Send generated values in test as parameters to fixture in pytest

Let me give you and idea of what the test is about.
In this test, I'm calling an API that basically generates a file and an item in a DynamoDB table. The response the service, gives me the UUID that I use to look into the DB and check that everything is created correctly.
However, I cannot do the teardown in fixture because the uuid I need to delete item in dynamo is generated in the test. Right now, I'm deleting the item in the test but I wanted to do it in the fixture but I'm not sure if its possible to pass this uuid to the fixture.
Any suggestions or ideas?

@pytest.fixture
def prepare_test(self):
    body = open(self._filepath, "r")
    yield body
def test_post_template_tyc_happy_path(self, prepare_test):
    body = prepare_test
    response_body = self._tyc_api.post_template_contract(body.read(), header, 'LOAN', 'GOBIERNO', 'AUTOMATED_QA_TEST')
    result_dynamo = self._tyc_crud.find_contract_by_product_id_and_tac_version_id_async(response_body['productId'], response_body['tacVersionId'])
    assert response_body['productId'] == 'LOAN'
    assert response_body['tacVersionId'][:-36] == 'GOBIERNO#'
    assert response_body['description'] == 'AUTOMATED_QA_TEST'
    assert response_body['isLastVersion'] is True
    assert result_dynamo.description == 'AUTOMATED_QA_TEST'
    assert result_dynamo.tac_id == 'GOBIERNO'
    self.delete_test_data(response_body['productId'], response_body['tacVersionId'])
def delete_test_data(self, product_id, tac_version_id):
    self._tyc_crud.delete_contract_by_product_id_and_tac_version_id(product_id, tac_version_id)

Thanks!
