/// tip | 豆知識

使用されるコールバック URL には、クエリパラメータ `callback_url`（`https://www.external.org/events`）で受け取った URL と、JSON ボディ内の請求書 `id`（`2expen51ve`）が含まれている点に注目してください。

### コールバック用ルーターを追加 { #add-the-callback-router }

これで、上で作成したコールバック用ルーター内に、必要なコールバックの *path operation(s)*（*外部開発者* が *外部 API* に実装すべきもの）が用意できました。

次に、*あなたの API の path operation デコレータ*の `callbacks` パラメータに、そのコールバック用ルーターの属性 `.routes`（実体はルート/*path operations* の `list`）を渡します:

    checkNotNull(target, "target");
    if (target.length == 0) {
      return 0;
    }

    outer:
    for (int i = 0; i < array.length - target.length + 1; i++) {
      for (int j = 0; j < target.length; j++) {
        if (array[i + j] != target[j]) {
          continue outer;
        }
      }
      return i;
    }
    return -1;
  }

  /**

        assertNull(crawlingConfigHelper.getCrawlingConfig("W123"));
    }

    @Test
    public void test_store_counterIncrement() {
        final String sessionId = "testSession";

        // Test counter increment
        String sessionCountId1 = crawlingConfigHelper.store(sessionId, crawlingConfigHelper.getCrawlingConfig("W1"));
        assertEquals("testSession-1", sessionCountId1);

	DB.Select("users.*, user_speaks.*,  languages.*, pets.*").Table("users").Joins("JOIN user_speaks ON user_speaks.user_id = users.id").
		Joins("JOIN languages ON languages.code = user_speaks.language_code").
		Joins("LEFT OUTER JOIN pets ON pets.user_id = users.id").Find(&results)

	if len(results) == 0 {
		t.Fatalf("no record find")
	} else if results[0].Pet.UserID == nil || *(results[0].Pet.UserID) != user.ID {

    checkNotNull(target, "target");
    if (target.length == 0) {
      return 0;
    }

    outer:
    for (int i = 0; i < array.length - target.length + 1; i++) {
      for (int j = 0; j < target.length; j++) {
        if (array[i + j] != target[j]) {
          continue outer;
        }
      }
      return i;
    }
    return -1;
  }
