How to Execute Custom Code via an API Endpoint with Next.JS

anybody know if its possible to create like an API endpoint on Sanity to execute some custom code?
e.g. lets say i create a new component is "send an email" which needs to make an api call to a server-side function, can i make a endpoint which i can execute via a url?

e.g. in nextjs i can make

/pages/api/my-endpoint.js

Well, not directly on Sanity no, but you can have a webhook to an endpoint of yours.

so we'd need to run another web service to execute any custom code?

Hi , if you host your studio on e.g. Vercel or Netlify, you could add your serverless functions to an

/api

directory in your root folder and use them that way.
However, Sanity's hosted service (via

sanity deploy

to host on

<name>.sanity.studio

) does not offer support for lambdas at this point.

oh okay, thats handy to know - yeah we use vercel to host the cms.
would they run locally?

What does “they” stand for?

the serverless functions

The documentation linked by explains how to run them locally: https://vercel.com/docs/concepts/functions/serverless-functions#local-development
