Switching API version from 4.0 to 4.1

Modified on: Tue, 19 Feb, 2019 at 12:29 PM

What is the difference between version 4.0 and 4.1 ?

Version 4.1 is more secure in a way, that it stores the API key in the header rather than the URL.

What changes need to be done in order to switch from 4.0 to 4.1 ?

There are mainly 3 changes that are required as listed below,

Ask your CSM or write to our support asking to change your API version from 4.0 to 4.1
Change in the URL
The URL's will contain additional text "/v4.1/". All the support articles have already been updated to refer to v4.1
Change in Authentication parameter

The Authentication parameter has to be passed in Header rather than the URL as below.

Key	Value
Authorization	api_key<space><your_api_key>

Curl Example

curl -X GET -H "Authorization: api_key <api_key>" "https://api.eu.customergauge.com/v4.1/transactions/response.json?days=1"

You can browse the API 4.1 folder for list of available APIs.
