Breaking Changes

• When retrieving a single campaign assignment, returns HTTP response code 204: No Content instead of 400: Bad Request if targeting does not match

• API-Key is now needed to call the Decision API

• Global distribution via eight new regional endpoints in Tokyo, Seoul, Sydney, Singapore, Frankfurt, Ireland, Oregon, Ohio, and Northern Virginia

• Error messages format change:

  • JSON object with “message” field

    • /activate: if one of the required fields is missing

      • field: Field is mandatory

    • /campaigns: if there is a variation assignment error (e.g. traffic allocation does not add up to 100%)

      • Error on allocation: visitor untracked

    • /campaigns: If clientId not found

      • Client %s not found. If the request is malformed (i.e. proto unmarshal fails), returns the proto error

    • /campaigns: If the campaignId (custom or generated) is not found

      • The campaign %s is paused or doesn’t exist. Verify your customId or campaignId.
