This endpoint is used to unsubscribe from an event.

The following example shows how to unsubscribe from an event by submitting a DELETE request on the REST resource using cURL.

curl -v -u <username>:<password> -X DELETE \
  '<restproxy of your blockchain instance>/api/v2/channels/default/event-subscriptions?role=<role>&user-id=<username>&subscription-id=<subscription ID>&channelId=<channel ID>'

For example,

curl -v -u obpuser:<password> -X DELETE \
  'https://myvm.oracle.com:10000/restproxy/api/v2/channels/default/event-subscriptions?role=myinstance_defaultuser&user-id=user1&subscription-id=testuser1-dc28b77c-7e58-4b09-ae23-b2c01fa01b70&channelId=default'

Note:

You can find the rest proxy value of your blockchain instance from the Nodes tab of your instance console.
