Hi all,

Ive seen multiple threads explaining how to do this the other way around ie. from knack to another source but does anyone know how to add data into a form in knack from an external API?

I'm trying to design a vehicle lookup form with an external API but cant find anywhere that explains how to intergrate this.

Its a bit like an address lookup where you enter the zip code/postcode and submit and it pre populates the rest of the address.

Can anyone help please? I already have the API feed but no idea how to link it up.

Thanks all!

Would you consider using this [https://www.integromat.com/en/integrations/knack](https://www.integromat.com/en/integrations/knack)

I have just played around with it but it is pretty easy to implement

&nbsp;

There is an article here on how to use Zapier but pretty much the same thing to use Integromat

OR if you are a programer you could use this documentation
