I am configuring an implementation in Azure whereby I will perform a GET request to the order API on a timer to recieve new orders placed in the webshop. Azure Logic app doesn’t support oAuth 1.0 native so I am having to create an Azure function for this.

I am using C# and struggling to create the oauth_signature. I have successfully created the nonce and timestamp but this one piece of the puzzle stumps me. Happy to use another language such as PHP.

I have followed the oAuth documentation at https://oauth.net/core/1.0/ however I am unable to generate a successful signature.

Does anyone have any experience with this or any steps to generate this signature successfully?

when querying the API in postman, it generates the timestamp, nonce and signature on the fly which I cannot do with Azure function.

Thanks
