For Agents

Access La Banque Postale PSD2 open banking endpoints: read account balances, owners, overdrafts, and transactions, and initiate or confirm payment requests.

Install Jentic One Beta

Connect the La Banque Postale PSD2 API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the La Banque Postale PSD2 API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Use Cases

Patterns agents use La Banque Postale PSD2 API for, with concrete tasks.

★ Account Aggregation (AISP)

Aggregate a customer's La Banque Postale balances and transactions into a personal-finance dashboard. Under PSD2 AISP consent, GET /v2/accounts enumerates the user's accounts, GET /v2/balances returns balances, and GET /v2/transactions returns paginated transaction history. Owners and overdrafts can be enriched on demand from /owners and /overdrafts.

GET /v2/accounts to list accounts, then GET /v2/balances and GET /v2/transactions for each account ID to populate a dashboard view.

Payment Initiation (PISP)

Initiate SEPA-style payments from a La Banque Postale account on behalf of an authorised user. POST /v2/payment-requests creates a payment request, the user authenticates with Strong Customer Authentication on the bank's side, and POST /v2/payment-requests/{id}/confirmation confirms execution. The intermediate state can be inspected via GET /v2/payment-requests/{id}.

POST /v2/payment-requests with debtor account, creditor account, and amount, await SCA, then POST /v2/payment-requests/{id}/confirmation to execute.

Reconciliation Pipeline

Pull La Banque Postale transactions into an accounting system for daily reconciliation. The agent reads /v2/transactions on a schedule, deduplicates against last-seen IDs, and writes new transactions into the ledger. /v2/balances acts as the daily closing-balance check.

GET /v2/transactions with the date range since the last sync, write new transactions into the ledger, and GET /v2/balances to record the day's closing balance.

AI Agent Banking Assistant

An assistant in a banking app reads balances, summarises spending, and initiates payments on instruction from the account owner. Through Jentic, the assistant calls La Banque Postale's PSD2 endpoints by intent without holding the OAuth refresh token in the agent context, and SCA stays inside the bank's own flow.

On 'pay 250 EUR to my landlord today', POST /v2/payment-requests with the saved beneficiary IBAN and 250 EUR, then prompt for SCA and POST /v2/payment-requests/{id}/confirmation.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

OAuth tokens for La Banque Postale's PSD2 endpoints are stored encrypted in the Jentic MAXsystem vault. Refresh tokens are rotated automatically and the agent runtime never holds long-lived banking credentials.

Intent-based discovery

Agents search by intent (e.g. 'read La Banque Postale balances' or 'initiate a SEPA payment') and Jentic returns the matching PSD2 operation with its input schema.

Time to first call

Direct PSD2 integration: 1-2 weeks for OAuth, eIDAS QWAC handling, and SCA flows. Through Jentic: under 1 hour once the licensing prerequisites are in place — search, load, execute.

FAQs

Specific to using La Banque Postale PSD2 API through Jentic.

Why is there no official OpenAPI spec for La Banque Postale PSD2 API?

La Banque Postale publishes documentation on developer.labanquepostale.com but does not expose a single canonical OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call La Banque Postale PSD2 API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the La Banque Postale PSD2 API use?

The API uses OAuth 2.0 authorization code flow under PSD2 rules. The user authenticates with the bank, grants AISP or PISP scopes to a licensed third-party provider, and the access token is then included on each request. Through Jentic, tokens are stored encrypted in the MAXsystem vault.

Can I initiate a payment with the La Banque Postale PSD2 API?

Yes. POST /v2/payment-requests creates the payment request, and POST /v2/payment-requests/{id}/confirmation finalises it after the user completes Strong Customer Authentication. GET /v2/payment-requests/{id} reads the current status.

How do I read account balances through Jentic?

Search Jentic for 'retrieve La Banque Postale balances'. Jentic returns GET /v2/balances with its schema. Provide the account context resolved from /v2/accounts and Jentic executes the call using the stored OAuth access token.

Do I need a PSD2 licence to use the La Banque Postale PSD2 API?

Yes. AISP endpoints require an AISP licence and PISP endpoints require a PISP licence (or registered agent status). The bank validates the third-party provider's eIDAS QWAC certificate during the OAuth flow.

What rate limits apply to the La Banque Postale PSD2 API?

PSD2 introduces minimum service-quality requirements rather than fixed rate limits. Refer to developer.labanquepostale.com for the current operational limits and aggregator-specific ceilings before scaling agent traffic.
