Questions & answers
Why integrate the Chronopost API through Sendcloud instead of directly?
Direct Chronopost integration means managing your contract number and Chronotrace password, and if you use Shop2Shop, managing either a sub-account flow or a separate Chronopost contract entirely. Time-specific products (Chrono 10, 13, 18) and the BAL letterbox method add per-product configuration on top.
Through Sendcloud, you authenticate once with your Sendcloud API key and use a single REST schema for Chronopost alongside every other carrier. A direct Chronopost contract is required either way; Sendcloud rates aren't offered for Chronopost.
What happens when Chronopost updates or breaks their API?
Chronopost periodically updates time-specific service definitions, Chrono Shop2Shop routing, and contract-level surcharge rules. Direct integrators absorb credential rotations, payload changes, and method-code revisions for each product variant.
When you ship Chronopost through the Sendcloud REST API, the abstraction layer takes the hit. Sendcloud's engineering monitors Chronopost's documentation and updates the carrier connector internally. Your Sendcloud request schema stays consistent across Chrono 10, Chrono 13, Chrono 18, Chrono Relais Europe, and Chrono Shop2Shop.
Can I use my own Chronopost contract?
Yes, and you have to. Chronopost requires a direct contract; Sendcloud rates aren't offered. Contact Chronopost to activate one first.
In Sendcloud, go to Shipping > Carriers > My Contracts, find Chronopost, and click Add Contract. Enter the contract number and the password you use for Chronotrace. For Chrono Shop2Shop, enter your credentials in the dedicated Shop2Shop fields if it's a sub-account of your main Chronopost contract, or add a separate Chronopost contract if it's standalone. Activating the wrong contract type can incur public-rate surcharges from Chronopost.
Which Chronopost products are supported through the API?
Through Sendcloud, you can ship Chronopost's full express line:
Chrono 10: delivery before 10:00 the next working dayChrono 13: delivery before 13:00Chrono 18: delivery before 18:00Chrono 18 BAL: letterbox delivery for parcels that fit standard letterbox dimensionsChrono Relais Europe: European service-point deliveryChrono Shop2Shop: budget parcel-shop to parcel-shop service (no home delivery, longer transit, separate contract or sub-account)
Which Chronopost-specific features does the API expose?
Chronopost-specific features exposed through the integration:
Time-specific delivery:
Chrono 10,Chrono 13,Chrono 18with destination postal-code eligibility checksBAL letterbox routing: parcels matching letterbox dimensions go directly into the customer's mailbox without signature
Chrono Shop2Shop as a separate sub-account or standalone contract for parcel-shop to parcel-shop economy delivery
Pickup scheduling with a minimum of 5 parcels per pickup
Failed-delivery redirect: parcel held at a Post Office service point for 14 calendar days, or PUDO for 7 days, before return
Shipping rule support to default service-point shipments to Chrono Shop2Shop instead of Chrono Relais Europe
How do I track Chronopost parcels?
Chronopost tracking surfaces time-specific delivery confirmation for Chrono 10, Chrono 13, and Chrono 18. Failed deliveries flag a service-point hold (Post Office for 14 calendar days, PUDO for 7 days) before return.
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 Chronopost return labels?
Chronopost return method availability depends on your contract. The Sendcloud shipping-methods endpoint returns the methods enabled for your account. For Shop2Shop returns, make sure your contract supports the return service or you'll fall back to public rates.
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 Chronopost, 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 Chronopost alongside Colissimo, Mondial Relay, 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 Chronopost's upstream system has issues.
Adding a new carrier later means adding it to your Sendcloud account, not building a new integration.
