KPN PIM ID API
KPN PiM ID generates tamper-proof, company-specific encrypted QR codes from validated customer data (POST /image on https://api-prd.kpn.com/kpn/qrcodegenerator). The codes are embedded in surfaces such as login pages and scanned with the PiM mobile application to authenticate a customer. Authentication is OAuth 2.0 client_id/client_secret. No public OpenAPI definition is published for PiM ID on KPN's SwaggerHub organisation as of the harvest date.
