Count lists
Count the lists that match the v2 pagination filters.
POST /v2/lists/paginate would return for the same request body. It replaces the deprecated POST /v1/lists/count.
The count ignores limit and page, so it reports every matching list rather than one page of them.
Filter by list ID
Usefilters.id to count one or more specific lists.
Authorizations
Recommended authentication for new integrations. Generate a short-lived JWT from your API Secret ID and API Secret Key, then pass the signed JWT as a bearer token in the Authorization header.
API Secret credentials are available in the Heymarket app under Settings > Integrations > API. The Secret Key is shown only when it is generated, so copy and store it securely before closing the dialog.
Use the following JWT values:
Replace CURRENT_UNIX_TIMESTAMP with the current Unix timestamp in seconds when generating the token.
Sign the JWT with HMAC-SHA256 using this signing secret:
Send the signed JWT as a bearer token:
Tokens expire 5 minutes after the iat timestamp. Generate a new JWT per request, or cache it briefly for less than 5 minutes. Generate JWTs only from trusted server-side code; do not expose the API Secret Key in browser, mobile, or other client-side code.
