Use this tool to handle Spark authentication without writing any code. Everything runs in your browser, so your token and sign key never leave your machine. The tabs at the top cover the three operations the tool performs:
  • StartAuthentication: build or inspect the cipher and the TransactionSignature header for the StartAuthentication call, the integrator’s first request to open a transaction. The Auth and Legacy Auth (v1) sub-tabs cover the current and legacy signature flows.
  • StartSession: build or inspect the Cipher your server returns when Nayax sends a StartSession request to open a session.
  • Header Signature: generate the IntegratorId and TransactionSignature headers that authenticate a Spark API request.
