API Integrations

API integration services that keep your systems in sync.

Connect your CRM, online store, messaging apps, ad platforms and spreadsheets so data moves between them on its own, and lands in one place when you need the full picture.

We build system-to-system integrations and data sync that map fields between systems, agree which one holds the truth and handle failures, so records stay consistent without staff re-entering them.

  • Scoped, encrypted credentials
  • Failed calls retried, then flagged
  • A source of truth for each field

No upfront consultation fee. Free discovery and a free tailored proposal.

The challenge

Your systems have the data. They just don't share it.

When systems don't talk to each other, people become the integration: exporting, re-keying and reconciling between tools.

What we build

The parts of a reliable integration.

We start with a scoping checklist: API access, write permissions, source of truth, field mapping, update frequency, conflict rules and rollback.

01

API connections

Connections to CRM, e-commerce, messaging, marketing and ERP APIs, built against documented endpoints with each provider's recommended authentication.

02

Webhooks and events

Event triggers with signature checks, so a change in one system updates the others soon after it happens, and failures are flagged.

03

Data mapping

Field-level mapping between mismatched systems, with formats, units, codes and IDs normalised before anything is written.

04

Two-way sync

One-way or two-way sync with a source of truth for each field, duplicate checks and conflict rules agreed up front.

05

Custom endpoints

Your own authenticated REST or GraphQL endpoints, with rate limits and versioned documentation, when other systems need to reach yours.

06

Middleware and no-API routes

Middleware that links several systems, and fallback routes where there's no API: official exports, file exchange or a manual checkpoint.

How a record moves between systems.

Mapping rules move the data the same way every time. AI helps only where matching needs judgement, and records that don't fit the rules are held for a person.

Systems we connect

Across the systems your business runs on.

Most integrations link two or three systems. Some run through middleware that keeps several in step.

  • Zoho
E-commerce, payments and marketing
  • Shopify
  • WooCommerce
  • Stripe
  • Meta

ERP, finance and operations
  • SAP
  • Xero
  • QuickBooks
  • Google Sheets

  • Internal apps
  • Custom APIs

What's possible depends on each system's API, your licence and permissions, and sometimes vendor approval. Third-party API fees are separate from implementation.

Reliability and security

Integrations you can audit and recover.

An integration writes to your records, so security and failure handling are agreed before go-live. REST, GraphQL, OAuth and middleware are the tools; consistent records are the goal.

Tokens and access
OAuth tokens or API keys kept in encrypted secrets and refreshed as needed, with least-privilege access to each system.
Validation and idempotency
Records are checked before they're written, and idempotency keys stop a retry from creating duplicates.
Retries and rate limits
Failed calls back off and retry within each API's rate limits, then alert a named person.
Logs and access control
Every call is logged so a failed sync can be traced and replayed. Data handling, AI providers and hosting are confirmed per project.

Integrations running for clients today, plus solution showcases that connect stores, CRMs, messaging, ad platforms, suppliers and reporting dashboards.

How we work

From separate systems to one reliable sync.

  1. 01

    Access and data review

    We check each system's API, access rights and licence terms, and look at sample records from both sides.

  2. 02

    Mapping and rules

    We agree the field mapping, the source of truth, conflict rules and what happens when a record fails.

  3. 03

    Build and test

    We build against a test environment where one exists, and test with real, incomplete and duplicate records.

  4. 04

    Go live and monitor

    We switch on with logging and alerts, and hand over the mapping documentation.

Every project has an agreed scope and acceptance criteria before the build starts.

Project scope

Scoped around your systems.

Every integration depends on the systems at each end and what their APIs allow. These factors shape the scope.

Number of systems
A single two-system link, or middleware connecting several systems.
API quality and access
Documented APIs move fast. Legacy or undocumented endpoints take longer.
Data mapping
Matching fields, or mismatched schemas with transforms and de-duplication.
Sync direction and volume
One-way and low volume, or near real-time two-way sync with conflict rules.
Auth and compliance
Custom OAuth, IP allow-listing or regulated data add security work.
Vendor terms
API add-ons, licences or vendor approval. Third-party API fees are separate.
FAQ

API integration questions.

Straight answers about scope, data, ownership and support. Can’t find yours? Ask us directly below.

Which systems and third-party APIs can you integrate?

Most systems with an accessible API or webhook. Common ones include CRMs like HubSpot and Salesforce, ERPs and finance tools like SAP, QuickBooks and Xero, e-commerce platforms like Shopify, payment systems like Stripe, and databases like PostgreSQL and MySQL. If a system exposes a REST or GraphQL API and grants the access we need, we can usually connect it. Rate limits, licensing and vendor approval can affect what is possible, and some vendors require you to enable API access or approve the integration first.

What if a system has no API?

There are often other routes: webhooks, official export and import files, a database-level connection the vendor permits, approved middleware such as Zapier or Make, or a manual checkpoint in the process. Any route must be allowed by the vendor's terms and your licence. In scoping we confirm the most stable option before committing to it. Sometimes the honest answer is that a step stays manual.

Can you integrate legacy or on-premise systems?

Often, yes. Older systems may offer SOAP services, a local database the vendor allows us to read, scheduled export files or a connector that runs inside your network. We check what's available and permitted, then choose the route that will hold up, and agree how the connection is secured.

Can you set up two-way sync without duplicates or conflicts?

Yes, with rules agreed up front. We define a field mapping and a source of truth for each field, for example the CRM wins on contact details. Unique IDs, idempotency keys and de-duplication rules stop the same event writing twice, as far as each system allows, and reconciliation checks flag mismatches for a person to resolve.

What happens when an integration fails or a third-party API changes?

Failed calls retry with backoff, then alert a named person, and runs are logged so a failed sync can be replayed. Vendors deprecate endpoints and change versions, so we add monitoring that flags failed calls or schema changes early. With a maintenance plan we update the integration when an API version is retired, and without one we hand over documentation so your team can maintain it.

How do you handle API authentication and data security?

We use each provider's recommended authentication, such as OAuth 2.0, API keys or signed tokens, and store credentials in encrypted secrets rather than in code. Traffic runs over HTTPS, webhook payloads are signature-verified, access is scoped to the minimum permissions needed, and sensitive write actions can wait for a person to approve. Data handling, AI providers and hosting are confirmed per project.

Do you build against REST or GraphQL APIs?

Both, plus SOAP and webhook-based endpoints where a vendor still uses them. We choose per integration: REST for most CRM, ERP and SaaS APIs, GraphQL where a platform offers it and we need to fetch related data in one call. We test the endpoints we use in Postman before wiring them into your workflow.

How long does an API integration project take?

A single, well-documented two-system integration is the quickest to deliver. Multi-system middleware with custom data mapping, complex auth or ERP endpoints takes longer. After a free discovery consultation we prepare a tailored initial plan and proposal with a timeline and a private quote before any build starts.

Who owns the integration code and credentials after handover?

You own the bespoke integration deliverables built for your project under our agreement, including the workflows, custom middleware code and data-mapping documentation we hand over. Integrations are built in your accounts and connect through your own API credentials. Framworq keeps its pre-existing tools and reusable components, with the rights your team needs to use the system.
