# join\_product

Generated automatically from the [published contract sources](/reference/about#contract-sources).

**Build metadata:** Registered in this build. Registration describes the default dispatcher in this build. It does not guarantee that a caller has the required credential or grant, that a tool is listed for that connection, or that the required service is configured.

A script calls this action over HTTPS at `POST https://turnzero.ai/api/v1/actions/join_product`, with a bearer credential and the action's payload as the JSON body.

## Contract description

Add tzCloud to this account, the act the account page's Enable control makes\. Name \`product\` as \`cloud\`\. The join takes one of Cloud's open places and is refused \`realm\_creation\_ceiling\` while none is open; an invitation that names Cloud adds it whatever the count\. An account that already holds Cloud answers \`joined: false\` with nothing changed\. Refused \`account\_door\_not\_yet\_served\` on an estate whose operator has not lifted the account door\. tzTeam comes by invitation; no other product is joined here\.
