Looking for ServiceNow API Documentation for Scripting

[Nguyen Van Au]

helo every one
I am working on document integration with ServiceNow.
I am researching whether there is any API available to support coding for this.
Could you please provide me with the API documentation so that I can write scripts for it?
If there are any spelling mistakes, please help me correct them.
Thanks
