The Meltwater API uses API Keys to authenticate requests.

Authentication to the API is performed by providing the API Key as a header item on the API request.

curl -X GET \
  --url "" \
  --header "Accept: application/json" \
  --header "apikey: **********"

All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.

Changes in Version 3
Note that previous versions of the API required users to use OAuth authentication. This is not a requirement for version 3 of the API. Read more about the changes on the announcements page, including the planned deprecation of previous API versions.
