Questions & answers
Why integrate the Mondial Relay API through Sendcloud instead of directly?
Direct Mondial Relay integration means handling the Security Settings document credentials (Product ID, Private Key, API v2 password), separate Connect portal credentials, and per-country Point Relais routing. Through Sendcloud, you authenticate once with your Sendcloud API key and use a single REST schema for Mondial Relay alongside every other carrier in your account.
Sendcloud absorbs upstream changes from Mondial Relay. With Sendcloud rates, you also get full postal-code home-delivery coverage in France and Monaco out of the box, without contract-level coverage configuration.
What happens when Mondial Relay updates or breaks their API?
Mondial Relay periodically updates the Security Settings document format, the Connect portal authentication, and the QR-code labelless flow. Direct integrators have to refresh credentials, re-test payloads, and adjust to changes in QR-code label generation.
When you ship Mondial Relay through the Sendcloud REST API, the abstraction layer absorbs those changes. Sendcloud's engineering monitors Mondial Relay's developer docs and adjusts the carrier connector internally. Your Sendcloud request schema stays the same whether Mondial Relay updates Point Relais routing or QR-code generation logic.
Can I use my own Mondial Relay contract?
Yes. Sendcloud supports both Sendcloud-negotiated Mondial Relay rates and your own direct contract.
Sendcloud rates give you full postal-code home-delivery coverage in France and Monaco out of the box. With a direct contract, postal-code coverage depends on the services enabled in your Mondial Relay contract; check with your Mondial Relay account representative.
For your own contract: open a professional account on the Mondial Relay portal first. Then go to Shipping > Carriers, find Mondial Relay, click Enable, and add your contract under My Contracts with the Product ID (8 characters), Private Key (8 characters), and API v2 password from your Mondial Relay Security Settings document.
See the Mondial Relay contract activation Help Center article.
Which Mondial Relay products are supported through the API?
The integration covers Mondial Relay's home delivery and click-and-collect services:
Mondial Relay Home Delivery: full postal-code coverage in France and Monaco (Sendcloud rates), 0 to 25 kg, 48 to 72 hour transitMondial Relay Point Relais L: domestic Point Relais drop-off and pickup, up to 30 kgMondial Relay Point Relais International: cross-border Point Relais delivery to France, Belgium, Spain, Luxembourg, and the NetherlandsQR-code (labelless) variants for parcels labeled at the Point Relais
Note: parcels must be handed to Mondial Relay directly, even if last-mile partner names appear on the shipping label.
Which Mondial Relay-specific features does the API expose?
Mondial Relay-specific features exposed through the integration:
QR-code labelless shipping: the API returns a QR code instead of a printable label; the recipient or sender presents it at the Point Relais and the label prints there
Point Relais routing across France, Belgium, Spain, Luxembourg, and the Netherlands (5 days dwell time at service points and lockers domestically; 14 days for some international Point Relais)
Mandatory mobile phone number on the shipment (landlines and French overseas numbers not accepted; phone number does not appear on the label per GDPR)
Pickup scheduling for high-volume merchants (350+ parcels per month)
How do I track Mondial Relay parcels?
Mondial Relay Point Relais drop-off events and locker arrival events flow through Sendcloud's webhook stream alongside standard delivery events. Tracking covers both home delivery and click-and-collect flows, with mandatory mobile phone numbers feeding into recipient SMS notifications.
All events normalise to Sendcloud's status taxonomy through GET https://panel.sendcloud.sc/api/v2/tracking/{tracking_number}, with the chronological history under statuses and each event mapped to parent_status. Subscribe to the parcel-status-changed webhook for push updates. Reference: Tracking parcels.
How do I create Mondial Relay return labels?
Mondial Relay's QR-code return flow lets recipients drop returns at any Point Relais without printing a label at home. The Sendcloud API returns a QR code instead of a printable label; the recipient scans it at the Point Relais and the label prints there.
All return labels are created through Sendcloud's standalone v3 Returns API (synchronous or asynchronous; async is recommended for higher throughput). No outgoing parcel lookup or JWT tokens are required. Reference: Returns API overview.
How does Sendcloud's multi-carrier API compare to connecting carriers individually?
The Sendcloud REST API gives you access to 170+ carriers, including Mondial Relay, through one credential set, one schema, one webhook stream, and one error model. Connecting carriers individually means handling separate authentication, payload formats, and tracking systems for each, and redoing the work every time a carrier ships breaking changes upstream.
With Sendcloud, you ship Mondial Relay alongside Colissimo, Chronopost, DPD, and DHL, or any other carrier in your account using the same code. Route shipments between carriers based on rules (weight, destination, service level, cost) without writing carrier-specific routing logic. Fall back to alternative carriers automatically if Mondial Relay's upstream system has issues.
Adding a new carrier later means adding it to your Sendcloud account, not building a new integration.
