FAQs from Teams Who Own the Tech Stack

Is Sticky.io a headless CRM and revenue platform?

Yes — and that distinction matters.

Sticky.io operates as a headless CRM and payments platform, meaning we manage subscriptions, customers, transactions, offers, billing logic, and recovery — without dictating your frontend experience.

You maintain full control over:

  • Frontend frameworks (Next.js, React, custom apps, etc.)
  • CMS or ecommerce layer
  • Internal tooling
  • Data pipelines

Sticky.io acts as a revenue layer behind the scenes — structured, API-driven, and composable — so your architecture stays clean while payments and subscription logic scale with you.

If you're building a headless, composable, or hybrid commerce stack, Sticky.io fits naturally into that model.

Does Sticky.io offer open APIs, webhooks, and custom integrations?

Yes. Sticky.io is API-first.

Every core function — subscriptions, transactions, customer updates, retries, routing, lifecycle events — is exposed through REST APIs and webhooks.

That means you can:

  • Trigger custom workflows on payment events
  • Sync subscription state with internal systems
  • Feed transaction data into BI tools
  • Automate lifecycle events
  • Build custom dashboards or reporting layers

We don’t hide functionality behind UI constraints. If it happens in Sticky.io, it’s accessible programmatically.

 

How does Sticky.io integrate with existing ecommerce platforms and tools?

Sticky.io integrates in two primary ways:

  1. Native integrations and pre-built connectors ( 500+ ecommerce platforms, gateways, fraud tools, analytics systems, etc.)
  2. API and webhook-based custom integrations

You can use Sticky.io as:

  • A subscription and billing engine behind Shopify or other storefronts
  • A headless CRM connected to custom frontend experiences
  • A payments orchestration layer across multiple gateways
  • A data source feeding internal dashboards and finance systems

No forced replatform. No rigid implementation path. Integration is incremental and adaptable to your architecture.

Can Sticky.io work with our existing payment gateways and processors?

Yes — and that’s often the starting point.

Sticky.io supports 160+ gateways and processors, allowing you to maintain existing acquiring relationships while adding:

  • Smart routing and cascading
  • AI-powered retry logic
  • Multi-MID support
  • Recovery optimization
  • Fraud and chargeback workflows

You don’t lose control of your payments stack. You gain intelligence across it.

If you require a specific gateway or regional processor, our team can evaluate support and integration paths.

What kind of reporting and analytics does Sticky.io provide?

Sticky.io provides structured reporting across:

  • Offer performance
  • Campaign adoption rates
  • Checkout conversion rates
  • Affiliate revenue
  • Subscription renewals and upsells
  • Approval and decline rates
  • Retry success
  • Recovery lift
  • Churn trends
  • Cohort behavior
  • MID and gateway performance

Data is accessible via:

  • Real-time dashboards
  • Exportable reports
  • API access for BI ingestion

This makes it suitable for finance, payments operations, RevOps, and data teams who require clean, queryable revenue data — not just surface-level metrics.

Is Sticky.io easy to implement for technical teams?

Implementation is designed to align with modern engineering workflows.

Most teams integrate via:

  • REST APIs
  • Webhooks
  • Gateway connections
  • Authentication keys
  • Standardized data models

Because Sticky.io does not require frontend replacement, teams can integrate incrementally — starting with payment orchestration or recovery before expanding into CRM or subscription logic.

Our solutions architecture team supports implementation to reduce risk and ensure alignment with your internal systems.

Can Sticky.io replace custom-built subscription or payment logic?

In many cases, yes.

Many teams initially build custom retry logic, routing rules, and subscription workflows internally. Over time, that logic becomes complex, brittle, and expensive to maintain.

Sticky.io replaces:

  • Homegrown dunning systems
  • Hardcoded gateway routing
  • Manual retry scheduling
  • Patchwork fraud rules
  • Disconnected subscription tracking

You reduce maintenance overhead while gaining enterprise-grade payment intelligence.

Is Sticky.io built for enterprise scale?

Yes.

Sticky.io processes $12B+ in annual transaction volume and supports 72M+ subscriptions across industries. The infrastructure is designed for:

  • High transaction throughput
  • Multi-region routing
  • Complex subscription models
  • Multi-MID architectures
  • Compliance-aware workflows

This isn’t a lightweight plugin. It’s revenue infrastructure.

Built to Fit Your Tech Stack — Now and as You Scale

Sticky.io is built to support modern commerce architectures — giving your team the flexibility to integrate, scale, and evolve without introducing unnecessary complexity or technical debt.
