# Connect GLS Denmark

> Connect GLS Denmark from Carriers → All Carriers — Login Name, Password, Customer ID, Contact ID, and optional Sandbox Mode.

**GLS Denmark** books Danish and European parcel labels from Zippendo: business, private home, ParcelShop, express, returns, and pick services. The catalog card copy is: **Create GLS Denmark labels in Zippendo for business, private, and ParcelShop deliveries across Denmark and Europe.** Catalog slug: `gls_dk`.

This page is the GLS connect form. Shared chrome: [Carrier credentials](/docs/how-to/carrier-credentials). Inventory: [Connect a carrier or integration](/docs/how-to/connect-index). Walkthrough: [Carriers](/docs/tutorials/carriers).

<Info>
  You do **not** pick a sender address on this form. Add addresses under **Manage → Addresses**. The address is chosen on the shipment or on a [shipping rule](/docs/how-to/shipping-rule-fields).
</Info>

## Prerequisites

* A **GLS Denmark** shipping agreement. Zippendo’s GLS integration is the Denmark Label API (`gls_dk`), not GLS in another country.
* Four values GLS issues with that agreement: **Login Name**, **Password**, **Customer ID**, and **Contact ID**. There is no self-serve API-key screen in Zippendo. **Learn more** opens [gls-group.eu/DK](https://gls-group.eu/DK).
* Permission to create carriers in the organization. Connecting another GLS account is allowed if each connection has its own **Carrier name**.

## Connect from All Carriers

<Steps>
  <Step title="Open All Carriers">
    Sidebar **Carriers**. Page title **Carriers / Integrations**. Header tabs: **My Carriers** (`?tab=my-carriers`) and **All Carriers** (`?tab=all-carriers`).
  </Step>

  <Step title="Find GLS Denmark">
    The card title is **GLS Denmark**. Buttons: **Connect** and **Learn more** (opens [gls-group.eu/DK](https://gls-group.eu/DK) in a new tab).
  </Step>

  <Step title="Click Connect">
    Modal id `connect-carrier-modal`. Title **Create new carrier**. Subtitle **Fill out the information below to create a new carrier**.
  </Step>

  <Step title="Fill required fields">
    Shared fields first, then **Carrier Configuration → Required Fields**. Empty required values make **Create** return without saving.
  </Step>

  <Step title="Create">
    Click **Create** (shows **Creating…** while the request runs) or **Cancel**. Success toast: **Carrier created successfully**. Failure copy in the modal: **Failed to create carrier. Please try again.**
  </Step>

## Shared fields

These appear on every connect dialog, including GLS.

| Field               | Required | What it is                                                                                                                                                                                             |
| ------------------- | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Carrier name \*** | Yes      | Display name in **My Carriers** and on shipments. Placeholder **Enter carrier name**. Defaults to **GLS Denmark**. Letters, numbers, and `. & ' + / ( ) _ -` only.                                     |
| **Brand**           | No       | Only when the organization has [brands](/docs/how-to/create-a-brand). Label **Brand**. Helper: **Only this brand can use this carrier.** Leave unset for organization-wide. Hidden when you have no brands. |

## GLS credentials

**Carrier Configuration** splits into **Required Fields** and **Optional Fields**. Password-labelled fields use a password input. Each helper is catalog copy.

| Field            | Required | Control                                                                         | Where you get it                                                                | Format                                           | Sandbox vs live                                                                                                                                 |
| ---------------- | -------- | ------------------------------------------------------------------------------- | ------------------------------------------------------------------------------- | ------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------- |
| **Login Name**   | Yes      | Text. Helper: **GLS customer number used for API authentication (LoginName)**   | GLS Denmark account / agreement. This is the GLS customer number, not an email. | String. Often the same value as **Customer ID**. | Same field on both hosts. **Sandbox Mode** switches the Label API host.                                                                         |
| **Password**     | Yes      | Password. Helper: **GLS account password**                                      | The password GLS issued for Label API access.                                   | String.                                          | Same field. Use the password that belongs to the environment you selected.                                                                      |
| **Customer ID**  | Yes      | Text. Helper: **GLS customer ID (typically same as login name)**                | GLS Denmark. Usually the same as **Login Name**.                                | String.                                          | Same field on both hosts.                                                                                                                       |
| **Contact ID**   | Yes      | Text. Helper: **GLS contact identifier for your account**                       | GLS Denmark issues a separate contact identifier (not the customer number).     | String.                                          | Same field on both hosts.                                                                                                                       |
| **Sandbox Mode** | No       | Checkbox, default off. Helper: **Enable test mode (uses GLS test environment)** | Zippendo checkbox — not a GLS portal value.                                     | Boolean.                                         | On: `https://labeltest.gls-denmark.cloud/label`. Off: `https://labelapi.gls-denmark.cloud/label`. ParcelShop Finder does not use this checkbox. |

GLS does **not** use OAuth or a developer-portal API key. Credentials travel in every Label API request as `LoginName`, `Password`, `CustomerId`, and `ContactId`.

<Warning>
  Leave **Sandbox Mode** off for live orders. Test credentials on the production host, or live credentials on the test host, fail at send time. Details: [Sandbox mode](/docs/how-to/sandbox-mode).
</Warning>

## After you connect

The connection appears on **My Carriers** with a **Connected** badge and **Edit Carrier**. Products are **not** on this form — they appear when you [create a shipment](/docs/how-to/send-a-shipment) or save a [shipping rule](/docs/how-to/shipping-rule-fields). See [Carrier products and services](/docs/how-to/carrier-products-and-services).

Outbound products include **GLS BusinessParcel**, **GLS PrivateDelivery**, **GLS ShopDelivery**, **GLS Express 10**, **GLS Express 12**, and **GLS GlobalExpress**. Inbound: **GLS ShopReturn**, **GLS Pick\&Ship**, **GLS Pick\&Return**. Sender country for the catalog is Denmark. Weight helper on typical GLS products: **0.1 - 31.5 kg**.

### ShopDelivery (droppoint)

**GLS ShopDelivery** is a service-point product (`isServicePoint`). On **Create Shipment** the card title is **Drop Point** and the required field is **Service Point \***. Pick a GLS ParcelShop before send. Error: **This carrier product delivers to a service point — select a droppoint before sending.** How to pick: [Pick a service point](/docs/how-to/pick-a-service-point). Naming: [Droppoint vs service point](/docs/how-to/drop-point-and-service-points).

ShopDelivery needs recipient **contact, email, and mobile** on the receiver party. PrivateDelivery needs **email and mobile**.

GLS does **not** appear in **Pickups**. Pickup scheduling is Bring and PostNord only — [Schedule a pickup](/docs/how-to/schedule-a-pickup).

Tracking is pulled on a schedule. There is no tracking-webhook field on **Edit your carrier** — [Carrier tracking webhooks](/docs/how-to/tracking-webhooks).

## Edit

On **My Carriers**, click **Edit Carrier**. Page title: **Edit your carrier**. URL `/dashboard/carriers/:id`.

Two cards:

* **General** — **Carrier name** (helper: **Update the name of your carrier**), plus **Brand** when brands exist.
* **Carrier settings** — the same GLS fields as connect, including **Sandbox Mode**.

Header actions: **Delete** and **Save** (pending **Saving…**). Success toast: **Carrier updated successfully**. Loading: **Loading carrier…**. Load failure: **Failed to load carrier. Please try again.** Save failure: **Failed to update carrier. Please try again.**

On **Edit your carrier**, click **Delete**. Modal id `global-delete-modal`. Title **Delete Carrier**.

This action cannot be undone.** Type the carrier name in **uppercase** to enable **Delete**. Toast: **Carrier deleted successfully**. Failure: **Failed to delete carrier**.
