Update Subscriber by ID

The Update Subscriber command allows you to make changes to an existing Subscriber's Data.  See REST API Subscribers Overview for a table of Subscriber data available to PUT.

PUT /subscribers/[subscriberId]


Request Body Parameters

The Update Subscriber by ID command requires the Subscriber ID defined within the URI.  No additional fields are required in the JSON other than those to change, and can be found in the Data Fields table in REST API Subscribers Overview.   

Request Body Example

Using Update Subscriber with all arguments, line breaks in JSON for readability:

--header 'content-type: application/json' \
--header 'accept: application/vnd.whatcounts-v1+json' \
