I need to create an API, that will get the body fields, do some calculations (including calling another API), and return a response with some data in the body.
Is this something I can achieve and if so, which Zap should I use?

Hi there
Welcome to the Community! 
This could be possible, you can use a combination of Webhooks by Zapier and Code by Zapier in your Zap. Please keep in mind that this is an advanced feature, so our support for it may be more limited. But, we are always happy to help!
To see if your question has already been asked, you can check out the questions that have already been answered in the Code by Zapier and Webhooks by Zapier section of our Community: https://community.zapier.com/code-webhooks-52

Hopefully, this helps! 
Thanks, Ken.
As I understand, from the responses I found, I cannot change the default response of the webhook. Does Zapier have an API connector I can expose and create the code behind?
