External Identifiers

We allow you to use your existing identifiers of key entities to refer to the same entities within our system. This reduces the integration burden for you, as you do not need to manage and track Rail identifiers against the same entities in your system

We call these External Identifiers. In general, this model was put into place to reduce your integration efforts and complexity, and have you up and running faster and more efficiently. Currently we define external identifiers for

• Customer Identifiers
• Account Identifiers

Where external identifiers are used, you do not need to be concerned about clashes with other Rail clients as we ensure uniqueness at the client level.
