# Configuring the API Communication

When installing or upgrading QA Inspector, the application runs an automatic check to determine whether the API communication must be enabled by default:

- If QA Inspector detects previous connections to external systems or applications via API, the API communication is enabled by default. This is the case of QA Inspector upgrades in which the database of the previous version is kept through the upgrade.

- If QA Inspector does not detect previous connections to external systems or applications via API, the API communication is disabled by default. This is the case of QA Inspector first installations, or of QA Inspector upgrades in which the database of the previous version has been deleted.

1. On the home menu, tap Configuration > External systems > API.

2. On the General tab, select Enabled.

3. Enter the API Port in the text field (default value: 60005; value range: 1 - 65535).

4. On the top bar, tap Apply .
