API & System Integrations

Make your systems work together.

AtomoWeb connects business applications, APIs and data sources so information can move reliably between the systems your team already uses.

REST APIs Webhooks Data Sync CRM & Business Systems Payments Background Jobs Custom Middleware

Less copying data. Fewer disconnected workflows. More reliable systems.

Common Integration Problems

When systems work individually, but not together.

Most integration work starts with a workflow that depends on someone moving information by hand.

⌨️

Repeated data entry

  • Copying customer information
  • Entering orders twice
  • Updating statuses manually
  • Duplicating records across systems
📤

Manual imports and exports

  • CSV exports and spreadsheet uploads
  • Recurring file transfers
  • Scheduled reports assembled by hand
🧩

Different data models

  • Mismatched IDs
  • Different field names
  • Different status values
  • Inconsistent formats
🧵

Fragile existing integrations

  • Undocumented scripts
  • Failures that happen silently
  • Missing retries
  • Expired credentials
🐌

Slow operational workflows

  • Staff waiting for information
  • Manual approvals
  • Delayed updates
  • Processes spanning several tools
🔍

Missing visibility

  • No integration status
  • No error history
  • No audit trail
  • No signal when a sync fails
Before / After

From manual handoffs to connected systems.

The same order, handled once. Each step runs in the system that owns it.

Before — Manual Handoffs

Customer submits order
↓
Employee copies data to internal system
↓
Payment status checked manually
↓
Spreadsheet updated
↓
Another employee updates the CRM
↓
Customer receives status later

After — Connected Systems

Customer submits order
↓
Application validates the request
↓
Payment system sends status through API or webhook
↓
Internal records update automatically
↓
CRM receives the relevant data
↓
Customer status stays synchronized

The goal is not simply to move data between applications. A reliable integration also handles validation, failures, retries, permissions and exceptions.

What We Integrate

Connect the systems your business depends on.

Most projects touch several of these. We start from the data and the workflow, then choose the connection method.

Production Integrations

Production integrations need more than a successful request.

Connecting an endpoint is usually the easy part. Reliable integrations need to account for failures, duplicate events, authentication, unexpected data and changing external systems.

🔑

Authentication

  • API keys and OAuth
  • Tokens and credential rotation
  • Permission scopes
✅

Validation

  • Required fields and data types
  • Business rules
  • Source verification
  • Malformed payloads
🚨

Error handling

  • Timeouts and service outages
  • Invalid responses
  • Partial failures
  • Actionable error messages
🔁

Retries & queues

  • Background jobs
  • Controlled retries
  • Delayed processing
  • Rate limits and temporary failures
🛑

Idempotency & duplicate protection

Prevent the same event from creating duplicate orders, payments or records when systems retry requests.

📊

Logging & monitoring

  • Request history
  • Error logs and sync status
  • Operational visibility
  • Faster troubleshooting
Integration Architecture

Direct connection, middleware or API layer, depending on the system.

The architecture should match the business problem. We do not add middleware or complexity when a direct integration is sufficient.

🔗

Direct API integration

Appropriate when systems expose stable APIs, the workflow is straightforward and transformation needs are limited.

System A
↔
System B
🧭

Integration service / middleware

Appropriate when several systems are involved, data needs transformation, retries and queues are required, or business rules sit between systems.

API layer for existing applications

Appropriate when an existing PHP application has no suitable API, internal business logic needs controlled exposure, or legacy systems need gradual integration.

Data Synchronization

Keeping two systems synchronized is a business problem, not just a technical one.

Before any code is written, these questions need clear answers.

Which system owns each piece of data?
What happens when both systems change the same record?
How are deletions handled?
Is synchronization real-time or scheduled?
How are failures retried?
What happens when IDs do not match?
Which system wins during a conflict?
How can staff see when a sync failed?

Defining ownership and conflict rules before implementation prevents many integration problems later.

How We Build Integrations

Five steps from mapping to monitoring.

Each stage gives us enough information to validate the approach before adding more complexity.

01

Understand

Map the systems, data, business rules, triggers, ownership and expected outcomes.

02

Verify interfaces

Review API documentation, authentication, rate limits, webhooks, database access and technical constraints.

03

Design

Define data mapping, error behavior, retry strategy, logging and the source of truth for each workflow.

04

Build & test

Implement the integration and test normal flows, failures, duplicates, missing data and external service issues.

05

Monitor & improve

Watch real usage, investigate failures and adjust the integration as external APIs or business workflows change.

Existing Applications

Your application does not need to be rebuilt just to connect it.

Existing PHP, Laravel and Symfony applications can often be extended with APIs, background jobs, webhooks and integration services without replacing the core system.

Add integrations to existing software

  • Expose controlled APIs
  • Consume external APIs
  • Add webhooks
  • Background synchronization and scheduled jobs
  • Queue processing

Integration Discovery

Start by defining the safest integration approach.

For teams that know two or more systems need to work together but need help choosing the simplest reliable way to connect them.

This is a focused technical assessment. Complex systems or undocumented APIs may require a larger discovery scope.

Engagement Options

Scoped to the APIs, data and rules involved.

Integration work is sized after we review the interfaces and the data, not before.

Focused work

Focused Integration Sprint

From $1,500
  • One defined integration
  • Webhook implementation
  • API connection
  • Focused data sync
  • Integration repair
  • Validation and logging

Final scope depends on API quality, authentication, data mapping and workflow complexity.

FAQ

Common questions about integrations.

Can you integrate with any API?

Not always. The external system must provide a usable interface, such as an API, webhook, database connection, export or import mechanism or another reliable access method. We review the available options before recommending an approach.

What if the API documentation is poor?

That is common. We can inspect the available documentation, test endpoints and identify limitations during discovery. Some integrations need extra investigation when the external platform is poorly documented.

Can you integrate an old PHP application?

Yes. Existing PHP, Laravel and Symfony applications can often be extended with API clients, webhooks, background jobs or a controlled API layer. See our application modernization work for how we approach older codebases.

What happens if an external API goes down?

A reliable integration expects temporary failures. Depending on the workflow, we use retries, queues, logging, alerts and fallback behavior to reduce the risk of data being silently lost.

Can you synchronize data both ways?

Yes, when the business rules support it. Two-way synchronization requires clear ownership and conflict rules so the systems do not keep overwriting each other.

Can integrations run in real time?

Yes, when APIs and webhooks support it. Some workflows are better handled asynchronously or on a schedule because of rate limits, data volume or business requirements.

Do you work with webhooks?

Yes. Webhooks are often useful for event-driven integrations such as payment events, status changes, notifications and synchronization.

Can AI be part of an integration?

Yes, when unstructured information needs classification, extraction or summarization. AI should complement deterministic API and business logic rather than replace it. See AI automation for how we use it in workflows.

Do you maintain integrations after launch?

Yes. External APIs change, credentials expire and business workflows evolve. AtomoWeb can keep monitoring and maintaining integrations after implementation.
