Hi Rohit,
Thank you for reaching out to our team.
Please note that App Scripts is outside of our expertise already so I would not be able to assist you on generating API requests using it. However, if you will be directly using CURL, then I would suggest referring to this
document as it presents details specific to REST and explains what you need to know to call the REST interface directly. Then, refer to this
document to know how to construct the body of the API request for generating historical metrics. Lastly, refer to this
document so that you can apply the procedure discussed there in the REST interface for generating historical metrics.
Let me know if you have questions with the provided support.
Regards,
