Courier API Integration
Connect your application to courier and shipping services so shipments are created, labelled and tracked programmatically instead of by hand.
The connection itself is rarely the hard part. What decides whether an integration holds up is how it behaves when a partner is slow, rate-limits you, times out, or returns success and then does nothing.
What an integration covers
Booking through to reconciliation.
- Shipment creation and cancellation
- AWB and label generation
- Tracking and status sync
- Webhooks and callbacks
What is courier API integration?
Courier API integration is the work of connecting your own system to a courier company's API so that operations which would otherwise be done in that courier's portal — creating a shipment, generating an AWB, printing a label, checking a pincode, pulling tracking — happen automatically inside your software.
For a single courier this is a contained piece of work. Across several partners it becomes an ongoing commitment, because each one has its own authentication, its own field names, its own status vocabulary and its own failure modes.
Supported integrations depend on the courier provider's available APIs, credentials and permissions. Which partners can be connected, and how deeply, is confirmed during requirement analysis rather than assumed.
What It Covers
Booking & Cancellation API
Create shipments programmatically with sender, receiver, package and payment details, and cancel cleanly when an order is pulled before dispatch.
AWB & Label API
Retrieve AWB numbers from a partner's series and generate labels in the exact format their hub expects. A label that does not scan is a shipment that stalls.
Serviceability API
Check origin and destination coverage before a shipment is created, so failed bookings are caught at order time rather than at dispatch.
Rate API
Pull live rates for weight, dimensions, destination and service level, which is what makes automated courier selection possible.
Tracking API
Poll or receive status updates and map them into one consistent model, so your tracking page reads the same regardless of who carried the parcel.
Webhooks
Take pushed updates where a partner supports them, with signature verification and a queue so a webhook storm cannot overwhelm the application.
Building an integration that stays up
Credential & auth handling
API keys, tokens and refresh flows stored securely per partner and per environment — never hard-coded, never shared between sandbox and production.
Retries with backoff
Transient failures are retried with exponential backoff rather than hammering a partner that is already struggling, which is how you get rate-limited.
Idempotency
A retry must never create a second shipment. Requests carry an idempotency key so the same booking cannot be duplicated by a timeout.
Status normalisation
Each partner's vocabulary is mapped into your own status model. Without this, one courier's “In Transit” covers what another splits across three states.
Queuing & fallback
Bookings that cannot complete go to a queue rather than failing silently, so nothing is lost when a partner has an outage.
Logging & monitoring
Requests, responses and failures are logged, with alerting so you find out a partner changed their API before your customers do.
