# Phlebotomy Service Tiers

> Compare the two phlebotomy service tiers: Appointment Ready for synchronous scheduling and Appointment Request for asynchronous assignment.

Junction offers multiple Tiers of phlebotomy services, with different coverage capabilities:

* **Appointment Ready:** An appointment is booked in Junction using the patient's address and the appointment's date and time. The scheduling is completely synchronous and fully controlled by Junction's customers through our API.
* **Appointment Request:** An appointment is requested through the Junction system using the patient's address. A phlebotomist will eventually assign themselves to the appointment and define the appointment's date and time with the patient.

The following Providers are available for each Tier:

|                     | Getlabs | Phlebfinders (Beta) |
| :------------------ | :-----: | :-----------------: |
| Appointment Ready   |    X    |                     |
| Appointment Request |         |          X          |

<Info>`appointment-request` appointments will start in the `pending` status, and won't have any time or date information.</Info>

## High Level flow for Appointment Scheduling

The recommended high-level flow for selecting an appointment at Junction is:

* Place an At-Home Phlebotomy order with the [`POST /v3/order`](/api-reference/lab-testing/create-order) endpoint.
* Wait for the `Requisition Ready` status updates through our Webhooks.
* Fetch Provider data via the [`GET /v3/order/area/info`](/api-reference/lab-testing/area-info) endpoint, the response payload should look like this:

```json theme={null}
{
  "zip_code": "85004",
  "phlebotomy": {
    "is_served": true,
    "providers": [
      {
        "name": "getlabs",
        "tier": ["appointment-ready"]
      },
      {
        "name": "phlebfinders",
        "tier": ["appointment-request"]
      }
    ]
  }
}
```

* Select the Provider that best fits your needs.
  * If you use the [`POST /v3/order/{order_id}/phlebotomy/appointment/book`](/api-reference/lab-testing-at-home-phlebotomy/appointment-booking) endpoint, an `appointment-ready` provider is chosen on your behalf.
  * If you use the [`POST /v3/order/{order_id}/phlebotomy/appointment/request`](/api-reference/lab-testing-at-home-phlebotomy/appointment-request) endpoint, you must select a provider that offers an `appointment-request` tier.
* Wait for the `Appointment Webhooks` and `Order Webhooks` described in the [Webhooks](/lab/at-home-phlebotomy/webhooks) section.
