Use Enable Banking through Slack with Giga.

1. Sign in to the Enable Banking control panel and register an application (start with the Sandbox environment).
2. When registering, choose "Generate in the browser" to create the key pair, and download the private key (PEM) after registration — or upload your own self-signed certificate.
3. Copy the application's Application ID — that's the key id below.
4. Paste the Application ID and the PEM private key. The vault signs a fresh 1-hour RS256 JWT for every API call; your private key never leaves the vault.

Once connected, the agent drives the account flow through the proxy: POST /auth (returns a bank redirect), then POST /sessions with the returned code, then GET /accounts/{id}/transactions.
