Postgrid
for LuumenAI
Check on mailed letters, cheques, and postcards — and send or cancel with approval
Connect PostGrid and Luumen can look up any letter, cheque, postcard, box, or tracker by ID, read the contacts and templates behind them, and list bank accounts. Sending new mail, ordering return envelopes, or canceling a cheque runs as a previewed step you approve first. Luumen authenticates with an API key.

Questions
Authorize once with API token. Luumen lists the scopes each action needs before you approve the connection, and credentials never appear in the chat.
Read actions answer immediately. Anything that writes — cancel box, cancel cheque, cancel cheque with note, cancel postcard, and more — is shown as a plan and requires approval by default, including the 12 actions classified as destructive. Administrators configure that per tool, so you decide exactly which actions can ever run unattended.
You decide. Actions are granted per agent, skill, and team, and per environment — production is not staging. Read access can be broad while writes stay narrow.
Every call to Postgrid — read or write, approved or declined — is recorded with the actor, the input, and the result, and can be linked to the ticket or change record.
