Tokeflow is an API-first, white-label payment orchestration platform that lets software companies, marketplaces and platforms embed payments as a native feature of their own product โ€” under their own brand, dashboard and domain. Instead of locking you into a single processor, Tokeflow sits as an intelligent layer in front of multiple PSPs. Each merchant connects their own provider accounts (Stripe, Pagar.me, Mercado Pago and more), and every transaction is routed to the best provider by country, currency, payment method, card brand, amount or custom rules โ€” with automatic cascading fallback to recover declines and lift approval rates. At its core is a proprietary recurring billing engine built for real-world complexity: subscriptions, trials, upgrades and downgrades with proration, installment plans, configurable dunning and retries, network-token credential management and end-of-month-safe scheduling. Cards and PIX work out of the box, on a single canonical transaction model that keeps reconciliation and auditing simple. Tokeflow is multi-tenant by design: an Organization governs the environment while each Merchant owns its connectors, routing and operations โ€” so one platform can serve many sub-merchants, each configured differently. A self-service Customer Portal lets end-customers manage their own subscriptions and payment methods. PCI and security complexity are absorbed by the platform, keeping merchants in the lightest possible compliance scope while they retain full technical autonomy โ€” no merchant-of-record, no vendor lock-in. Inbound and outbound webhooks, strict idempotency and a complete append-only audit trail keep the entire payment flow reliable, observable and predictable. Offer payments as if the technology were your own โ€” Tokeflow is the engine underneath.

assertpy features and specs

  • Fluent API
    Assertpy offers a fluent API that makes assertions more readable and expressive, enabling developers to write assertions in a natural language style that is easy to understand.
  • Chainable Assertions
    It allows for chainable assertions, enabling multiple checks to be performed in a single line of code, thereby reducing verbosity and enhancing clarity.
  • Comprehensive Assertion Methods
    The library provides a wide range of built-in assertion methods, catering to various types of data validations, such as checking for size, type, value, and more.
  • Extensibility
    Assertpy supports extending its functionality by defining custom assertions, allowing developers to tailor it to their specific needs.
  • Pythonic
    Designed with Pythonic principles in mind, Assertpy fits seamlessly into Python projects, enabling idiomatic and consistent code style.

Possible disadvantages of assertpy

  • Learning Curve
    Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
  • Limited by Python Version
    The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
  • Performance Overhead
    The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
  • Less Community Support
    Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
  • Dependency Management
    Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.

Questions & Answers

As answered by people managing Tokeflow and assertpy.

What makes your product unique?

Tokeflow's answer

Most products in this space are one thing: a routing layer, or a billing tool, or a hosted checkout. Tokeflow combines multi-PSP orchestration, a serious proprietary recurring-billing engine, and true architecture-level white-labeling in a single platform โ€” designed from the ground up to disappear inside another company's product as if it were their own technology. Each sub-merchant keeps its own PSP accounts, routing strategy and billing rules, and the platform absorbs the PCI and infrastructure complexity so its customers stay in the simplest compliance scope. No merchant-of-record, no vendor lock-in.

Why should a person choose your product over its competitors?

Tokeflow's answer

Because Tokeflow is built for companies that want to own their payment relationships and their brand, not rent them. Competitors usually force a trade-off: smart routing but no real recurring billing, or strong billing tied to a single processor, or an orchestrator that puts its own brand in front of your customers. Tokeflow delivers multi-PSP routing with fallback, a full recurring-billing engine, deep white-label and PCI-scope reduction together โ€” with each merchant keeping its own PSP accounts and zero lock-in. It's API-first, so it embeds cleanly into an existing product, with first-class support for cards and PIX for Latin American volume.

How would you describe the primary audience of your product?

Tokeflow's answer

Software platforms, SaaS products, marketplaces and integrators that want to offer payments as a native, branded feature to their own merchants or users โ€” without becoming a PSP or a merchant-of-record themselves. They typically have recurring revenue (subscriptions, installments) and multi-PSP needs, often operate in or are expanding into Latin America, and want orchestration, recurring billing and PCI-scope reduction without building it in-house. The buyer is usually technical โ€” a CTO, head of payments or platform engineering lead.

What's the story behind your product?

Tokeflow's answer

Tokeflow was created by a founder-engineer who kept hitting the same wall: every company that sells online eventually has to wrestle with multiple PSPs, local payment methods, recurring-billing edge cases, failed-payment recovery and PCI compliance โ€” and the existing orchestration tools either weren't truly white-label or didn't take recurring billing seriously. So the goal became building the layer that should have existed: clean enough to live invisibly inside someone else's product, opinionated enough to handle the hard parts of subscriptions and routing, and disciplined about absorbing the compliance complexity that scares most teams away. The result is a platform that lets any company offer payments as if the technology were its own.

Which are the primary technologies used for building your product?

Tokeflow's answer

Tokeflow's backend runs on Node.js and TypeScript with the NestJS framework, organized as a modular, domain-driven architecture (tenancy, routing, transactions, billing, webhooks). Data is stored in PostgreSQL, with asynchronous processing and webhook handling powered by a managed message queue and worker services. The dashboards and Customer Portal are built with Next.js, React, TypeScript and Tailwind CSS. Everything runs on AWS cloud infrastructure behind a CDN/WAF edge layer. Sensitive card data is handled via network tokenization and an isolated card-data environment, so raw card numbers never touch Tokeflow's own backend โ€” which is what keeps merchants in a minimized PCI scope.

Who are some of the biggest customers of your product?

Tokeflow's answer

Tokeflow is an early-stage platform currently onboarding its first merchants, so it isn't publicly naming customers yet. Reference accounts will be shared as the rollout progresses.
