Deblock Banking App API Integration for OpenData/OpenFinance

1) Transaction history & categorized ledger export

Deblock exposes a booking timeline that includes EUR movement and crypto-related conversion activity. We map each entry into stable ledger events (id, postedAt, amount, currency, counterpart hints, and reference text) so your ERP/accounting system can reconcile without relying on UI wording.

2) Balances & crypto holdings snapshot sync

The app’s wallet + account model creates a frequent need for “where is the money right now?” data. We build balance adapters that output both EUR account totals and crypto holdings snapshots, including valuation timestamps so dashboards do not drift when exchange rates update.

3) IBAN & SEPA transfer status API (instant + references)

Deblock’s SEPA capabilities are described as part of a bank connectivity integration (including SEPA credit transfer, SEPA instant credit transfer, and SEPA direct debit). We normalize transfer instructions into OpenFinance objects that track status changes and reference identifiers end-to-end.

4) Visa debit card activity + receipt metadata

Multiple Visa debit cards (physical and virtual) make spending data spread across card identities. We aggregate card activity into one payment ledger and map fields to a unified contract: cardId, transactionId, auth/post dates, merchant labels, and amounts with currency.

5) Crypto exchange ledger: buy/sell/swap + fee-aware mapping

Deblock supports buying, selling, and swapping crypto assets and provides deposits/withdrawals across BTC, Solana, USDC and more. Integration teams typically need an accounting-friendly “trade ledger” that breaks operations into legs (assetIn/assetOut, rate, and fee indicators) without losing traceability.

6) Tax-ready transaction export workflow

Sources describing Deblock mention that users can download transactions instantly for reporting. We treat this as a time-windowed export feature and implement an OpenData-to-OpenFinance pipeline that validates completeness and produces deterministic CSV/JSON bundles for your tax/reporting workflows.

OpenData first, then OpenFinance-ready outputs

We separate raw exports (for audit traceability) from derived finance objects (for analytics and accounting). This makes it easier to re-normalize fields when new wallet screens or rounding rules appear after app updates.

In practice, your system can keep ledger event IDs stable across runs, while we attach mapping metadata for later backfills.

Protocol analysis with explicit consent boundaries

Because Deblock is regulated in France and operates with sensitive financial data, we design the connector around user authorization, token lifetimes, and revocation. The goal is to prevent “silent” ingestion and to make consent scope auditable.

Your engineers receive a consent-aware integration pattern you can document in project security reviews.

Field contracts that match real accounting needs

Instead of mirroring UI labels, we publish stable field names for your ledger: booking references, postedAt timestamps, amount/currency pairs, asset legs for trades, and status transitions for SEPA events.

That reduces brittle integration code when Deblock’s UI evolves.

Step-by-step integration workflow

1. Scope alignment: confirm which modules you want (ledger export, SEPA status, card ledger, crypto trade map, or tax bundle exports) and define update cadence.
2. Authorized protocol analysis: document the app journeys that produce the needed data (login/session state, export actions, and status progression) and define consent boundaries.
3. Data ingestion + normalization: implement paging, date ranges, and field mapping into your OpenData records and OpenFinance ledger objects.
4. Output API contract: expose stable endpoints with structured errors (token expired, consent revoked, export not ready) and retry/idempotency guidance.

What you receive

• API contract (OpenAPI-style specification) for your ledger and statement export endpoints.
• Protocol analysis report describing consent/token assumptions and session lifecycle.
• Runnable integration source code (adapter + client SDK) in your preferred language.
• Test plan + sample requests/responses, including negative tests for common failure modes.
• Compliance notes for GDPR/PSD2-style consent, data minimization, and secure storage.

Scenario 1: ERP reconciliation from Deblock ledger export

A finance team needs daily reconciliation between bank statements and their internal ledgers. They want a workflow that pulls bookings reliably and maps the entries into consistent accounting objects, even when the UI changes.

Scenario 2: SEPA instant status automation for rent & payroll

A property manager pays rent schedules and wants to track when SEPA instant transfers actually post. The integration must keep transfer reference strings and update status as soon as the app reports changes.

Scenario 3: Unified fiat + crypto portfolio dashboard

A fintech dashboard wants a single screen for EUR cash position and crypto holdings. The system also needs a consistent valuation timestamp so charts do not jump due to partial refreshes.

Scenario 4: Trade ledger export for accounting + compliance review

An operations team needs to produce a “trade ledger” that distinguishes conversion legs, identifies asset pair direction, and captures fee indicators in a tax-friendly way.

Scenario 5: Tax export pipeline with deterministic bundles

A user-facing tax assistant needs scheduled export bundles (month/quarter) and must re-run jobs idempotently. Missing records must be detected before the final report is delivered.

1) Authorized session bootstrap (consent + token lifecycle)

We implement the connector so it never runs outside an explicit consent scope. In your system, the adapter returns a short-lived access token and a `consentId` for audit logs and revocation handling.

2) Statement/transactions export with paging + normalization

Exports are fetched in time windows, normalized into stable event objects, and deduplicated by `eventId`. This prevents double-posting when reruns happen due to retries or partial export failures.

3) Event ingestion: webhook-like updates + idempotency

If your downstream expects push events, we can translate “polling exports” into webhook-style events. The connector stores a watermark per consentId so only new items are emitted.

Compliance & privacy

Regulatory context we design for

Deblock’s French authorization and AMF PSAN approval create strong expectations for responsible handling of financial and personal data. For integration delivery, we design around:

• GDPR (Regulation (EU) 2016/679) for lawful processing, data minimization, and user rights management.
• PSD2 (Directive (EU) 2015/2366) as a consent-based access reference model for open banking-style data retrieval.
• AMLD5 (Directive (EU) 2018/843) concepts for transaction-related risk controls and auditability expectations.

Our integration packages include guidance for secure token storage, explicit consent scopes, and retention boundaries so engineering teams can pass internal security reviews with clear documentation.

Data flow / architecture

A simple and auditable pipeline we use for Deblock is:

• Client App (or integration operator) requests consent + defines desired scopes and ranges.
• Deblock Adapter performs authorized export/polling and produces raw OpenData records.
• Normalization Layer converts records into OpenFinance objects (ledger events, trades, transfer statuses).
• Storage + Output APIs exposes JSON/CSV bundles plus webhook-like events with idempotency keys.

Market positioning & user profile

Deblock is positioned as a consumer-first EU fintech: users who want a traditional account experience (salary, IBAN, SEPA transfers, Visa debit cards) while also operating a self-custodial crypto wallet (BTC, Solana, USDC swaps and transfers). Research sources describe availability across Europe, with a focus on mobile-first experiences (iOS and Android).

Typical integration buyers are B2B product teams building accounting portals, tax/reporting assistants, portfolio dashboards, and payment reconciliation tools for individuals or small businesses. They often rely on consent patterns similar to OpenBanking concepts and may use ecosystem components such as Tink-style AIS consent workflows as a reference when designing secure data access.

In the same category, products like Revolut and Lydia are often referenced by users exploring “fiat + crypto” lifestyles. Our work keeps the focus on Deblock’s own regulated capabilities and the integration outputs your systems require.

Integration landscape (why OpenData/OpenFinance matters)

Finance platforms often need a consistent “ledger event” model that can power budgeting, reconciliation, and statement-backed reporting. By exposing Deblock’s exported records as OpenData and then projecting them into OpenFinance objects, your pipeline stays auditable and easier to maintain across releases.

We also structure the integration so it fits consent-based access models commonly referenced in open banking deployments, reducing the gap between app journeys and downstream engineering contracts.
