The short version

  • Only Microsoft Azure API Management has a free tier, so it costs nothing to try first.
  • Each has a real cost: Microsoft Azure API Management prices are not shown on the pricing page itself; every tier renders as a placeholder and routes to the calculator or sales; Highnote card issuing requires a sponsor bank, and that bank sets programme approval, compliance obligations and often minimum volumes, so a small programme can be rejected regardless of technical fit.
  • They diverge on capability: Microsoft Azure API Management covers API Gateway, Highnote covers Card issuing.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Microsoft Azure API Management

  • Prices are not shown on the pricing page itself; every tier renders as a placeholder and routes to the calculator or sales
  • Two parallel generations of tiers, classic and v2, so the choice is which lineage before which size
  • The Developer tier is explicitly not for production
  • Self-hosted gateways and workspace gateways are charged separately from the service

Highnote

  • Card issuing requires a sponsor bank, and that bank sets programme approval, compliance obligations and often minimum volumes, so a small programme can be rejected regardless of technical fit.
  • Pricing is entirely quoted, including platform fees, per active card charges and monthly minimums that do not appear on the website, so the true cost per card is only visible late in a sales process.
  • Interchange sharing is the real revenue model for most customers, and the split is negotiated, capped for regulated debit under the Durbin amendment and sensitive to your spend mix, so revenue projections built on headline interchange rates overstate income.
  • Running issuing and acquiring with one provider concentrates risk: an outage or a compliance action affects both money in and money out at the same time.
  • Highnote is a younger company than the established issuer processors, so long term programme continuity, network certifications in new geographies and international coverage are thinner than the incumbent alternatives.
