Singapore Post Trackings API

Create a tracking

Creates a new tracking object.

Parameters

  • tracking_number string required
    Tracking number of a shipment. Duplicated tracking numbers, tracking numbers with invalid tracking number format will not be accepted.
    Only accept tracking numbers with length from 4 to 100
  • slug string, static singapore-post.
  • title string
    By default this field shows the tracking_number, but you can customize it as you wish with any info (e.g. the order number).
  • order_id string
    A globally-unique identifier for the order.
  • order_promised_delivery_date string
    The promised delivery date of the order. It uses the format YYYY-MM-DD. This has no timezone and uses whatever date you provide. Since other EDDs use the shipment recipient’s timezone, we suggest following the same logic here.

Returns

Return a tracking object if the call succeeded.
