Technology

Flexible integration, designed around your architecture

Slate is built to integrate into different institutional environments, from deeply embedded backend architectures to rapid go-to-market models.

Whether your priority is full technical control, accelerated deployment, or a phased evolution over time, Slate supports multiple integration approaches on the same modular platform.

For institutions that require deep architectural integration and full control over frontend and orchestration.

For a seamless, bank-branded investment experience embedded directly into your existing channels.

For launching a complete, fully branded investment proposition with maximum speed and reduced engineering effort.

Each model is built on the same institutional-grade infrastructure, allowing you to adapt your integration strategy over time without replatforming.

API-based integration

(backend-to-backend)

Bank integrates directly with Slate’s platform through secure, institutional-grade APIs and consumes investment capabilities as backend services inside the institution’s own channels and internal systems.

  • Entity retains full control of the frontend, UX and orchestration of customer journeys and internal workflows.

  • Trading/OMS (order submit/modify/cancel and lifecycle), portfolios/positions/valuation, cash movements, post-trade events (confirmations/settlement status), reporting datasets/feeds, and operational/audit data as required.

  • REST for synchronous journeys (e.g., placing an order, retrieving a portfolio), plus webhooks/event notifications and optional batch exports for asynchronous updates and reconciliation needs.

Key benefits

Deep integration into the bank’s architecture, maximum data and workflow control, and long-term flexibility. Your institution integrates once to stable domain APIs while Slate absorbs provider-specific differences via its multi-broker/multi-custodian abstraction layer.

App-in-App integration

Slate’s investment experience is embedded within your institution’s mobile and/or web applications using a secure App-in-App or WebView approach, providing a seamless bank-branded user experience.

  • Slate delivers and operates the embedded investment UI and end-to-end flows (e.g., discovery, trading journeys, portfolio views), while your bank hosts it inside its app container.

  • Fully institution-branded and transparent to the end customer; consistent look-and-feel can be aligned to your design requirements.


  • Slate manages the embedded workflows and related backend services; you retain governance and can keep control of adjacent services (e.g., identity, customer communications) based on the agreed setup.

Key benefits

Faster time-to-market compared to building full journeys natively via APIs, reduced channel build effort for your bank and a pragmatic path to evolve toward deeper API or hybrid integration over time.

White-label solution

Slate provides a fully white-labelled investment solution from a technology perspective, including frontend components, backend services and operational tooling, branded under your company’s identity.

  • White-labelled frontend + core investment backend (trading, portfolios, reporting, operational controls) + operational tooling for backoffice workflows.

  • Suitable for rapid market rollout and for phased evolution. Your institution can start with a full white-label and progressively move specific capabilities to direct API consumption if desired.

  • Uses the same modular platform and integration layer, enabling your bank to configure products, providers, and workflows without replatforming.

Key benefits

Maximum speed for launching a complete proposition, reduced engineering burden on your bank for day-1 scope, and a controlled transition path to deeper integration while remaining fully institution-branded.
