Post Request API with SQL Server - sql

Question

I wanted to create a stored procedure in SQL Server to complete a POST request. The request would take two parameters.
Curl that I've used for Postman:
curl -X 'POST' \
'https://link' \
-H 'accept: application/json' \
-H 'Authorization: Bearer somepassword' \
-H 'Content-Type: application/json' \
-d '{
"userName": "username",
"password": "password"
}'
I've tried writing the code below, but it doesn't seem to work...
DECLARE #token INT;
DECLARE #ret INT;
DECLARE #url NVARCHAR(MAX);
DECLARE #apiKey NVARCHAR(32);
DECLARE #json AS TABLE(Json_Table NVARCHAR(MAX))
DECLARE #userName varchar(max)
DECLARE #password varchar(max)
DECLARE #body varchar(max)
SET #url = 'https://link'
SET #userName = 'username'
SET #password = 'password'
SET #body = '
{
"userName": "'+#username+'",
"password": "'+#password+'"
}
'
EXEC #ret = sp_OACreate 'MSXML2.XMLHTTP', #token OUT;
IF #ret <> 0
RAISERROR('Unable to open HTTP connection.', 10, 1);
-- This calls the necessary methods.
EXEC #ret = sp_OAMethod #token, 'open', NULL, 'GET', #url, 'false';
EXEC #ret = sp_OAMethod #token, 'send', null, #body
-- Grab the responseText property, and insert the JSON string into a table temporarily. This is very important, if you don't do this step you'll run into problems.
INSERT INTO #json (Json_Table)
EXEC sp_OAGetProperty #token, 'responseText'
-- This is all I have to add to insert into a non-existing table.
SELECT *
FROM OPENJSON((SELECT * FROM #json))

I recommend against using the legacy, hard-to-use OA procedures. Instead, this is a task for a .NET library via SQLCLR. For years I have used this library to handle API calls from the database.
