Systems That Talk to Each Other

Software rarely lives alone. Orders come from a store, invoices go to accounting, customers arrive from a form, and stock sits in a system nobody wants to replace. APIs are the contracts between those tools, and when a contract is vague the data arrives late, partial, or not at all.

Aurevo System designs and builds both sides of that exchange: documented endpoints your team can depend on, and the connections that carry records between the tools you keep. Work starts from the data that must move and the moments at which it has to be correct.

Problems We Solve

Where integrations break down — and what a properly built interface changes.

01

Copy-Paste Between Two Systems

Staff transfer records by hand because the tools do not speak to each other. An integration moves the record at the moment it changes.

02

Undocumented Endpoints

Nobody outside the original developer knows what the interface expects, so every change risks breaking callers. Contracts, versions, and examples are written down.

03

Sync Failures Nobody Notices

A connection drops overnight and the problem surfaces as customer complaints. Monitoring, retries, and alerts catch it while it is still small.

04

The Same Logic Built Twice

Each new tool gets its own bespoke script until the rules are duplicated and inconsistent. Shared endpoints keep one implementation everyone calls.

05

Data Matching by Guesswork

Records are merged on names that differ between systems, creating duplicates and wrong links. Identifiers and mapping rules are defined in the contract.

06

A Third Party Changes Without Warning

An external service alters its API and the integration fails at the worst moment. Version pinning, tolerant parsing, and alerting keep the shock small.

Interfaces and Connections

REST API Design

Endpoints shaped around the resources your business actually uses, with predictable naming, pagination, and consistent error responses.

Authentication & Access

API keys, tokens, and scoped permissions so each integration can see and change only what it should.

System-to-System Integration

Store, accounting, CRM, and internal tools connected so a record entered once appears everywhere it is needed.

Webhooks & Event Flow

Push-based notifications so downstream systems react the moment something happens instead of polling for it.

Data Mapping & Validation

Field mapping, formatting rules, and checks at the boundary, so bad input is rejected where it enters rather than discovered later.

Documentation & Sandbox

Written reference material and a test environment, so another developer can integrate without asking us for answers.

Integrations Built to Be Trusted

Contracts, error handling, and monitoring settled before the first record moves.

01

Contract First

Request, response, and failure behaviour are agreed and documented before code, so both sides build against the same promise.

02

Designed to Fail Loudly

Retries, idempotent operations, and alerts mean a broken connection is reported, not discovered by a customer.

03

One Source per Fact

Each system owns specific data and the others reference it, which stops two records quietly disagreeing.

04

Security at the Boundary

Scoped credentials, validated input, and encrypted transport are part of every interface rather than a later hardening pass.

05

Change Without Breakage

Versioning and backward-compatible changes let integrations evolve while existing callers keep working.

06

You Own the Work

Code, credentials, and accounts stay in your name, with documentation handed over so your team can extend the interfaces.

From Two Systems to One Flow

01

Discovery & Data Mapping

We identify which records move, where they originate, and which system owns each fact, then agree the integration points.

02

Contract & Error Design

Endpoints, payloads, and failure behaviour documented so both sides know exactly what to expect.

03

Build in Short Cycles

Endpoints and connections delivered incrementally with working examples you can test against a sandbox.

04

Testing Against Real Data

Volumes, edge cases, malformed input, and partial failures exercised before any live record is trusted to move.

05

Launch & Monitoring

Go live with logging and alerts in place, then documentation and handover for the team that maintains it.

Protocols and Platforms

Standard protocols and mainstream services — chosen for interoperability and long-term support.

What Connected Systems Give You

No Double Entry

A record typed once reaches every system that needs it, which removes the repeated admin and the errors that travel with it.

Faster New Integrations

Documented endpoints and a sandbox let the next connection be built in days rather than reverse-engineered for weeks.

Information When It Matters

Webhooks push updates the moment they happen, so decisions are made on current data instead of last night’s export.

Fewer Surprising Failures

Alerts, retries, and clear ownership turn a broken connection into a known ticket instead of an unexplained discrepancy.

Frequently Asked Questions

What does API development and integration include?

Designing and building the endpoints themselves, authentication and permissions, the connections between your tools, plus documentation and monitoring. Where a third-party service already offers an API, we connect to it rather than duplicating what it does.

How long does an integration project take?

A single connection between two well-behaved systems usually takes two to four weeks. Multiple systems, legacy software, or complex data mapping extend that, and we confirm a timeline after the data mapping stage.

Can you integrate with software that has no API?

Often, yes. Common options are file exports, database access where permitted, or a scheduled sync. We assess what the vendor allows and set out the trade-offs before committing to an approach.

Who owns the API and the data?

You do. Source code, repositories, credentials, and accounts remain in your name, with documentation and handover so your team can maintain and extend the interfaces independently.

Do you build the APIs as well as integrate with other people’s?

Yes, both. We design and document APIs for your own systems and applications, and we integrate with third-party services — payment providers, accounting, CRM, shipping, marketing platforms — through their published interfaces, handling authentication, rate limits, and their error responses.

How do you keep the connection secure?

Transport encryption, scoped credentials, and signed or token-based authentication are standard. Access is limited to what each integration needs, secrets stay out of source code, and logs record who changed what without exposing sensitive values.

How do you handle API rate limits when syncing large amounts of data?

We design the integration around each provider's published limits, batching records, spacing requests, and queuing work so a burst of activity does not trigger blocks. Where an API allows it, we sync incrementally so only changed records move rather than the whole dataset each time. Retries and backoff are built in, and anything that still fails is logged for review.

How do you test that the data moving between systems stays accurate?

Before launch we run a reconciliation check that compares totals and sample records on both sides, then repeat it after each change. Errors, duplicates, and mismatches are flagged automatically so they surface early instead of silently skewing a report. You receive the test results alongside the handover documentation.
