A method for facilitating transactions between tenants in a multi-tenant architecture system is discussed. The method includes receiving a request, at a multi-tenant platform, from a first service of a first tenant of the multi-tenant platform to access a second service of a second tenant of the multi-tenant platform to perform a transaction, in which the request includes a first access token usable to authenticate the transaction with the first tenant. The method includes generating, by the multi-tenant platform using the first access token, a universal access token. The method includes generating, by the multi-tenant platform using the universal access token, a second access token useable to authenticate the transaction with the second tenant. The method includes using, by the multi-tenant platform, the second access token to communicate with the second service to perform the transaction.
