Hi All,

@RintoIgnatious

You can customize the form to include an onFormSubmit callback. Here is a [link to the documentation](https://legacydocs.hubspot.com/docs/methods/forms/advanced_form_options)

Another option (possibly better) would be to create a workflow with a [custom coded action](https://knowledge.hubspot.com/workflows/use-custom-code-actions-in-workflows) that would triggered on submit. This does require Operations Hub professional tier, though.

@Bryantworks might have a better suggestion 😀

Hi @RintoIgnatious ,

Try to use ajax or serverless functions to make external api-call .To get more info about serverless functions refer to this doc [https://developers.hubspot.com/docs/cms/data/serverless-functions.](https://developers.hubspot.com/docs/cms/data/serverless-functions)

Hope this helps!
