SharePoint Online Service Now Integration

[Kannan16]

I'm new to Service Now Developer Community. I have a requirement to Display Knowledge Base Articles / Incidents in SharePoint Online from Service Now. 

I have the following requirements.

1) KB Article is managed in Service Now but end users will view the article in SharePoint.

2) Users will log Incidents from SharePoint and that information should be routed to Service Now.

3) Users should be able to Search SNOW content from SP.

Could someone let me know what are the integration capabilities available in SNOW to achieve this? There are couple of architecture options

1) Sync data between both system using a connector (for ex., a tool like SYNQ) so that view/search article is bit easy to manage.

2) Use SNOW REST API capabilities and display content dynamically in SP.

I'm like Option 1 but drawback is content is duplicated in SP. Not sure if this a good pattern but there are some products which cater to this scenario.SYNQ

What should I consider if I go with Option 2? What are the pros/cons of Service now REST API.

Could someone point me the right direction?

This is searching content from Service Now to an external system. Are there any samples for consuming Service Now from SharePoint Online?
