Neo then reaches every customer card of that account. ## 1. Get your API interface **1. Open the Grexx portal** Sign in to the Grexx portal of your RoutIT or KPN account. If you have no API access yet, ask your RoutIT or KPN account manager for an API user. **2. Copy the webservice URL** Open the **API Toolbox** and the interface's **API gegevens**. Copy the webservice URL, such as `https://service.grexx.today/interfaces/routit//`. A URL that ends in `/realtime` is fine: Neo removes it. **3. Copy the API user** Copy the API user name. Grexx emails the password, or your account manager gives it to you. ## 2. Whitelist Neo Grexx answers only addresses that are whitelisted for the interface. Add all of [Neo's IP addresses](https://docs.neoagent.io/integrations/ip-whitelisting.md) to the interface in the Grexx portal, or ask Grexx to add them. Neo's customer mapping and seat changes need the customer and order messages on the interface: ask RoutIT or KPN to allow them if they are not. ## 3. Add the login in Neo **1. Open Integrations** In the Neo Dashboard, open **Integrations** and find the RoutIT / KPN card, under Cloud Marketplace. **2. Save the login** Paste the webservice URL, pick the sign-in method, enter the API user name and password, and click **Save settings**. Grexx interfaces take either **Basic authentication** or an **OAuth 2.0 token**. If you are not sure which yours takes, pick one: Neo reads one customer card before saving, and when the method you picked is refused and the other works, the message tells you to pick the other. > [!WARNING] > > If the API user's password changes in Grexx, Neo loses access until you save the new one here. ## 4. Check the customer mapping Neo matches each customer card to a PSA company by name. Open the RoutIT / KPN card's **Organization Mapping** tab to correct a match, confirm a suggested one, or map a company by hand. ## 5. Turn on seat changes Add **Change License Seats** and **List License Subscriptions** to your onboarding and offboarding agents. In Change License Seats, turn on **Require technician approval** if a technician should confirm each seat change. Ask your Neo Support Agent to set this up: for example, "When someone joins, ask the technician which licence to add and add the seat on RoutIT; when someone leaves, remove the seat." A seat change on RoutIT / KPN applies now. To lower seats at a licence's renewal, schedule the agent to run on the renewal day. ## 6. Turn the RoutIT / KPN API on per agent For everything beyond seat counts, open the agent, go to its **Tools & Settings** tab, click **Cloud Marketplace**, and expand the **RoutIT / KPN** block. Pick one of its **Presets**, or set each area yourself: | Area | Access levels you can pick | Notes | | - | - | - | | **Customers and Contacts** | Disabled, Read Only, Read / Write | Customer cards and their contacts. | | **Orders and Licences** | Disabled, Read Only, Read / Write | Orders with their quantities, new licence, add-on, Teams and upgrade orders, labels and terminations.
