Authentication
Authenticate with the Customer API using an API key in the XApiKey header. The key grants full access to all endpoints for your client account.
Getting Your API Key
Generate keys in the Creditor Portal → API Keys. You can create multiple keys (e.g., for different systems or team members).
Making Requests
Include your API key in every request:
curl https://customer-api.debitura.com/me \
-H "XApiKey: YOUR_API_KEY"
A successful response confirms your key is valid:
{
"id": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
"companyName": "Acme Corporation",
"companyRegistrationNumber": "12345678",
"country": "DK",
"officeEmail": "billing@acme.com"
}
