Establish the connection via API (self-billing context)

Self-billing uses the same Agent interface (action-agent_ceg_mb) as delegated invoicing. The full description is in the delegated Establish the connection via API section: the XML and XSD and the cases after submission with the error list. This page covers what to keep in mind in the self-billing context.

What changes in self-billing?​

  • The technical XML and account-connection flow stay the same.
  • In the <cegMb> block you send the supplier's (your partner's) company data: it is their account that gets created or connected.
  • The <usrMb> user is the dedicated user of the buyer company; this user issues the self-billed invoices later.
  • The business rule changes: the buyer on the invoice is the same company as the delegate.
  1. Create or connect the supplier account via action-agent_ceg_mb, with an agreed <cegszamlaszamelotag> invoice prefix.
  2. Use a dedicated delegated login user (single-account access); otherwise logins fail with error 164.
  3. Wait for the supplier to take ownership and approve the connection.
  4. Issue the invoices from the supplier account, with the buyer set to your own company; see Issue invoices as self-biller.

The interface requires a licence; you can request access from customer support. Without the licence the call fails with error 137. General authentication details are in Authentication.
