Method	`POST`
Operation	`post_marketing_lists`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Creates a list in the org and answers 201 with it. Name is required; a new list is private, asks public subscribers to confirm, and takes the org's sender for every sender field it leaves empty. A slug the org already uses is 409.

Org admin only.

The method above is the one at the current release of the document. [email protected] (npm) and [email protected] (PyPI) were generated from an earlier release, where this operation carried a different id, so it spells the method differently — regenerating the clients is what makes the two agree.

curl -X POST https://api.hanzo.ai/v1/marketing/lists \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \

MCP reaches marketing through the marketing tool, which names its 82 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_marketing_audiences"
         }
       }
     }'
