ACW Soft Solutions

API development and system integration

Connect the systems a business process relies on. ACW defines API behavior, data exchange rules, and failure handling, then implements and tests the agreed integration workflow.

Trace the information between systems

An integration scope needs to establish which system owns each record and when other systems should receive it.

  • Repeated transfer

    People copy, import, or export information to move a task forward.

  • Difficult changes

    A new service or partner requires changes across undocumented interfaces.

  • Conflicting records

    Systems hold different values, with no agreed owner or rule for reconciliation.

Specify the connection and its limits

  • API contracts

    Define operations, inputs, responses, authentication requirements, validation, and error behavior.

  • Data flow

    Map fields, record identifiers, transformations, update direction, and timing. Define what happens when information is missing or conflicts.

  • Third-party connections

    Work within the provider's available interfaces, permissions, rate limits, and test environments. Identify provider dependencies before estimating implementation.

  • Operational behavior

    Define retries, duplicate-event handling, logs, and exceptions requiring attention. Assign responsibility for monitoring and provider changes.

From interface review to a tested workflow

  1. 01.

    Review the systems

    Examine API documentation, access, record models, and the business process.

  2. 02.

    Define the exchange

    Specify contracts, mappings, permissions, and acceptance scenarios.

  3. 03.

    Build and test

    Implement the agreed connection and check expected, missing, repeated, and failed events.

  4. 04.

    Release and hand over

    Verify the connection in the intended environment and document how exceptions are surfaced and resolved.

What you receive

  • API or integration specifications for the agreed scope.

  • Implemented endpoints, connectors, or data exchange workflows.

  • Test findings covering required data and failure scenarios.

  • Operational documentation and ownership of follow-on maintenance.

Acceptance can check record completeness, update timing, duplicate handling, and manual work remaining. Synchronization behavior depends on provider constraints and the agreed design.

A workflow example, not a client case.

Illustrative engagement scenario

An approved booking needs a corresponding CRM record. The scope maps identifiers and required fields, defines the trigger, and specifies what happens if the CRM is unavailable. Tests include a repeated booking event so retrying the transfer does not silently create another record.

Questions before an integration

What if a system has no API?

Review the supported exchange methods and constraints. Another mechanism may be possible, but feasibility must be assessed before promising a connection.

Can all records update instantly?

Timing depends on provider interfaces, limits, workload, and the integration design. Agree the required behavior and how delays are handled.

Who handles changes to a provider's API?

Assign responsibility for monitoring changes, maintaining credentials, and updating the connection. Continued maintenance needs a defined scope.
