How can I get read receipts from LinkedIn Voyager API? - linkedin

Question

I want to see if the last message has been seen by the person who I have sent the message to. I have got 20 conversation back from hitting this endpoint:
https://www.linkedin.com/voyager/api/messaging/conversations
I am using JSessions and cookies to authenticate. This is one of the conversations I got back:

Answer 1

Append conversationUrn to the link you are using.
I see that "entityUrn": "urn:li:fs_conversation:6408489350996336640"
In that case URL will be:
https://www.linkedin.com/voyager/api/messaging/conversations/6408489350996336640/events
It will return you the list of messages (events) from 1 specified above conversation with details of every message.
BTW, it's interesting that in your case conversationUrn is 6408489350996336640. Usually it looks like 2-MGQxMGNkMTctNGIxOS00N2RhLTgyMmUtNDE0MzAyYjI1ODRkXzAxMg==
