Developer & API docs

Build on FYNXT and keep the boundaries clear.

Technical guidance for APIs, events, webhooks, widgets and integration patterns across the FYNXT platform. Reference documentation comes with API access.

Building blocks

Four ways to build on FYNXT.

Use the approach that fits the job: call a service, listen for a change, embed an experience or reuse a proven connector.

01

APIs

Work with platform and solution services from your own applications: clients, accounts, payments, partners and more.

02

Events and webhooks

React to meaningful operating changes, such as an approved application or a completed payment, instead of polling for them.

03

Widgets

Embed focused FYNXT experiences, such as onboarding steps or account views, in the channels you already run.

04

SDKs and connectors

Use established connectors for trading platforms and providers, and SDK patterns for your own integrations.

Integration patterns

Decide who owns each record.

Before the first call, agree which system is the source of truth for each record and which one orchestrates the journey. A typical split looks like this; your architecture decides.

FYNXT typically orchestrates

Journeys and rules

  • Client onboarding and verification journeys
  • Workflows, approvals and service cases
  • Partner programmes and commission rules
  • Payment routing across providers
Your estate typically keeps

Systems of record

  • Core banking or general ledger
  • Trading platforms and their accounts
  • Data warehouse and group reporting
  • Provider contracts you already hold
How access works

From request to production.

Access starts with a conversation about what you want to build, so the documentation and environments match the scope.

  1. 01

    Request access

    Tell us what you want to connect and why.

  2. 02

    Agree the scope

    Decide the records, events and environments involved.

  3. 03

    Build and test

    Develop against a non-production environment with the documentation for your scope.

  4. 04

    Go live

    Promote the integration under the same change controls as the rest of the platform.

What good looks like

Integrations that stay easy to change.

What to aim for when you build on FYNXT.

Clear ownership of every record

Each record has one source of truth, and every integration knows which one.

Integrations that follow the journey

Events connect systems at the moments that matter to the client and the operator.

Change under the same controls

Integration changes are approved and traced like any other configuration change.
