The short version

  • Only AWS API Gateway has a free tier, so it costs nothing to try first.
  • Each has a real cost: AWS API Gateway rEST APIs cost $3.50 per million calls against $1.00 for HTTP APIs, so the older and more featureful type is three and a half times dearer; Fintecture coverage and merchant adoption are heavily French, so a European rollout means strong performance in one market and a thin experience in the rest.
  • They diverge on capability: AWS API Gateway covers REST APIs, Fintecture covers Invoice payment links.
  • 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.

AWS API Gateway

  • REST APIs cost $3.50 per million calls against $1.00 for HTTP APIs, so the older and more featureful type is three and a half times dearer
  • Data transfer out is charged at $0.09 per GB on top of request pricing
  • WebSocket APIs bill connection minutes as well as messages, at $0.25 per million minutes
  • Private APIs avoid data transfer charges but incur AWS PrivateLink costs instead
  • The developer portal is $125 a month, with additional portal products at $12.50 each
  • The free tier lasts 12 months rather than being ongoing

Fintecture

  • Coverage and merchant adoption are heavily French, so a European rollout means strong performance in one market and a thin experience in the rest.
  • Deferred and instalment payment relies on a financing partner that sets acceptance criteria, so your business customers can be declined for reasons you cannot see or influence.
  • As a payment initiator rather than an acquirer, Fintecture leaves refunds, disputes and settlement structure with the supplier, and there is no chargeback framework at all.
  • Business to business bank payments require the payer to authenticate with their bank, and corporate banking authentication with dual approval is materially clunkier than consumer app redirects, which hurts conversion on large invoices.
  • It is a smaller supplier than the pan European open banking firms, so bank API breakage outside France may take longer to fix and support depth is a legitimate procurement concern.
