APIs and Integrations

Connect systems while keeping control of your information.

Fidalgo builds APIs and integrations to move information between systems under clear rules. The work starts with a specific workflow: which data moves, who may access it and what should happen when a step fails.

Discuss an integration

Who it is for

For teams repeating data entry, moving data through spreadsheets or connecting ERP, CRM, portals and external services without replacing their entire operation.

Problems we address

The same information is entered in multiple systems and versions conflict.
Synchronization failures go unnoticed or require manual corrections.
A new workflow depends on data from systems that do not communicate adequately.

Possible deliverables

APIs and data contracts

Endpoints for defined workflows, with authentication, permissions, validation and documentation. Definition of formats, rules and compatibility between consumers.

System connections

Integrations using APIs, webhooks or batch processing, depending on the systems involved. Field mapping, a source of truth and update rules.

Failure handling

Operation records and reprocessing mechanisms where applicable. Duplicate prevention, request limits and criteria for detecting discrepancies.

How to start

Choose a workflow that currently requires manual work. Share the systems involved, approximate volume, required frequency and where documentation and test access are available.

From context to operations

Map workflow and data
Identify sources, destinations, owners, permissions and rules for resolving conflicting information.
Define the contract
Agree on fields, frequency, failure behavior and acceptance criteria; check each system’s limitations.
Implement and test
Build the connection and validate normal cases, duplicates, limits and unavailability of connected systems.
Release and document
Monitor the transition to operations and record access, monitoring, reprocessing and maintenance responsibilities.

Scope and limits

Feasibility depends on access, documentation and interfaces of the connected systems. Licenses, API consumption and third-party changes need separate consideration. External availability and real-time synchronization are not assumed; timing, maintenance and change handling are defined in the proposal.

Questions about working together

Does the system need an existing API?

A documented API helps, but it is not the only option. We assess officially available interfaces and formats. If there is no suitable path, that limitation must be resolved before committing to delivery.

How does the integration handle duplicate or conflicting data?

We define the source of truth and how to identify records and updates. Duplicate prevention, conflicts and reprocessing are part of the workflow contract.

What happens when a vendor changes its API?

The integration depends on the vendor’s contract and availability. Monitoring, version upgrades and maintenance after delivery need agreed responsibilities and terms.

Next step

Describe which systems need to communicate and which task this should solve. That workflow helps assess feasibility, dependencies and the first deliverable.
