# Identifying the Instance

**Authorization**: administration token

**Endpoint information**: [Get a list of instances](/apis/openapispec/instances/listinstances)

The instance whose short name contains "def-inst"—for example, ACME-def-inst, where ACME is the customer name—is always the instance used for auto-provisioning line items to Elastic Access.

Producers should send a GET call to **/provisioning/api/v1.0/instances** to identify the Elastic Access instances which host the line items belonging to customers.

| Item | Description |
|  --- | --- |
| **URI** | **/provisioning/api/v1.0/instances** |
| **Method** | GET |
| **Query parameters** | `next`, `size` |
| **Request body** | N/A |
