API & system integrations

Make the systems that hold related information talk to each other, reliably and in one direction of truth.

The problem this solves

Your CRM, finance system, support desk and internal tools each hold part of the same picture. Without a connection between them, somebody re-types data and something is always out of date.

What the work involves

  • Establish which system owns which piece of information, so the sync has a direction.
  • Build the integration against real APIs, with retries and failure handling rather than a happy path.
  • Normalize the data in between, where the two systems disagree about format.
  • Add visibility so a broken sync is noticed before a customer notices.

What you end up with

  • Working integrations between the systems you named.
  • Documented field mapping and direction of truth.
  • Failure handling and alerting, not a silent script.

A good fit if

  • Somebody copies data between two tools every week.
  • A previous integration broke and nobody noticed for days.
  • You need a reusable data layer rather than another one-off script.

Pricing

Clear starting points. Custom scopes.

MessyOrg publishes starting points so organizations can understand the approximate level of investment before beginning a conversation. Final scope and investment are determined after we understand the problem, integrations, complexity, security requirements, timeline and desired outcome.

How we engineer it

Practices we use at every stage.

The same practices we use on our own internal builds, following the six stages of how we work. Highlighted stages matter most for this service.

  1. 01 Discover

    • Mapping existing tools, data and manual steps before proposing changes
    • Writing the problem down in plain language before choosing technology
  2. 02 Design

    • Planning data, user roles and permissions up front
    • Designing screens that work on phones as well as desktops
  3. 03 Build

    Key stage
    • Secure sign-in with role-based access
    • Database rules that keep each customer's records private
    • Connecting payments, email and outside services
  4. 04 Verify

    • Automated tests for pricing, permissions and key workflows
    • Security and production-readiness reviews before launch
    • Payments tested in test mode before going live
  5. 05 Launch

    • Custom domains, page titles and search basics set up
    • Written handoff notes and walkthroughs for your team
  6. 06 Care

    • Usage limits and spending caps on AI features
    • Error monitoring and a clear process for fixes
