Custom API Integration Services
Connect the systems your team depends on.
CV Infotech builds custom API integrations when standard connectors cannot support your data, business rules or recovery needs. Define one workflow, the systems it connects and what should happen if a transfer fails.
Name the systems, the data that must move and the problem with the current connection.

Start with the workflow your systems need to share
We begin by mapping what has to happen in your business. A customer signs a contract and an account needs provisioning. A booking changes and another system needs the revised status. An internal tool needs information held behind a partner's API.
For each workflow, we identify where it starts, which system owns the record and what a successful result looks like. That gives the project a usable scope: the right information arriving in the right place, with a defined way to detect and resolve failures.
We can discuss a new connection, an unreliable existing integration or a change that an API provider is requiring. Share the systems involved and one representative example using fictional data.
Trace one record across your systems
A working connection includes the path for missing, repeated and rejected data.
- 01Trigger
Identify the event or schedule that starts the transfer and the system that owns the record.
- 02Map and validate
Match identifiers, required fields and allowed status changes before an update is attempted.
- 03Deliver
Send the authorised change, respect provider limits and record the actual response.
- 04Reconcile
Detect incomplete or duplicate work, show exceptions and define what can be retried safely.
Illustrative workflow for scoping. The final stages and responsibilities depend on your project.
The agreed scope
Custom API integration scope: data, events and recovery
Connections between existing applications
We establish the source and destination systems, available endpoints and access permissions. Your project may require an adapter in an existing application or a separate integration service. The choice depends on who will maintain it, where it will run and how tightly the systems need to depend on one another.
Data mapping and ownership rules
We agree how identifiers, fields, statuses and timestamps correspond, then document which system can update each value, how missing fields are handled and what happens when both systems change the same record. Historical data loading and ongoing updates should have separate acceptance criteria.
Webhooks and scheduled synchronisation
We choose the delivery method around the provider's capabilities and the business requirement. Some events can arrive through webhooks; other information needs scheduled retrieval. Define the acceptable delay, expected volume and behaviour when the provider throttles requests or is unavailable.
Failure handling and reconciliation
A connection needs a way to identify incomplete work. We scope appropriate retries, duplicate-event handling, error records and a reconciliation process. Your team should know which records need attention and what can be safely retried. Sensitive payloads should not be copied into logs unnecessarily.
Plan your project
Standard connector or custom integration?
A standard connector may be enough when it supports the required fields, permissions, volume and error handling. Custom development becomes more relevant when the workflow includes application-specific rules, unsupported endpoints, conflicting data ownership or recovery requirements that the existing connector cannot meet.
A list of app logos is not enough to estimate the work. A useful brief includes one complete workflow, example records, the expected volume and a named person who can answer business-rule questions.

How we work
From API documentation to a tested connection
Validate access and feasibility
Review API documentation, account permissions, sandbox availability, limits and any provider approval required. Record gaps before committing to a build scope.
Agree the integration contract
Document fields, ownership, event flow, timing, failure behaviour and acceptance tests. Identify sensitive data and decide what the integration actually needs to process.
Build and test the agreed workflow
Test the successful path alongside representative failures: repeated events, invalid records, timeouts and interrupted delivery. Use test accounts and suitable sample data wherever possible.
Plan cutover and ownership
Agree how existing records will be treated, who approves activation, how failures will be visible and who maintains the integration after handover.

Before you start
Custom API integration questions
Can you integrate with our particular software?
Share the product names, versions, API documentation and the workflow. Availability depends on accessible endpoints, permissions, vendor restrictions and the data you need. We establish those constraints before committing to a connection.
What if one system has no usable API?
Review supported alternatives such as scheduled exports or a vendor-provided connector. A browser-based workaround can introduce additional reliability and maintenance risks and needs separate evaluation. Some requirements may need a change to the source system.
Does synchronisation have to be real time?
Only where the business needs it and the systems support it. Specify an acceptable delay for each workflow. Provider limits and processing queues can affect delivery, so a real-time requirement needs measurable acceptance criteria.
What affects custom API integration cost?
The number of workflows matters more than the number of application names. Data transformations, historical records, failure recovery, test access and vendor restrictions all affect scope. Share your budget range and preferred launch date so we can discuss the appropriate first phase.
What happens when an API changes?
Agree who monitors provider notices, maintains credentials and tests version changes. Ongoing monitoring and maintenance should have explicit ownership and an agreed support scope. Third-party subscriptions and usage charges also need to be accounted for.
Start with a focused conversation
Describe the connection you need
Tell us which systems need to exchange data, what should trigger the exchange and what your team does manually today. Include known constraints, expected volume, budget range and target date.
Send documentation links or a fictional example. Please do not include API keys, passwords or real customer records in your first message.
