Api call with auth (oauth)

I am trying to create an integration with Brightidea API.
But before make the call this api need oauth with username, password, secret…

I have tried everything but i cant make it work. Could you please exmplain me how i should create this oauth??

Have you tried testing it in postman or insomnia yet? If so and it works, then transfer it to Wappler. I would always recommend testing in either of these tools first. Porting afterwards is generally very straightforward
