Versioning

Introduction

Occasionally Spaaza makes changes to the payload sent to or response received from an API endpoint. This may include adding new request or response fields. In order to maintain backwards compatibility with existing API clients a versioning policy is put in place. The aim of this policy is to make using endpoint features as simple as possible.

Usually a Spaaza API endpoint maintains backward compatibility without requiring special flags, but in the case that a specific version is required, the API documentation for that endpoint will show clearly what is needed. If there is no information about versioning in the documentation for a specific endpoint, then there is no need to do anything. Spaaza recommends sending an appropriate version header with all API requests.

Occasionally version-specific changes become available in the Spaaza API which affect multiple, or all, endpoints. This kind of change is described in the section API-wide version information below. Again, this kind of change is designed to be non-breaking and as backwards-compatible as possible.

It should be noted that Spaaza’s approach is generally that we may add optional request fields, or fields to response JSON, without a version change, but that we will only remove fields, or change their type or name, in a new API version, and that that change should avoid affecting API clients consuming endpoints with existing versions.

Using a specific endpoint version

With most Spaaza API endpoints version-specific differences are implemented. In order to use the latest version of an API endpoint, a version header is sent along with the request to the API endpoint. The documentation for a specific endpoint will always contain information about which version number should be used if there are changes differences that are specific to that endpoint.

There are also version-specific differences that apply to all endpoints, such as how errors are formatted in API responses. These are detailed in the ‘API-wide version information’ section below.

The following header is used for specifying a version:

  • X-Spaaza-API-Version: <version number>

Spaaza uses standard semantic numeric major.minor.fix version numbering, for example:

  • X-Spaaza-API-Version: 1.4.10

NOTE that if no X-Spaaza-API-Version header is supplied then a version number of 1.0.0 is assumed.

API-wide version information

This section includes information about version-specific changes which affect multiple, or all, endpoints in the Spaaza API. In the case that these changes affect all endpoints, for example a change in the way error responses are handled between different versions, a description of the change is not usually included in the documentation for any specific individual endpoints.

A description of each of this kind of version-specific change is shown below.

1.5.7 - Multiple updates

  • Added - Maximum values:
    • maximum_basket_total_value_earn: Maximum basket value allowed for campaigns to issue rewards during basket processing
    • maximum_basket_total_value_spend: Maximum basket value allowed for redeeming standalone vouchers in baskets
  • Added - added opt_in_secondary_last_modified_date, which is a datetime field that records the last time opt_in_secondary date changed in User object.
  • Deprecated - the user-specific note field has been replaced by the new Note object, which allows for more flexible and structured note management. The note field will be removed from the response to get-user, get-users and get-card endpoints in version 1.6.0.

1.5.6 - Multiple updates

  • Improved - If a chain does not allow repeated use of retailer_basket_code values for baskets, an exclusive retailer_basket_code parameter in claim-vouchers and lock_voucher will now generate a basket_already_exists error when an associated basket already exists.

  • Improved - the get-campaigns endpoint now supports pagination for API requests.

1.5.5 - Multiple updates

  • Improved - In a return transaction, if it is not possible to match a returned item to an original purchase item, the item will be treated as a negatively-priced purchase item in the returning basket and the excluded_from_spaaza parameter will be set to true to avoid applying any Spaaza campaign logic to the item. See returns documentation for more information.
  • Improved - return a warning in basket endpoints when a returned item cannot be matched to an original purchase transaction
  • Improved - return a warning in basket endpoints when sum of item_price amounts for items does not match basket_total_price value

1.5.4 - Multiple updates

  • Added - Split minimum_basket_total_value into two fields:
