I am very new to integration part.
I need to do one requirement. I have one Custom Object in which I am storing data. Now I want to expose this data to the external system. For this, as I know I need to create the API and expose it to the external system. but I am totally clueless about this.
I have done it through Postman, I am able to get the access token and fetch the data, but how can I convert it to the code. Please help!
Can you guys please send me the steps that can follow to achieve this scenario.
Thanks in advance Nirav
