Re: Threads testing federation via ActivityPub

Hi everyone,

Ben Savage here from Meta. Just a few quick points:


  1.  This test is not yet started (debugging some last technical issues together with Mastodon engineers)
  2.  Only a few accounts will be a part of this initial test. My Threads account (https://www.threads.net/@btsavage) will be one of those and I'm happy to make test posts to help people who want to work on Threads integration.
  3.  We will share details about how to test soon, once we iron these issues out.

--Ben

The page source does include application/activity+json: <link href="https: //www. threads. net/&#064;zuck/post/C0zXcQmxO77" type="application/activity+json" /> But curl doesn't work as you noted, perhaps it requires
ZjQcmQRYFpfptBannerStart
This Message Is From an Untrusted Sender

ZjQcmQRYFpfptBannerEnd

The page source does include application/activity+json: <link href="https://www.threads.net/<https://www.threads.net/>&#064;zuck/post/C0zXcQmxO77" type="application/activity+json" />

But curl doesn't work as you noted, perhaps it requires some additional things to limit it for internal test?

Mike Macgirving pointed out that I'm not using the right media type! I tried with ld+json and didn't get any traction, though.

curl -H 'Accept: application/ld+json; profile="https://www.w3.org/ns/activitystreams"<https://www.w3.org/ns/activitystreams>' https://www.threads.net/@zuck<https://www.threads.net/@zuck>

I just saw this post on Threads:

"Starting a test where posts from Threads accounts will be available on Mastodon and other services that use the ActivityPub protocol. Making Threads interoperable will give people more choice over how they interact and it will help content reach more people. I'm pretty optimistic about this."

I haven't been able to probe WebFinger for threads.net accounts, nor do Threads URLs reply with Activity Streams 2.0 content.

```
curl -H "Accept: application/activity+json" https://www.threads.net/@zuck<https://www.threads.net/@zuck>
curl -H "Accept: application/activity+json" https://www.threads.net/@zuck/post/C0zXcQmxO77<https://www.threads.net/@zuck/post/C0zXcQmxO77>
curl -v "https://www.threads.net/.well-known/webfinger?resource=acct:zuck@threads.net"<https://www.threads.net/.well-known/webfinger?resource=acct:zuck@threads.net>

```

Has anyone else been able to find signs of this "test" going on?
