Connecting to MS Office 365 Graph API through  on-premise SSIS

There is no inbuilt connector to call OAuth API in SSIS (e.g. Graph API using OAuth). However if you are open for trying 3rd party connectors then check out ZappySys JSON Source and OAuth Connection. Basically on OAuth Connection just set like below
1) Version=OAuth2
2) Grant Type=Client Credentials
3) Token URL=https://login.microsoftonline.com/<Tenant Id>/oauth2/token
4) On Advanced Tab Enter extra attributes for Token URL as below
resource=https://graph.microsoft.com
5) Save connection
Thats it ... after that you can use OAuth Connection in components like JSON Source, Web API Destination and so on... if you use JSON Source set Format as OData so pagination is taken care too.

For using 3-legged OAuth you can try something like below
