Enable Banking vs Powens

Enable Banking

Restricted mode gives live data for your own whitelisted accounts before any contract. No public prices and a minimum monthly invoice.

Powens

Powens documents a REST API with Markdown docs, cursor pagination, date filters and a hard-delete call for connections, under a French payment institution licence. No OpenAPI file, public price, status page, idempotency key or server SDK was found, and live access needs a signed purchase order.

Enable Banking

1. Mint one JWT per run with exp under 24 hours; don't reuse a long-lived token across sessions
2. Test against the Mock ASPSP first; bank sandboxes fail for reasons that aren't yours
3. Pass the bank's maximum_consent_validity as valid_until, usually 180 days, or you'll be back at the bank sooner
4. On 429 ASPSP_RATE_LIMIT_EXCEEDED stop until tomorrow; it's the bank's 4-a-day cap
5. Follow continuation_key until it's absent to get every transaction

Powens

1. Ask the owner for the domain name, client ID and client secret from the console. Every call goes to https://{domain}.biapi.pro/2.0
2. Send limit on every transactions list. It is required, at most 1,000, and the next page comes from _links.next.href used as given
3. Enable an account with POST and {"disabled": false} only after the account holder consents. Accounts arrive disabled with no transactions
4. Store the permanent user token as a secret. It does not expire, and the default webhook sends it in the Authorization header
5. Stay under 30 calls a minute in the sandbox and use webhooks in place of polling, as the fair usage policy asks
