and then authorized with following scopes
a) oauth
b) timeline
c) contacts
d) automation
e) forms
authorized also got success with proper code
but the issue is, my app is not showing up under the integration’s in main hubspot account and checked in contact view as well there is no any sidebar created.
Even I have tried to generate token by using the above code but no luck.
Can you please let me know what is the issue on this?
That depends. Are you uploading the files to the file manager? Are you trying to attach the files to contact records? Are you trying to mimic the file attachment of HubSpot forms?
It's not possible to create a form that updates company properties. As a workaround, you could create a custom HTML form that submit to your server, and then use the companies API to mimic a companies form.
