Hi Mates,

We had a cloud environment configured for our client.  we are using the K2 Dev integration account to authenticate with K2. 

To test the workflow Rest api. I had used the postman. In Postman we are trying to retrieve the list of all workflows. Using my id it's working fine. but when I used K2 Dev integration account (*personal details removed*). I am getting below error 

"Message": "Authorization has been denied for this request.".

I am using the Basic Authentication mode to call the workflow API from Postman. will it work? K2 Dev integration account has global administrator permission on AAD. I have granted Admin, Export & impersonate rights server rights to this account. 

 

Can you please let me know what permission is required? how it can be works

Hi,
Thanks for your reply. Can we have APP to APP authentication? What kind of rights and configuration is required to set up that?

Hi  @Tan ;


 


As per this kb (https://help.k2.com/kb002838) you need to add the K2 delegated API permission to your Azure AD App, as it's necessary for K2 to authorize the OAuth request from your AAD identity.

Good day Tan


In addition to the information that “Widson” has provided I believe that you will need to make use of Inbound OAuth which means 'incoming' integration where third-party systems need to interact with K2 APIs. Examples include custom applications that need to start workflows, retrieve and complete workflow tasks, or execute SmartObject methods via K2 APIs. In this scenario, the bearer token is verified and used by K2 to authorize the incoming request. These incoming tokens are not cached by K2. This article describes how to set up and use inbound OAuth.


 


Please see the following KB article which describes how to Configure AAD and K2 Services for Inbound OAuth: https://help.k2.com/kb002784


 


Kind regards,
