As previously mentioned on this blog, we will migrate to the newest version of our API on Thursday 18th July.
The v4 API will become the “current” API version and be available at /api AND /api/v4. If you use V2 or V3 of our API, they will continue to work but eventually you will need to hard code those URLs for the service to keep working.
This upgrade only affects the endpoint of the /api/bulk/articles. If you do not use this feature, your API integrations will continue to work normally.
