I have a module that prompts the user with questions step by step and I want to save their answers in a hubdb table. Am I able to access the CMS API through a custom module using a javascript curl request? Or is their a better way to do it?

Hi, @AMastoris 👋 Thanks for your question.

I’d recommend looking into utilizing Serverless Functions if you have access. Or researching setting up some form of middleware. My main concerns with doing this client-side are:

- Security — you risk exposing your API or Private App keys by making calls client-side (from your module in this case) — [Include serverless functions in projects (BETA)](https://developers.hubspot.com/docs/platform/serverless-functions) and [Serverless functions](https://developers.hubspot.com/docs/cms/data/serverless-functions)
- CORS restrictions — HubSpot may block your cross-origin requests
- Rate limiting and performance — if multiple users are interacting with your application simultaneously, you may hit rate limits. Managing this server-side allows you more flexibility and control over how the calls are sent

Have fun building! — Jaycee
