Connect Your Applications and Reduce Manual Work Between Systems
Your website, customer application and business tools should exchange the information your team needs.
When systems do not connect properly, staff may have to copy records, check several dashboards or resolve conflicting information manually.
DOT IT Services develops APIs and integrates existing services for websites, mobile applications and business software.
We start by defining what needs to move between systems, which system controls the information and what should happen when a request fails.
What Do You Need Your Systems to Do?
You may need an API for a new application or a connection between tools your business already uses.
Common requirements include:
Custom API Development
An API allows applications to request information or perform agreed actions.
For a custom product, that might mean retrieving account details, submitting a booking, updating an order or accessing a report.
We can scope API development for:
Web Applications
Provide the backend functionality used by dashboards, account areas and customer-facing interfaces.
Define request formats, permissions and expected responses with the frontend team.
For interface development, explore our React developers and Next.js developers.
Mobile Applications
Connect an Android or iOS application to account information, transactions and other services.
The API should account for interrupted connections, session expiry and repeated requests where relevant.
We can discuss this alongside Flutter development or React Native development.
Internal and Partner Systems
Make selected information or actions available to authorised staff, suppliers or business partners.
Agree on access boundaries, documentation and how changes to the API will be communicated.
Third-Party API Integration
An existing platform may already provide the functionality you need.
The work is then to connect it correctly to your application and account for its capabilities, restrictions and operating costs.
CRM and Lead Management
Send enquiries to the appropriate records, assign information to agreed fields and route requests according to your workflow.
Define how duplicates, missing information and failed submissions are handled.
Payment and Subscription Services
Connect payment-related workflows such as checkout, billing status and subscription changes.
Testing needs to cover relevant outcomes, including failed payments, cancellations and repeated notifications.
Booking and Calendar Systems
Connect availability, appointments and booking updates.
Agree how the integration handles time zones, rescheduling and cancellations.
Inventory and Order Systems
Exchange product, stock, order or fulfilment information.
Identify which system controls each record and how differences will be reconciled.
Messaging and Notifications
Connect email, SMS or other approved messaging services to defined events.
Delivery status, provider limits and failed requests need consideration.
AI Services
Connect an application to an AI API or related processing workflow.
Data handling, output checks, usage limits and operating costs should be part of planning.
Explore our AI development support for broader application requirements.
Plan the Connection Before Writing Code
A successful integration needs agreement on how the workflow should behave.
What Triggers the Action?
Identify whether the exchange starts with a user action, scheduled process or notification from another service.
Which Information Is Required?
Define the fields, formats and validation rules. A record that is acceptable in one system may need additional information before another system can use it.
Which System Owns the Record?
Establish where each piece of information is maintained. If both systems can change the same field, agree how conflicting updates will be handled.
What Happens When Something Fails?
Plan for unavailable services, expired credentials, rejected requests and incomplete information. Decide whether the process should retry, alert a person or wait for correction.
How Will the Result Be Checked?
Agree on what successful processing looks like and how your team can identify unresolved records.
Example: Website Enquiry to CRM
A website-to-CRM connection may appear to be a simple form submission.
The complete workflow could require:
This is an illustrative workflow. The actual implementation depends on your forms, CRM capabilities and business process.
For a broader interface around customer records, discuss customer portal development.
Connect a customer portal to your systemsMake Integrations Easier to Operate
Your team needs to understand whether the connection is working and what to do when it is not.
Depending on scope, implementation can include:
Authentication and Permissions
Use the access method required by the connected services and limit permissions appropriately.
Credentials should be handled through an agreed process.
Validation and Mapping
Check incoming information and transform it into the format the destination expects.
Document important rules so future changes can be assessed.
Webhooks and Event Handling
Process notifications from external systems.
Where events can arrive more than once or out of order, define how the application avoids unintended repeated actions.
Retries and Recovery
Plan suitable handling for temporary failures.
Some failures should be retried; others need a corrected request or human intervention.
Logs and Status Information
Record useful operational information without unnecessarily exposing sensitive data.
Agree what your team needs to see when investigating a problem.
Documentation
Document the connection, configuration, dependencies and relevant limitations.
A future developer should be able to understand how the integration is intended to work.
Improve an Existing API or Integration
You may already have a connection that fails intermittently, creates duplicate records or no longer supports the business workflow.
We can discuss investigation of:
Share reproduction examples, available logs and the systems involved.
Where the wider application is unfamiliar, an assessment may be appropriate before repair work is estimated.
Application technical assessmentDevelopment Around Your Existing Stack
The technical approach should fit your application and the connected services.
Relevant options may include:
Testing Before Release
The test scope should reflect the consequences of a failed or incorrect exchange.
Relevant checks may include:
Where possible, testing uses an appropriate non-production environment before authorised production checks.
Some providers offer limited test environments. Any resulting limitations should be documented.
API Development Costs and Timeline
The estimate depends on the functionality, documentation and systems involved.
Important factors include:
DOT IT’s development rate starts from $25/hour. The applicable rate, effort estimate or fixed project fee is confirmed after reviewing the scope.
Provider subscriptions, usage charges and account approvals are separate unless expressly included.
What Happens After Launch?
An integration can need attention when a provider changes its API, credentials expire or your business process evolves.
Agree who owns the connected accounts and who will respond to operational issues.
Ongoing monitoring, updates and troubleshooting can be discussed through our application maintenance and support service.
