Some of Terminal’s endpoints feature an expand parameter that allows you to expand nested resources. This helps you get straight to the data you’re looking for in less requests.

​
Example

As an example, if you are calling an expandable endpoint that includes the following relationship: 
{
  "vehicle": "vcl_01GSKTHKXVVS2EKE6MP0N20YPE"
}
By providing expand=vehicle in the request you can expand the field to include all details: 
{
  "vehicle": {
    "id": "vcl_01GSKTHKXVVS2EKE6MP0N20YPE",
    "vin": "12345"
    // ... other vehicle properties
  }
}
