getting a "could not authenticate you."
I want to use the API and i'm completely new to it.
I have tried every thing i found on the tutorials and documentations available on the support site and i am not able to simply retrieve the shop information.
I have my api_key and api_secret and i'm using the Postman collection that i took here (https://developers.lightspeedhq.com/ecom/introduction/postman/).
I only get this response which is pretty clear but i am not able to find a way to correct this.
"message": "Could not authenticate you."
it's probably a little dumb error i made or something i didn't make but help will be greatly appreciated !
thanks in advance !
