How BillerAPI works

Create a Link Session

Your server calls POST /link/token/create to get a link token for the Connect SDK.

User connects their biller account

The Connect SDK guides the user through selecting a biller and entering credentials.

Exchange for an access token

Your server exchanges the public token via POST /link/token/exchange.

Retrieve bills

Use the access token to fetch bills via GET /bills/get. Webhooks notify you of new bills.
