MATJRAH DEVELOPERS + APPS CENTER

Publish your
Shipping App on Matjrah.

Shipping always starts with a Shipping App. Create it in the Developers Center, declare the carrier services, receive signed shipment jobs, return the AWB and label, then push tracking, cancellation and return states.

THE MATJRAH PLATFORM

One shipping connection across the merchant journey.

Matjrah turns shipping into an installable merchant product—not a loose API credential. The carrier creates and certifies the Shipping App in the Developers Center; merchants find and install the approved app through the Apps Center.

Every merchant approves the app independently. Tokens, shipment records and Webhook deliveries remain isolated by installation and can be revoked without sharing the merchant’s master credentials.

3,500+merchant stores use Matjrah

Per-store installsIndependent scopes, token and shipment ownership

Forward + returnOne shipment contract supports both directions

These are supported partner models, not claims of a ready-made integration with a particular carrier.

SANDBOX CHECKPOINT

One signed shipment event, accepted durably.

Self-service Sandbox proves installation, HMAC verification and delivery of shipment.creating. AWB attachment, tracking, cancellation and tenant isolation must be certified on a provisioned active test store. Understand the environments ↗

BEFORE YOU WRITE CODE

Prepare the carrier side first.

A practical integration starts with three concrete inputs. Have them ready before creating handlers or mapping payloads.

01 / CARRIER API

Prove create, label and cancel

Confirm the carrier sandbox credentials and exact requests for shipment creation, AWB/label retrieval, tracking and cancellation.

Runtime workflow →

02 / HTTPS WEBHOOK

Accept work durably

Expose one HTTPS endpoint that verifies the raw-body signature, stores the event and sends slow carrier work to a queue.

Webhook contract →

03 / MAPPING SHEET

Map services and states

List every carrier service code, coverage rule, COD capability and tracking state beside the documented Matjrah value.

Certification scope →

THE COMPLETE PRODUCT — NOT ONLY AN ENDPOINT

Build the first working shipment in this order.

Complete one vertical slice before expanding services: app installation, signed event, durable claim, carrier request, AWB/label response, then lifecycle updates.

CREATE THE SHIPPING APP

Configure the portal and backend together.

Shipping has one entry path: an approved Shipping App. API and Webhooks operate that installed app; they are not standalone dashboard credentials.

DEVELOPERS CENTERConfiguration

Create and describe the Shipping App

Set up the product merchants will install and the services it exposes.

Choose the Shipping app type
Add app name, logo, support and policy links
Register the HTTPS Webhook URL
Declare carrier codes, coverage, defaults, periods and COD

YOUR BACKENDRuntime

Build one safe shipment worker

Keep the Webhook response fast and move carrier work behind a durable claim.

Verify HMAC against the exact raw body
Store each installation token separately
Deduplicate by request and shipment IDs
Map the carrier result and attach AWB/label idempotently

ALREADY BUILT FOR SALLA?

Keep the carrier logic.
Replace the platform adapter.

If your Salla app already creates AWBs, labels and tracking updates, do not rebuild the carrier integration. Preserve that proven layer and add a Matjrah Shipping App adapter for installation, signed events, shipment ownership and callbacks.

REPLACE

The commerce-platform edge

Salla OAuth → signed app.installed
Salla token lifecycle → per-store ait_…
Salla event verifier → raw-body Matjrah HMAC
Salla shipment payload → shipment.creating
Salla callbacks → Matjrah attach, track and cancel

FOCUSED PROTOTYPEOne working shipment in 24 hours

A practical target when the existing Salla app and carrier API already work—not a production or certification guarantee.

01Inventory the Salla adapter without editing
02Add Matjrah installation + signature verification
03Map one shipment.creating fixture
04Return one AWB and label idempotently

What the AI agent must leave behind: inventory.md, mapping.md, gaps.md, test-plan.md, a separate Matjrah adapter, and tests for invalid signatures, duplicate delivery, tenant isolation and retry safety.

Never send production tokens, recipient data or real payloads to an AI tool unless your organization has approved that tool and its data controls.

THE SHIPMENT RUNTIME

Receive the job, return the shipping truth.

API and Webhooks are the runtime of an approved, installed Shipping App—not a separate integration path. Verify the exact raw Webhook body, persist request_id and shipment_id, and use only that installation's token.

01 / MANIFEST

Services and defaults

Declare carrier codes, countries, zones, default cost, delivery period and capabilities such as COD.

02 / WEBHOOK

`shipment.creating`

Receive order, recipient, items, weight, COD amount and direction: forward | return in the signed event.

03 / AWB + LABEL

`PUT /v1/shipments/{id}`

Attach the AWB, tracking number, stable tracking link and optional label URL to the exact shipment.

04 / LIFECYCLE

Track or cancel

Push picked-up, in-transit, out-for-delivery, delivered, returned or failed states; cancel with the dedicated endpoint.

REVIEW READINESS

A Shipping App merchants can operate

Certification starts with shipment ownership and failure recovery, not listing copy.

Signature verificationVerify HMAC against the exact raw body before parsing.
Durable deduplicationDo not create a second carrier shipment for a repeated request_id or shipment_id.
Tenant isolationNever mix install tokens, shipment queues, labels or logs across stores.
Complete callbacksReturn AWB and label, then push tracking, cancellation and terminal states.
Actionable monitoringCorrelate errors to the installation and shipment without exposing secrets or recipient data.

CREATE YOUR SHIPPING APP

Package your shipping service for Matjrah merchants.

Start by creating a Shipping App in the Developers Center. If you represent a courier, shipping aggregator or 3PL provider and need technical or commercial alignment, schedule a conversation. For app integration support, email dev@matjrah.com.
