I am trying to move our Bunq integration to production.
I followed the steps described here: https://beta.doc.bunq.com/psd2/connect-as-a-psd2-service-provider
I make a call to /installation, then supply my QSeal certificate + CA certificate chain in my call to /payment-service-provider-credential.
However, when I call /payment-service-provider-credential, I am getting the following error message in the response body:
“error_description”: “Certificate root is not trusted.“,
“error_description_translated”: “Certificate root is not trusted.”
As the message suggests, I suppose this means Bunq does not trust my root certificate? Would this be an oversight on your part or is something wrong in my request? The root CA is Multicert, and I have successfully been using it for our other bank integrations.
