How will you use the API?

The cooperation type depends only on how many companies you connect and who pays for them. Every type includes SAPI, Enterprise API and Connector at the same price. The application and agreement are currently completed in Slovak; your selection below is carried into the correct legally binding flow.

Not sure which type is yours? Answer a few questions.

How many companies will you connect through the API?

Four cooperation types

The customer pays

Direct customer

You use the API for one company of your own and pay its usage. You create the key in the company account under Nastavenia → API (Settings → API).

  1. Your company
  2. ePošťák

Example: a company sends its own invoices straight from its ERP.

  • one company of your own
  • key in Settings → API
  • no White Label

Several companies of your own under one key and one invoice: choose Managed integrator.

Each client company pays separately

Technical partner

You connect several companies with one key, but each company pays ePošťák itself under the price list. You do not pay for them.

  1. Each client
  2. ePošťák

Example: the basic invoicing program by SofCom connects the companies that use it.

  • clients pay ePošťák directly
  • the client confirms one link, no key to paste
  • also for clients receiving through another provider (sending only)
  • no consolidated integrator invoice
You pay for all companies

Managed integrator

You connect several companies with one key and pay for them together on one invoice. They can be companies of your group or your clients.

  1. Your companies
  2. You
  3. ePošťák

Example: a group of 70 project companies, or a service company that runs invoicing for its clients.

  • one API key for all companies
  • one consolidated invoice
  • the company confirms one link, no key to paste
The partner pays centrally

White Label

You provide the service under your own brand. The client selects you on the Financial Administration portal (vPDS) and has no ePošťák account or emails from us. You pay for all clients together.

  1. Clients
  2. Your brand
  3. ePošťák

Example: an ERP vendor offers an e-invoicing mailbox under its own name as part of its product.

  • your own brand
  • the client selects the partner in vPDS
  • no ePošťák account
  • not combined with the technical partner model

You apply as a managed integrator and choose White Label in the order.
