Get started

To use the Subscription Timing API, you must first configure your account. Guidance can be found in the Subscription Timing documentation. This document provides instructions for using the API.

Retrieve subscription timing guidance from the Subscription Timing API

The Shipium Subscription Timing API is designed to be flexible to fit your organization’s business strategy and technical capabilities. All API calls assume you're using one of the authentication mechanisms detailed in our authentication documentation. The endpoint for all Subscription Timing API calls is included in the table below.

API type	API endpoint
POST	https://api.shipium.com/api/v1/subscription/timing

The following table provides all required and optional field descriptions for calling the Subscription Timing API. You can find additional support in the Subscription Timing API Reference.

Request field	Required/Optional	Field properties	Description
`customerCountryCode`	Required	string enumeration Limited to 2 characters and ISO 3166 standards	Shipment’s destination country
`customerPostalCode`	Required	string Limited to valid USPS postal ZIP codes	Shipment's destination postal code
`desiredDeliveryDate`	Required	string date Limited to the ISO-8601 standard OR a date only in `YYYY-MM-DD` format.	The date on which you want the shipment in question to be delivered on or before. Note that this value should be in the timezone of the delivery postal code. If you provide only date, that will be assumed.
`options.shippingOptions.fromCountryCode`	Optional, but must be paired with `fromPostalCode`	string enumeration 2 character ISO 3166 standards country code	Dictate the origin that will fulfill the shipment by using the country code and postal code.
`options.shippingOptions.fromPostalCode`	Optional, but must be paired with `fromCountryCode`	string enumeration Valid USPS postal ZIP code value	Dictate the origin that will fulfill the shipment by using the country code and postal code.
`options.shippingOptions.originId`	Optional	string enumeration Shipium-generated originID value for the particular origin	Dictate the origin that will fulfill the shipment by using the origin ID.
`options.shippingOptions.shipOption`	Optional	string enumeration One of the valid values for `shipOption`, listed below.	Dictate the ship option that will be used and thus the likely ship time available for the shipment, if needed.
`referenceIdentifiers.name`	Optional	string No character limitations	Optionally include your organization's own identifier to be associated with the shipment for internal tracking.
`referenceIdentifiers.value`	Optional	string No character limitations	Optionally include your organization's own value to be associated with the specified name, associated with this shipment for internal tracking.

The primary elements of the response (other than the request elements) are listed in this table. The primary pieces of data returned are the fcDropDate and the shipByDate, representing when a shipment should be sent to the fulfillment center (FC) and when it should be shipped, respectively, in order to get it to the customer by the requested desiredDeliveryDate.

Response attribute	Description
`subscriptionTimingId`	Unique Shipium-generated ID associated with the request and response
`fcDropByDate`	The date by which the fulfillment center (FC) should begin processing of the shipment in order to hit the desired delivery date that was requested. This value is calculated based on the `shipByDate` and a calculation using the FC processing time configured for the appropriate origin.
`shipByDate`	The date by which the FC should ship the shipment in order to hit the desired delivery date that was requested.
`estimateSource`	The source of the times in transit (TNTs) that were utilized as part of the calculation. This will be one of `"ShipiumCalculated"`, `"PartnerProvided"`, or `"CarrierProvided"`.

In addition to these primary elements of the response, if the desired delivery date provided in the request would require a ship date in the past, the shipDateExceptions attributes in the following table will be returned in the response.

Response attribute	Description
`shipDateExceptions.exceptionType`	The type of exception for the ship date calculation exception
`shipDateExceptions.exceptionDescription`	A description of the type of exception for the ship date calculation exception
`shipDateExceptions.effectiveShipByDate`	Provides an effective ship-by date in the local timezone of the origin
