Demonstrates how to send an HTTP request with SQL Server using OLE Automation.

EXEC sp_configure 'Ole Automation Procedures', 1;

Send_HTTP_Request.sql

DECLARE @authHeader NVARCHAR(64);
DECLARE @contentType NVARCHAR(64);
DECLARE @postData NVARCHAR(2000);
DECLARE @responseText NVARCHAR(2000);
DECLARE @responseXML NVARCHAR(2000);
DECLARE @ret INT;
DECLARE @status NVARCHAR(32);
DECLARE @statusText NVARCHAR(32);
DECLARE @token INT;
DECLARE @url NVARCHAR(256);

SET @authHeader = 'BASIC 0123456789ABCDEF0123456789ABCDEF';
SET @contentType = 'application/x-www-form-urlencoded';
SET @postData = 'value1=Hello&value2=World';
SET @url = 'https://en43ylz3txlaz.x.pipedream.net';

-- Open the connection.
EXEC @ret = sp_OACreate 'MSXML2.ServerXMLHTTP', @token OUT;
IF @ret <> 0 RAISERROR('Unable to open HTTP connection.', 10, 1);

-- Send the request.
EXEC @ret = sp_OAMethod @token, 'open', NULL, 'POST', @url, 'false';
EXEC @ret = sp_OAMethod @token, 'setRequestHeader', NULL, 'Authentication', @authHeader;
EXEC @ret = sp_OAMethod @token, 'setRequestHeader', NULL, 'Content-type', @contentType;
EXEC @ret = sp_OAMethod @token, 'send', NULL, @postData;

-- Handle the response.
EXEC @ret = sp_OAGetProperty @token, 'status', @status OUT;
EXEC @ret = sp_OAGetProperty @token, 'statusText', @statusText OUT;
EXEC @ret = sp_OAGetProperty @token, 'responseText', @responseText OUT;

-- Show the response.
PRINT 'Status: ' + @status + ' (' + @statusText + ')';
PRINT 'Response text: ' + @responseText;

-- Close the connection.
EXEC @ret = sp_OADestroy @token;
IF @ret <> 0 RAISERROR('Unable to close HTTP connection.', 10, 1);

there should be an example for reading response headers. ie.

DECLARE @header NVARCHAR; 
EXEC @ret = sp_OAMethod @token, 'getResponseHeader', @header OUTPUT, 'Headername'; 

not work for me ! why !? how can i debug it ?

Not sure if this is still an issue, but

DECLARE @key NVARCHAR(100) = [GUID/KEY]; DECLARE @authHeader = ['Bearer/Basic'] + @key; EXEC @ret = sp_OAMethod @token, 'setRequestHeader', NULL, 'Authorization', @authHeader;

How should I post data using body and GET method?

I am trying this code

EXEC @ret = sp_OAMethod @token, 'open', NULL, 'GET', @url, 'false';
EXEC @ret = sp_OAMethod @token, 'setRequestHeader', NULL, 'wts-session', @apiSession;
EXEC @ret = sp_OAMethod @token, 'setRequestHeader', NULL, 'wts-licencetype', @licencetype;
EXEC @ret = sp_OAMethod @token, 'setRequestHeader', NULL, 'Content-type', @contentType;
EXEC @ret = sp_OAMethod @token, 'send', NULL, @Body

Hі!

Can you please help correctly compose multipart/form-data request?

Thks

Hi
The post request does not work for sql server 2008.
Any reason ?

What if the passed value is in HTTP body and not attached to URL ? Consider the data in the body to be in JSON format.
