Questions

How does LuumenAI connect to Taxjar?

Authorize once with API token. Luumen lists the scopes each action needs before you approve the connection, and credentials never appear in the chat.

Can LuumenAI change things in Taxjar on its own?

Read actions answer immediately. Anything that writes — create customer, create order transaction, create refund transaction, delete customer, and more — is shown as a plan and requires approval by default, including the 3 actions classified as destructive. Administrators configure that per tool, so you decide exactly which actions can ever run unattended.

Who gets access to the integration?

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.

Is there an audit trail?

Every call to Taxjar — 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.
