AUTOMATION / INTEGRATIONS
Connect the systems the work already depends on.
Aevrion builds integrations between business systems so information and actions move reliably between them—defined connections with explicit data mapping, deliberate access, designed failure behavior and a named owner.
Every unconnected pair of systems is currently integrated by a person: copying, re-entering, reconciling. Integration engineering replaces that human bridge with a connection the business can inspect and trust.
01 / THE CONNECTION QUESTIONS
Every integration answers six questions.
Before any connection is built, its behavior is defined. These six questions are the definition—and a connection that cannot answer them is not ready to carry the business.
- 01
WHAT MOVES
The exact information or action crossing the connection—which fields, which records, which operations—stated, not assumed.
- 02
WHEN IT MOVES
The events, schedules or triggers that cause movement: on creation, on change, on a rhythm, on demand.
- 03
DIRECTION + SYNC
One-way or two-way, which system is the source of truth, and how conflicts between them are resolved.
- 04
ACCESS + CREDENTIALS
What each system permits the connection to see and do—granted deliberately, scoped to the need and owned by someone.
- 05
FAILURE BEHAVIOR
What happens when the far side is down, rejects the data or answers slowly—designed, not discovered in production.
- 06
OWNERSHIP
Who is responsible for the connection's behavior, its credentials and its changes after launch.
The questions look simple. The engineering is in answering them for the systems you actually run—not for the ideal ones.
02 / THE INTEGRATION SURFACE
What a connection is actually made of.
The technical elements every integration is composed from. Which of them an engagement uses depends on what the connected systems expose and what the movement requires.
- 01
APIS
The primary connective tissue: the interfaces systems expose for reading and writing, whose quality and limits shape what is possible.
- 02
WEBHOOKS
Event notifications pushed between systems where appropriate—so movement happens when something occurs, not when something polls.
- 03
FIELD + DATA MAPPING
The explicit translation between how each system names, formats and structures the same information.
- 04
EVENT TRIGGERS
The defined occurrences that start movement, chosen deliberately from what each system can reliably signal.
- 05
SYNC BEHAVIOR
How state is kept coherent across systems over time—including what happens when the same record changes in two places.
- 06
PROVIDER DEPENDENCIES
The third-party platforms a connection relies on—acknowledged as dependencies, with their limits and terms treated as design inputs.
Aevrion stays platform-neutral: the connection follows the workflow and the systems involved, and no platform partnership is implied by any choice.
03 / RELIABILITY BY DESIGN
A connection is judged on its worst day.
Anyone can move data between two systems that are both working. Integration engineering is about what happens when one of them is not.
- 01
FAILURE IS A DESIGN INPUT
Every connection will eventually meet an outage, a rejection or a change on the far side. The design assumes it.
- 02
RETRIES WHERE APPROPRIATE
Transient failures are retried deliberately—with limits and awareness of duplicates—not hammered or ignored.
- 03
NO SILENT LOSS
Movement that could not complete is recorded and surfaced. Data that quietly never arrived is treated as a defect.
- 04
VALIDATION AT THE BOUNDARY
What crosses a connection is checked against expectations before the receiving system acts on it.
- 05
A NAMED OWNER
Someone is responsible for each connection—notified when it fails, consulted when it changes.
04 / ACCESS + CREDENTIALS
A connection extends the trust boundary.
Connecting two systems means one can now act inside the other. That power is granted deliberately, scoped narrowly and owned explicitly—conceptual principles that hold whatever the platforms involved.
- 01
LEAST REQUIRED ACCESS
A connection is granted the narrowest scope that serves its purpose—read what it must, write only where it should.
- 02
CREDENTIALS HANDLED DELIBERATELY
Authentication material lives in controlled configuration with defined ownership—never scattered or improvised.
- 03
BOUNDARIES STATED
What each side of a connection may see and do is an explicit decision, revisited when the integration changes.
- 04
REVOCABILITY
Access can be withdrawn cleanly when a connection is retired—because how an integration ends is part of its design.
The specifics stay out of public view by design. How any particular credential is stored or rotated is an implementation decision made per engagement—described to the client, not published. No certification or universal control set is implied.
05 / HONEST LIMITS
Not everything connects.
Saying so early is the service.
What an integration can do is decided by what the connected systems expose: the APIs they offer, the events they can signal, the data they will release and the rate at which they will do any of it. Some systems expose almost everything; some expose almost nothing; most sit in between. Discovery maps those limits before an approach is recommended—so the proposal describes a connection that can actually exist.
Provider dependency is part of the same honesty: a connection built on a third-party platform inherits that platform's limits, terms and pace of change. That inheritance is acknowledged and owned, not hidden.
An integration promised beyond what the systems expose is not ambitious. It is a failure with a delivery date.06 / DECISION SUPPORT
Questions to resolve before connecting systems.
01What does Aevrion mean by an integration?
A reliable, owned connection between business systems that moves defined information or actions between them: what moves, when it moves, in which direction, under which access, with designed failure behavior and a named owner. Not a box of connectors—an engineered part of the operation.
02Can our systems be integrated?
It depends on what each system exposes: available APIs, webhook support, data access and security constraints. Discovery maps those boundaries first, and the honest answer is sometimes a narrower connection than imagined—or that a responsible connection is not available. Aevrion does not claim every platform can integrate with every other platform.
03Do integrations require replacing our current tools?
No—integration exists precisely so the tools a business already uses can work together. Replacement enters the conversation only when a current tool cannot support the connection responsibly, as an explicit, separate decision.
04What happens when an integration fails?
The failure surfaces: transient errors are retried within designed limits, movement that could not complete is recorded, and the connection's owner is notified. Integrations that fail silently—dropping data with nobody aware—are treated as defects, not as an acceptable cost.
05How is access handled between connected systems?
On least-required-access principles: each connection is scoped to what its purpose needs, credentials are handled in controlled configuration with defined ownership, and access is revocable when the connection is retired. Implementation details vary by system; the discipline does not.
06Who maintains an integration after launch?
Defined before launch: a documented handoff to a named internal owner, or an agreed ongoing model in which Aevrion operates and monitors the connection. Third-party platforms also change over time—watching for that is part of ownership, wherever it lands.
07Is an integration the same as an automated workflow?
They are layered. An integration is the connection that lets information and actions move between systems; a workflow is the defined business sequence that uses those connections. Some engagements are integration-only—making two systems agree—while most workflow automation depends on integrations underneath.
08What affects integration scope and cost?
The number of systems, the quality and limits of their APIs, data condition and mapping complexity, sync requirements, security constraints, failure-handling depth and the level of ongoing ownership agreed.
07 / START WITH THE SYSTEMS
Name the systems. Define what moves. Retire the human bridge.
Describe the systems that should be talking and the information a person currently carries between them. Aevrion will map what the systems expose and recommend the connection that can responsibly exist.
