How is this progressing? What are the main blockers?

[snarfed]

hey herb, glad you're interested! i'm not actively working on this. same with pretty much all open issues (mostly feature requests) without the "now" label.

for this one specifically, that's because i don't personally use linkedin. i'd love to have the support though! any interest in tackling it yourself?

[herbsmn]

I'd love to tackle this myself, but I am a super n00b and I probably would work on a different feature if I were to work on a feature of some sort. I didn't realize the "now" label meant you were working on it, but that's great to know. Keep up the great work! I use your service all the time.

if anyone's interested in tackling this, i've written up comprehensive instructions on how to add a new silo to bridgy. feel free to jump in!

I will take this on. @snarfed wrote great documentation. Then will need @dshanske help with the plugin.

I'd love to see this too. I've found myself (manually) POSSEing more of my content there lately, since I basically stopped using Facebook and there are now some people who are following me only on LinkedIn.

renewed interested in this on IRC today by @aaronpk.

so, bad news, probably. you can get comments, likes, etc from LI's Shares API (LI posts are called shares)...

...but most of their APIs, including that one, are limited to advertisers. the "Development" tier requires LinkedIn advertising related use case, and the "Basic" tier requires 30+ ads have been created by your app have passed LinkedIn’s editorial review.

here's how you apply. seems similar to Facebook's, wants lots of details about the app and how it works, but aimed at marketing and advertising specifically.

a few relevant SO q's:

• https://stackoverflow.com/questions/43584557/linkedin-v2-api-permission-for-reading-socialactions-and-shares
• https://stackoverflow.com/questions/48767510/linkedin-api-v2-endpoints-do-not-work
• https://stackoverflow.com/questions/46372629/why-does-linkedin-v2-share-api-give-not-enough-permissions-error-on-any-v2-share

another concern: the Shares API only lets me look at shares by "authorized members." i can't tell whether that means app owners, ie just myself, or anyone who's opted into my app. there's a decent chance it's the former.

sooo this is pretty unlikely, either via the API or scraping, since afaik you have to be logged in to see LI posts, and i'm definitely not going to ask bridgy users to give me their LI cookie or password.

sorry for the bad news. i'm open to other ideas!

[vandie]

Could this be approached using the browser extension like with Facebook and Instagram?

[snarfed]

Probably! But maintaining the scraping code for those two is a painful arms race, so I'm unlikely to do it myself. You're welcome to try if you want though! First step would be to add LI scraping support to granary.

Looks like the Share on LinkedIn consumer API could maybe now be used to do this.

[snarfed]

Interesting! Their docs do indeed sound like we could maybe do POSSE of posts, likes, and comments without an advertising account now. Promising!
