Auto-fill Hubspot Form Through API

[heyryanleys]

Hi,

I currently have a form that I created using HTML and CSS, and then linked to HubSpot through HubSpot's API. 

This is working great, but I am wondering if there is a way to auto-fill the form fields with known contact information, similar to how you can if you embed a HubSpot form using their JavaScript. 

Thanks for any help!

Hey @heyryanleys

Not too sure about API's but you can auto-populate HubSpot forms using Query Strings and Personalization Tokens. Not too sure if this is what you had in mind or needed.
