Hello, this is Gulshan Negi.

Well, I searched about it on Google, and I found that integrating Facebook and Twitter in Odoo involves installing the Social Media Integration module, configuring the Facebook App ID and App Secret and Twitter Consumer Key and Consumer Secret in the Social Media Integration settings, and using Odoo's social media integration features to create and schedule posts on your social media accounts. Depending on your specific requirements and the version of Odoo you are using, additional steps or customization may be necessary.

Thanks
