Retrieve utility bill statements and interval data using the Arcadia (Arc) utility data API

Steps

1. Obtain API credentials (client ID and client secret) from Arcadia's developer portal; exchange them for an access token via the OAuth 2.0 client credentials flow at the token endpoint.
2. Initiate a user credential or OAuth-based utility connection for a customer by calling the credentials or OAuth link endpoints, directing the customer to authorize data access with their utility.
3. Once connected, retrieve the list of utility accounts for the customer via GET /accounts, then fetch statement (bill) data for a specific account using the statements endpoint.
4. Pull interval meter data via the intervals endpoint for a given account, specifying date range parameters to bound the query.
5. Handle pagination in responses using the cursor or page tokens returned in the response envelope, and subscribe to webhooks for new statement or interval data events to avoid polling.
