this endpoint when some actions are not implemented by connector. Just enter partial URL (Required), Body, Method, Header etc. Most parameters are optional except URL.

Parameters

Parameter

Label

Required

Options

Description

Url

YES

API URL goes here. You can enter full URL or Partial URL relative to Base URL. If it is full URL then domain name must be part of ServiceURL or part of TrustedDomains

Body

Request Body content goes here

IsMultiPart

Set this option if you want to upload file(s) using either raw file data (i.e., POST raw file data) or send data using the multi-part encoding method (i.e. Content-Type: multipart/form-data). A multi-part request allows you to mix key/value pairs and upload files in the same request. On the other hand, raw upload allows only a single file to be uploaded (without any key/value data). ==== Raw Upload (Content-Type: application/octet-stream) ===== To upload a single file in raw mode, check this option and specify the full file path starting with the @ 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 in the RequestData field (i.e., Body). Each key/value pair should be entered on a new line, and key/value are separated using an equal sign (=). Leading and trailing spaces are ignored, and blank lines are also ignored. If a field value contains any special character(s), use escape sequences (e.g., for NewLine: \r\n, for Tab: \t, for at (@): @). When the value of any field starts with the at sign (@), it is automatically treated as a file you want to upload. By default, the file content type is determined based on the file extension; however, you can supply a content type manually for any field using this format: [YourFileFieldName.Content-Type=some-content-type]. By default, file upload fields always include Content-Type in the request (non-file fields do not have Content-Type by default unless you supply it manually). If, for some reason, you don't want to use the Content-Type header in your request, then supply a blank Content-Type to exclude this header altogether (e.g., SomeFieldName.Content-Type=). In the example below, we have supplied Content-Type for file2 and SomeField1. All other fields are using the default content type. See the example below of uploading multiple files along with additional fields. If some API requires you to pass Content-Type: multipart/form-data rather than multipart/form-data, then manually set Request Header => Content-Type: multipart/mixed (it must start with multipart/ or it will be ignored). 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

Filter

Option	Value
No filter
Example1	$.store.books[*]
Example2 (Sections Under Books)	$.store.books[].sections[]
Example3 (Equals)	$.store.books[?(@author=='sam')]
Example4 (Equals - Any Section)	$..[?(@author=='sam')]
Example5 (Not Equals - Any Section)	$..[?(@author!='sam')]
Example6 (Number less than)	$.store.books[?(@.price<10)] Example7 (Regular Expression - Contains Pattern)=$.store.books[?(@author=~ /sam\|bob/ )]
Example8 (Regular Expression - Does Not Contain Pattern)	$.store.books[?(@author=~ /^((?!sam\|bob).)*$/ )]
Example9 (Regular Expression - Exact Pattern Match)	$.store.books[?(@author=~ /^sam\|bob$/ )]
Example10 (Regular Expression - Starts With)	$.store.books[?(@author=~ /^sam/ )]
Example11 (Regular Expression - Ends With)	$.store.books[?(@author=~ /sam$/ )]
Example12 (Between)	$.store.employees[?( @.hiredate>'2015-01-01' && @.hiredate<'2015-01-04' )]

Enter filter to extract array from response. Example: $.rows[*] --OR-- $.customers[*].orders[*]. Check your response document and find out hierarchy you like to extract

Headers

Headers for Request. To enter multiple headers use double pipe or new line after each {header-name}:{value} pair

Examples

SSIS

Use Power BI Connector in API Source component to read data or in API Destination component to read/write data:

Generic Request using API Source

Power BI

Generic Request

SSIS API Source - Read from table or endpoint

Generic Request using API Destination

Power BI

SSIS API Destination - Access table or endpoint

ODBC application

Use these SQL queries in your ODBC application data source:

Generics - A simple generic API request

SELECT * 
FROM generic_request
WITH (Url='/groups',
Filter='$.value[*]')


/*
EXPLANATION:
- This configuration calls Power BI REST API "Get Groups" endpoint and gets the Workspaces back.
- This is achieved by "/groups" value in the "Url" parameter.
- The SQL query parameter "Filter" uses JsonPath "$.value[*]".
- This gets JSON objects from "value" array and transforms them into SQL rows.

*/

Generics - A generic API request with URL parameter

SELECT * 
FROM generic_request
WITH (Url='/groups?$filter=contains(name,''MyWorkspace'') or name eq ''My Blue Workspace''',
Filter='$.value[*]')


/*
EXPLANATION:
- This configuration calls Power BI REST API "Get Groups" endpoint and gets the Workspaces back.
- This is achieved by "/groups" value in the "Url" parameter.
- Workspaces are filtered on the Power BI REST API side by using the "$filter" URL parameter.
- Only those Workspaces are returned that:
  > contain a string value "MyWorkspace" or
  > if the Workspace name is "My Blue Workspace" (each single quote is escaped with two single quotes).
- The SQL query parameter "Filter" uses JsonPath "$.value[*]".
- This gets JSON objects from "value" array and transforms them into SQL rows.

SQL Server

Use these SQL queries in SQL Server after you create a data source in Data Gateway:
