Banco Comercial Portugues API Access | open-banking.io

Bring Banco Comercial Portugues straight into your own software. With open-banking.io you can sync account details, balances and transaction history from this Portuguese bank through a single, standards-based API — no bespoke integration work, no bank-specific paperwork, and no eIDAS certificates to procure. Whether you are building bookkeeping tools, cash-flow dashboards or payment reconciliation, the same endpoints that serve 2,600+ European banks also serve Banco Comercial Portugues.

How to connect Banco Comercial Portugues

  1. Create an open-banking.io account and generate your API keys.
  2. Start an authorisation session, selecting Banco Comercial Portugues (BIC BCOMPTPL).
  3. Your customer is redirected to the bank to log in and approve access with their own credentials.
  4. Consent is confirmed and returned to your application.
  5. Query the account, balance and transaction endpoints — data flows in normalised JSON.

What data you can access

  • Accounts — identifiers, IBANs and account metadata across business and personal account types.
  • Balances — current and available figures, refreshed on demand.
  • Transactions — booked and pending entries with amounts, counterparties, dates and reference details.

Access is granted under the customer's explicit authorisation, valid for a maximum consent window of 180 days. After that, the account holder simply re-approves to keep the connection live. Because open-banking.io speaks the same PSD2 protocol everywhere, adding Banco Comercial Portugues alongside other institutions is a configuration change, not a new project.

Privacy by design

The platform is zero-knowledge: credentials are entered only at the bank, never with us, and the pipeline is certificate-free, so you skip the cost and delay of managing QWAC/QSEAL certificates. You get clean data; the sensitive parts stay between your customer and their bank.

Simple pricing

One flat subscription of roughly EUR 3/month covers API access — no per-call surprises and no separate licensing per bank.

FAQ

Which account types does Banco Comercial Portugues support?

Both business and personal accounts can be linked, so you can serve companies and individuals through the same integration.

How long does a single authorisation last?

Up to 180 days. When the window closes, the account holder re-approves access to continue syncing.

Do I need an eIDAS certificate to connect?

No. open-banking.io is certificate-free, so you can go live without procuring or maintaining QWAC/QSEAL certificates.
