Reference Specifications

Third-party reference documentation used by Via One integrators.

These are upstream provider specifications, not Via One docs — but they're collected here because integrators frequently need them for protocol-level work.

Telefónica México

  • Telefónica — ISO8583 Transactionality — full ISO8583 protocol spec used by TEMM (the production endpoint at 10.225.236.72:7903 and cert at 10.225.244.79:7903)
  • Telefónica — Especificaciones Genéricas V5.3 — generic specs for Telefónica integration
  • Telefónica TFMX — Web Service Recharge Specification — SOAP-based recharge endpoint specification

Servipagos VZ (Venezuelan bill payment)

  • Servipagos — Manual Operador App — operator-facing app manual (Spanish)
  • Servipagos — Manual Backoffice Comercio — commerce backoffice manual (Spanish)
  • Servipagos — Manual Administrador App — admin app manual (Spanish)

Coverage notes

These reference docs are provided as-is by the upstream providers. They cover the wire-level protocols, error codes, and integration steps from the provider's perspective.

For Via One-specific operations on top of these protocols (cert mode, wire SKU translation, idempotency, retry behavior), see:

Where to find the PDFs

The original PDF files are co-located with this documentation hub. They are also available in the source folder at ~/Downloads/Via One Manuals/Reference Specs/ on the canonical operator machine.

Direct downloads are not enabled in this hub for the reference specs, since they belong to the upstream providers and have their own distribution restrictions.
