# Deprecations

> Deprecated features in the Junction Lab Testing API, including the lab_test_id field replaced by order_set in order creation.

### `lab_test_id` in the [POST /v3/order](/api-reference/lab-testing/create-order) endpoint.

`lab_test_id` is deprecated in favor of the `order_set` field. More information [here](/lab/workflow/ordering).

<Steps>
  <Step title="Remove lab_test_id usage" stepNumber="1" titleSize="p">
    In the `order` payload, remove the usage of `lab_test_id`

    ```json theme={null}
    {
        "lab_test_id": "some_id" # Remove this
    }
    ```
  </Step>

  <Step title="Use the order_set field" stepNumber="2" titleSize="p">
    In the `order` payload, add the `order_set` object.

    ```json theme={null}
    {
        "order_set": {
            "lab_test_ids": ["some_id"]
        }
    }
    ```
  </Step>
</Steps>

### `value` field in the `results` object

We are removing the `value` field from the [results object](/api-reference/lab-testing/results/get-results), as it does not accurately capture all possible result values. In turn, we've introduced the `result` field.

<Card title="Recommended Action">
  Parse the `result` field in accordance with the `result_type` field. [More information here](/lab/results/result-formats#resulttype).
</Card>

### `requisition_form_url` in the `order` object

This field is a signed GCP bucket URL, which is only active for 7 days. It will be removed in favor of the [download PDF](/api-reference/lab-testing/requisition-pdf) endpoint.

### `GET /v3/lab_tests` in favor of `GET /v3/lab_test`

The endpoint `GET /v3/lab_tests` is deprecated in favor of `GET /v3/lab_test`. The new endpoint will return a paginated list of lab tests and supports two new parameters: `lab_test_limit` and `next_cursor`.
