How do I encode my Cora `.pem` certificates properly?

Head to Cora Bank's portal and setup an API App yielding you exactly the Client Credentials and a certificate pairing (Public CERT `.pem`/`.crt` and Private `.key`). Go to a UNIX shell / MacOS Terminal: `base64 -i my_key.key` to get the key text, and `base64 -i my_cert.pem` to get the cert text. The unformatted, unbroken blocks are the credentials you paste directly to us.

Does Cora produce a separate Pix link from its Boleto command?

In Cora's domain, executing `cora_create_invoice` natively packages everything. A single entity 'Invoice' acts as both your printable boleto format AND a highly specific Dynamic QR Pix, ensuring multiple avenues for your clients.

Will an outgoing Pix from my chat be instant?

Absolutely. Emitting an explicit request down the `cora_send_pix` route connects instantaneously down Cora's active routing engine (Sistema de Pagamentos Instantâneos - SPI/Bacen) draining specific liquidity.

Can I cancel unpaid user invoices rapidly from MCP?

Of course! Call upon the unneeded identifier within your chat interface, prompting the logic `cora_cancel_invoice`, pulling the document from global banking registration.
