Jentic publishes the only available OpenAPI specification for Canada Post Rating API, keeping it validated and agent-ready. The Canada Post Rating Web Service returns shipping rates, available services, prices, and transit times for parcels moving within Canada and internationally. The single POST /rs/ship/price endpoint accepts an XML request describing origin and destination postal codes, parcel dimensions, weight, and optional service or contract identifiers, then returns priced service options for use in checkout and shipping-label workflows.

Use Cases

Patterns agents use Canada Post Rating API API for, with concrete tasks.

★ Checkout Shipping Cost Calculator

E-commerce sites selling into Canada need to display real-time shipping costs at checkout. POST /rs/ship/price with the origin postal code, customer destination, and parcel weight returns priced service options that the cart can render as selectable shipping methods, including transit-time estimates customers see before paying.

POST /rs/ship/price with origin K1A 0B1 and destination V6B 4N7 for a 1.5 kg parcel and present the customer with Regular, Expedited, and Xpresspost options.

Multi-Carrier Rate Comparison

Shipping platforms route parcels to the cheapest or fastest carrier per shipment. Calling Canada Post's /rs/ship/price alongside FedEx, UPS, and other carrier rate endpoints lets a routing engine pick the best option per parcel and per service-level promise.

POST /rs/ship/price for the parcel, call equivalent FedEx and UPS rate endpoints, then select the carrier with the lowest priced service that meets the promised delivery date.

Commercial Contract Rate Quoting

High-volume shippers with Canada Post commercial contracts need contract-specific pricing rather than retail rates. The rating endpoint accepts mailed-by or contract identifiers in the request body to return rates negotiated under a commercial agreement.

POST /rs/ship/price with the contract's mailed-by identifier set, retrieve contract-specific pricing, and surface it on internal shipping dashboards.

AI Agent Shipping Workflows via Jentic

Through Jentic, an agent searches for 'get a Canada Post shipping rate', loads the input schema for /rs/ship/price, and executes the call without managing the Basic Auth credential. Jentic's vault holds the userid:password pair so it never enters the agent's prompt context.

Use the Jentic SDK to search 'get a Canada Post shipping rate', load the /rs/ship/price operation schema, and execute it with origin postal code, destination postal code, and parcel weight.

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

The Canada Post userid and password are stored encrypted in the Jentic vault. Agents receive scoped execution rights and Jentic injects the credential into the HTTP Basic header at call time, so the raw secret never enters the agent's context.

Intent-based discovery

Agents search by intent (for example, 'get a Canada Post shipping rate') and Jentic returns the matching POST /rs/ship/price operation along with its input schema, so the agent can call it without parsing Canada Post's XSD docs.

Time to first call

Direct Canada Post integration: 1-2 days for Basic Auth setup, XML schema mapping, and test-vs-production switching. Through Jentic: under one hour to search, load, and execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Alternative

Shippo API

Shippo aggregates many carriers including Canada Post into a single multi-carrier API, where the Canada Post Rating API is direct and carrier-specific.

Choose Shippo when the agent needs a single integration covering multiple carriers; choose Canada Post directly to avoid an aggregator markup on Canadian-only flows.

Complementary

FedEx Web Services

FedEx provides international shipping rates and services that complement Canada Post's domestic Canadian strengths.

Use FedEx for international parcels with strict delivery SLAs; use Canada Post for residential delivery within Canada.

Complementary

DHL Shipment Tracking Unified API

DHL tracking complements Canada Post pricing when an order ships via Canada Post but transits through DHL international handover.

Pair DHL Tracking for international transit visibility with Canada Post for domestic rate quoting.

FAQs

Specific to using Canada Post Rating API API through Jentic.

Why is there no official OpenAPI spec for Canada Post Rating API?

Canada Post does not publish an OpenAPI specification — its developer portal documents the service in HTML and XSD form only. Jentic generates and maintains this spec so that AI agents and developers can call Canada Post Rating API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Canada Post Rating API use?

It uses HTTP Basic authentication with the userid:password pair issued by Canada Post in the developer portal. Through Jentic, the credential is stored in the Jentic vault and injected into the Authorization header at execution time, so the raw secret never enters the agent's prompt context.

Does the API accept JSON requests?

No. The /rs/ship/price endpoint exchanges Canada Post's XML rating-service schema. Send the XML request body with the appropriate content type and parse the XML response. Jentic surfaces the operation's request shape so the agent can populate it correctly.

How do I quote a shipping rate through Jentic?

Run pip install jentic, then search 'get a Canada Post shipping rate' through the Jentic SDK. Jentic returns POST /rs/ship/price with its input schema. Provide origin postal code, destination postal code, and parcel weight, then execute the operation.

Are there separate test and production environments?

Yes. The OpenAPI spec lists two servers: production at https://soa-gw.canadapost.ca and development at https://ct.soa-gw.canadapost.ca. Use the development environment with test credentials before switching to production.

Can I retrieve transit times alongside prices?

Yes. The rating response includes a service-standard block per priced service that lists the expected transit days and the guaranteed delivery flag, which lets a shipping calculator render a delivery-date promise next to each option.
