Do you want to have Manychat reply to your inbox messages in LinkedIn?

Yeah, you won’t be able to do that unfortunately :(

Has the above been addressed or is it still not possible to use ManyChat with LinkedIn? 

Still not possible, as far as I know LinkedIn does not have a conversations API.

Hi ​@Gustavo Boregio . Any news about this? LinkedIn DOES offer now an API for LinkedIn messaging. https://www.linkedin.com/help/linkedin/answer/a6246714
