# Mercury

> Connect a Mercury business banking account with a read-only API token.

## Setup

Create a Read Only API token in Mercury under Settings → API tokens. Read-only tokens need no IP allowlist. Name the connection after the organization, for example “Mercury: Evident”.

Add the connection under **Settings -> Connections**. Saving verifies it with a read-only test call.

## Operations

All operations are read-only. Apps declare the ones they use per connection; see [Using connections in apps](/connections/overview).
