Before you begin #

1. Open the Colissimo settings #
In the Shipping menu, open Shipping services, then open the Colissimo service you want to configure.
The field names below match the English interface shown in the screenshot.
2. Identify the shipping service #
| Field | What to enter |

| Password | The password associated with your connection credentials. Its contents are masked on screen. |
| WebserviceKey / User key | These fields are also available. Their use depends on the connection method: confirm which values your configuration requires before filling them in. |
4. Choose your label settings #
| Field | Purpose |
|---|---|
| Default label format | Select a format suitable for your printer. The two main choices are PDF10x15300DPI and PDFA4300dpi; see the explanations below. |
| Default service code | Select the service that matches your shipments and contract. The example shows France – Colissimo Domicile – sans signature (DOM) (home delivery without signature). |
| Default weight | Default weight field. The unit and the conditions under which it applies still need to be confirmed for this version of the application. |
| Default deposit delay | Default parcel handover delay field. The unit and the calculation of the handover date still need to be confirmed. |
| Sign by default | Default signature setting. The accepted values and how this setting interacts with the selected service still need to be confirmed. |
| Return label by default | Choose whether to generate an outbound label only, a return label only, or both. The three options are detailed below. |
| Label naming rules | Label file naming rules. The available syntax still needs to be confirmed before an example can be provided. |

Which label format should you choose? #
| Format | When to use it |
|---|---|
| PDF10x15300DPI | A PDF label measuring 10 × 15 cm, at 300 dpi. This format is suitable for professionals using a dedicated printer for self-adhesive labels. |
| PDFA4300dpi | A format for printing on an A4 sheet. It is suitable for individuals and beginners, as well as return labels intended for individual customers. |
| Other formats (ZPL and DPL) | These formats are used less frequently, for the needs of certain professional users. |
Should you generate a return label? #
| Return label by default option | Result |
|---|---|
| Blank option | Only an outbound label is generated. This is the most common choice. |
| Return label only | This Colissimo account produces return labels only, with no outbound label. |
| Both go and return label | Both an outbound label and a return label are generated. Place the return label inside the parcel so the end customer can use it to return their shipment. |
