Components of the API


The Route Optimization API consists of two main components: the input data and the optimization engine.

  • Input Data

The input data includes:

Jobs: Stops or places to visit.

Vehicles: Delivery trucks, vans, etc.

Shipments: Pickup and delivery tasks.

  • Optimization Engine

The optimization engine uses the input data to determine the most efficient set of routes for the vehicles, considering constraints such as capacity, time windows, and vehicle availability. The API can be customized to meet the specific needs of your business.

Let’s look at the steps of how you can use the route optimization API to plan your delivery routes.

Step 1: Set up Delivery Information

To start planning the best delivery routes, you’ll need to set up some basic information about your deliveries. This includes jobs, shipment, depot and location information and vehicles you have. 

First, list the jobs and shipments. Give each job a unique ID, say where it needs to be done, set when it needs to be done, and write down any special skills that are needed. 

jobs in route optimization

Remember to list the items that need to be delivered or picked up and how long you think each job will take.


Next, find your depot, which is the hub where all of your vehicles will start their routes. You must give the depot a unique ID and tell where it is located. 


After that, you can add your vehicles. Each vehicle should have its own ID number and information about when it works, how much weight it can carry, and where it starts. Also, make sure to list any special skills that the driver or the vehicle needs.


Lastly, list all the places that will be involved in the delivery process. Give each one a unique ID and give their coordinates. 


As soon as you have this information ready, you can send it to the route optimization system to start creating the best delivery routes. This setup process ensures that your deliveries are well-organized and work as efficiently as possible.

Step 2: Send Your Data to the Optimization Engine


Now that you’ve set up your delivery details, it’s time to send this information to the optimization engine. To do this, you’ll use the POST method. This method lets you submit all your delivery details and set any rules or constraints you need for the optimization process.

RO POST request

Once you’ve sent your data, the system will give you a unique job ID. Think of this as a reference number for your request. You’ll use this ID to check back and get your optimized routes once the process is complete. It’s a simple way to ensure everything is tracked and managed efficiently.
