Logic App - Yammer connection error

Question

Hi,

When trying to create a connection from LogicApp to Yammer (with 3rd party app enabled in Yammer) I get the following message:

Failed with error: 'OAuth2 authorization flow failed for service 'Yammer'. OAuth 2 sign in failed to exchange code for access token. Client ID and secret sent in form body.. Response status code=Forbidden. Response body: Your network is not allowed to request an OAuth token for this Application Client ID and secret sent in Basic authorization header.. Response status code=NotFound. Response body: invalid client application '. Please sign in again.

Some posts indicates that it has been resolved (https://github.com/MicrosoftDocs/OfficeDocs-O365ITPro/issues/290) but I'm still experiencing this issue.
Maybe I missed a configuration somewhere ?

Thanks

Answer 1

It seems that when the Logic app is not in the same region as yammer (In the US I guess ?), the authentication fails.

Here are my tests:

Logic app in Canada Central -> Authentication fails with the previous message
Logic app in East US -> Authentication Successful.

Is it a configuration that I have to do to allow Yammer to communicate with a logic app in a different region ?
Is this even possible ?

Thanks

@Anonymous Yammer connector works only with corporate tenants. data-residency document might help you in this. It says

When you enroll from Europe or Africa your network is associated with the EU Geo and when you enroll from Australia, Asia, North America, or South America your network is associated with the US Geo.

However, I am discussing this with the product group on the "same region" part. I will share the updates at the earliest.
