Title: Meta offers an OAuth based API for Instagram.
Many companies and tools are built on and rely on this API for their product &amp; daily operations.<p>Beginning Friday evening (US time), a critical endpoint in this API has broken. The endpoint creates long-lived access tokens, so it is in the critical path for almost any company using the API.<p>I find it disappointing that a leading technological company does not acknowledge a bug that&#x27;s been reported to them several times more than 24 hours ago, even if to say that&#x27;s it&#x27;s being investigated.<p>The endpoint: 
https:&#x2F;&#x2F;developers.facebook.com&#x2F;docs&#x2F;instagram-basic-display-api&#x2F;guides&#x2F;long-lived-access-tokens#get-a-long-lived-token<p>Currently the API returns a Bad Request with a wrong error message (the endpoint should support &quot;GET&quot;):
```
{
  &quot;message&quot;: &quot;Unsupported request - method type: get&quot;,
  &quot;type&quot;: &quot;IGApiException&quot;,
  &quot;code&quot;: 100,
  &quot;fbtrace_id&quot;: &quot;AuDYqK74IrT9Yt2Sx51UlP6&quot;
}
```<p>I have opened a bug report but received no response.
Facebook&#x27;s status page shows all green in the API section: https:&#x2F;&#x2F;metastatus.com&#x2F;
There are several Meta Developers Community threads with no response
