Future work

The upstream API also returns a single status message, indicating possible problems. This can be used as event to inform our internal downstream services more specifically:

{
  "Message": "",
  "AllGreen": true,
  "AllGreenMessage": "Momenteel zijn alle banken beschikbaar. U kunt betalen met iDEAL"
}

Failure situation:

{
  "Message": "Heeft u als ondernemer (webwinkel) een iDEAL-contract bij ING, dan kunt u geen iDEAL-betalingen laten doen.<br />Laat uw klanten het nogmaals proberen of bied een andere betaalmethode aan.",
  "AllGreen": false,
}
