How to send http POST request from sql server stored procedure. Important! For some reason sp_OAGetProperty is returning null. Am not sure why and if anyone has an idea can update the gists. In case you need to try another option SQL CLR would help. Check here https://gist.github.com/JahsonKim/05e6af7744f2d7ef814e5ed331419db5

Hi @JahsonKim, thanks for replying, I'm accessing it from my local machine.

Use http instead of https for localhost

Hi @JahsonKim, using http worked!
Thank you so much. :)

Hi @JahsonKim
how we can take OAUth2 Token at this way?
In fact, I need to get Json Bearer Token output by running this SP

Hii
One example use in Triggers Insert or Update

ALTER TRIGGER [dbo].[my_test]
ON [dbo].[webhook_logs]
WITH EXECUTE AS CALLER
AFTER INSERT, UPDATE
AS
BEGIN

	SET NOCOUNT ON
	
	DECLARE @id INT
	DECLARE @procesado INT = 0
	DECLARE @urlBase VARCHAR(8000) = 'http://192.168.0.2:8080/' -- Local use or Best security use HTTPS://
	DECLARE @jsonBody VARCHAR(8000) = ''
	DECLARE @jsonReps VARCHAR(8000) = ''

	SELECT @id = I.id, @procesado = I.procesado, @jsonBody = I.json FROM inserted I

	-- Change
	IF (SELECT @jsonBody)<>'' AND @procesado=0
	BEGIN 

		SELECT @jsonReps = dbo.my_function_post_json(@urlBase+'controller/post.json', @jsonBody);

		IF CHARINDEX('"ok":true', @jsonReps)>0
		BEGIN
				-- IS INSERT..?
				IF EXISTS(SELECT 1 FROM inserted) AND NOT EXISTS(SELECT 1 FROM deleted)  
				BEGIN
					UPDATE [dbo].[tableX] SET
								[field1] = 1,
								[field2] = GETDATE(),
								[field3] = GETDATE() 
					WHERE [id] = @id 
				END
				ELSE
				BEGIN
					UPDATE [dbo].[tableX] SET
								[field1] = 1,
								[field2] = GETDATE() 
					WHERE [id] = @id 
				END
		
		END
		
	END

END

@JahsonKim Good morning everyone, your publication is great but I would like to know how you send a cookie in the post request, such as authorization headers since in a project I ran into this problem and it does not return the data that is in json, someone who has idea of how to keep that session cookie until the client is closed,
that if I am performing a stored procedure with that requirement

Thank you very much in advance, I look forward to your answers

Three years later, you're still helping people! Thanks so much for this.

Yes! Still very useful! Thank you!

I've triyng to use like the example above, here's my code to give a post:

DECLARE @object int;
DECLARE @url varchar(8000);
DECLARE @token varchar(1000);
DECLARE @headers varchar(8000);
DECLARE @body varchar(8000);
DECLARE @response varchar(8000);

-- Define o endpoint da stored procedure
SET @url = 'https://api.openai.com/v1/completions';

-- Define o token de autenticação
SET @token = 'Bearer openIAToken';

-- Define o cabeçalho da requisição com o token de autenticação e o tipo de conteúdo JSON
SET @headers = 'Authorization: ' + @token + char(13) + char(10)
  + 'Content-Type: application/json' + char(13) + char(10);

-- Define o corpo da mensagem no formato JSON
SET @body = '{"model": "text-davinci-001", "prompt": "What gifts should I buy for Christmas?", "max_tokens": 64, "temperature": 0.5}';

-- Cria o objeto de conexão HTTP
EXEC sp_OACreate 'MSXML2.XMLHTTP', @object OUT;

-- Envia a requisição POST com o corpo da mensagem no formato JSON
EXEC sp_OAMethod @object, 'open', NULL, 'POST', @url, false;
EXEC sp_OAMethod @object, 'setRequestHeader', NULL, @headers;
EXEC sp_OAMethod @object, 'send', NULL, @body;

-- Obtém a resposta da requisição
EXEC sp_OAMethod @object, 'responseText', @response OUTPUT;

-- Imprime a resposta
PRINT @response;

-- Libera o objeto de conexão HTTP
EXEC sp_OADestroy @object;

But the response is always empty. Any ideias on how may be causing this empty response?

❗UPDATE❗
Here is my solution to call all kind methods inside ``Sql Server`

Olá Jose, tudo bem?

Estou com o mesmo problema. O meu response sempre vem vazio. Você conseguiu achar uma solução ou correção do código?

Grato!

Oi, @rickheber... td certo?

Consegui encontrar uma solução sim, inclusive fui um pouco mais além, montei os metodos de GET e PUT.
ô, vale resaltar que o uso do metodo de interação com json, como por exemplo o JSON_VALUE, somente estão disponíveis a partir da versão 2016 do SQL Server.

Mas se voce possuir um versão inferior, pode tentar verificar se a mesma possui compatibilidade com esses metodos,

SELECT compatibility_level
FROM sys.databases
WHERE name = 'DataBaseName';

Caso o retorno seja um valor igual ou superior a 130 (default para versão 2016), significa que é compatível, portanto não precisa fazer a atualização da versão!

Eu postei as procedures em meu GitHuib pessoal, no serviço do gist, voce pode acessar elas por aqui.

Outra coisa, antes rodar as procedures, você precisa ativar as configurações de conexão externa do SQL Server, basta rodar o comando abaixo:

sp_configure 'show advanced options', 1;
GO
     RECONFIGURE;
GO
sp_configure 'Ole Automation Procedures', 1;
GO
    RECONFIGURE;
GO

• Caso elas não estejam ativas, as procedures não funcionaram!!
  Qualquer duvida, pode abrir uma nova discussão!!

Not working with SQLServer 2008. Could you help update this?

Sql Server 2008 probabily do not suport this methods, try run this comand in you Sql Server, before run the procedure:

sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ole Automation Procedures', 1;
GO
RECONFIGURE;
GO

This basic allows you to use the methods to call external services in Sql Server.

If that do not help, try see in the link this forum about compatibility ⬇
-- See about compatibility level here

Oi José....

Cara, muito obrigado pelo seu rapido retorno! Eu vou dar uma olhada na sua publicação agora mesmo!

Por enquanto, muito obrigado por compartilhar o seu conhecimento!

Abraços

Abraço, @rickheber 🤠🤙

@JahsonKim

If the data to post is not querystring mode, it is json structure writing, how to adjust this?

Thanks
Eric Xin

For some reason sp_OAGetProperty is returning null.

Am not sure why and if anyone has an idea can update the gists.
In case you are looking for an alternative to making http requests from the database, you can try SQL CLR.
Check here on how to implement SQL CLR

@ericxin1982 If you sent the post data as json string I think it will processed by the API. Ensure you also set the content type as application/json. If this doesn't work maybe you can use SQL CLR which is more flexible.
