Connect ING to Hypamoon

Possible, with help from ING. The API is documented, but you cannot just create a key: access goes through ING first.

Possible

The check

Three questions about the API of ING, answered from its own docs.

Public API docs
Yes. The ING Developer Portal publishes get started guides and API documentation for the PSD2 APIs and the Premium APIs, such as the Real-time Account Reporting API, the Payment Request API and the Boekhoudkoppeling API. Read the docs
A key you create yourself
No. You create an account, a team and an application yourself, but every API subscription is subject to approval by ING, and some Premium APIs need a signed Open Banking agreement. PSD2 APIs need a licence as a third party provider and an eIDAS certificate. developer.ing.com
Versions or a changelog
Yes. ING announces breaking changes in advance on the portal, and Premium APIs come with an OpenAPI specification. developer.ing.com
How it signs in
OAuth 2.0 with client credentials or an authorization code flow, over mutual TLS with your own certificate; some APIs also need signed requests.
Webhooks
Not confirmed.
Hosting
Cloud
Condition
Every API subscription is approved by ING, and some Premium APIs need a signed Open Banking agreement. PSD2 APIs need a third party provider licence. Without that, read your ING accounts through a licensed aggregator such as Ponto Connect (https://documentation.isabel.eu/ponto-connect/2/products) or Enable Banking (https://enablebanking.com/docs/api/linked-accounts/), or import a CAMT.053 or MT940 export.

What you can build

See balances and incoming payments on your ING business accounts in your own dashboard and match them to open invoices, through an approved ING API or an aggregator.

Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. How adapters work

Good to know

  • ING signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for ING takes more work: ask your chat to check this first.
  • ING has PSD2 APIs for licensed providers and Premium APIs, such as Real-time Account Reporting for wholesale accounts and Payment Request for payment links. All use mutual TLS with your own certificate.

Try it in your chat

First get access from ING. Then fill in what to read and write, and send it.

The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.

Check if [software] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
