Root causes identified from logs: 1. All params (login, password, cmd, email, etc.) were appended to the URL query string; phpList REST API v3 expects them in the POST body. wp_remote_post now sends body=>$params instead of an empty body. 2. subscriber_get_by_email and subscriber_add called rawurlencode() on the email before passing it to call(), which then ran http_build_query() on it again — double-encoding '@' to '%2540'. Both rawurlencode() calls removed; wp_remote_post handles POST body encoding correctly. Additional improvements: - endpoint_url() returns just the bare ?page=call&pi=restapi URL - On API error, log full_response (entire JSON) not just the message field, so phpList's exact reply is always visible in WC Status Logs - Non-JSON response now gives an explicit error message pointing to the endpoint URL / credentials rather than a generic JSON parse failure Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
