Native connector
The supported objects, direction and update timing fit your workflow.
Check first: Confirm field coverage, plan requirements, exception visibility and who supports it.
Platform & workflow directory

your workflow needs.
Your team knows which tools it uses. The harder question is what should move between them. Explore specific platforms, data flows and access requirements before deciding what to build.

AppFolio
Assess maintenance, reporting and operational workflows against your account’s supported integration access.

Available integration options depend on the APIs, permissions and products enabled for your account.

Start with what already works
Native first. Middleware next. Custom when justified.
A reliable built-in connector may already solve the problem. We evaluate that first. The right choice is the smallest approach that handles your business rules and lets someone recover when an update fails.
02
Middleware such as Zapier or Make
A straightforward workflow can be expressed in supported steps at a manageable volume.
Check first: Test task costs, rate limits, recovery and audit history. Some middleware supports complex flows; evaluate the actual fit.
03
Custom API integration
You need account-specific mappings, controlled two-way sync, reconciliation, proprietary systems or review queues.
Check first: Budget for build and ongoing monitoring. Custom code still depends on vendor access and limits.
Where custom earns its cost
When moving a record is only part of the job
Business rules across teams
A deal may need an approved quote, a valid billing account and a scheduled job before an invoice should exist. Custom orchestration can coordinate those conditions, including the exceptions.
Controlled two-way synchronization
Two-way does not mean every field is editable everywhere. Define an owner for each field, retain stable record IDs and stop conflicting updates from bouncing between systems.
Volume, history and reconciliation
Large backfills, high-value transactions and recurring comparisons need capacity planning, queued processing, validation and a way to find records that never arrived.
Systems unique to your company
A legacy database, proprietary application or internal dashboard may need an integration service with its own rules, role-based review tools and audit trail. Supported access is still a prerequisite.

How connections are designed
Agree the data contract before the first sync
Identity, ownership and field mapping
Define the company boundary, source and destination IDs, required fields, transformations and conflict rules. An email address or business name alone is rarely a durable cross-system key.
Triggers, synchronization and validation
Choose supported webhooks, scheduled reads or a user-approved action. Validate against the destination’s rules, preserve version information and keep an audit record of each intended change.
Retry safely
For timeouts, rate limits and temporary server errors, use a bounded queue with backoff and jitter. Respect vendor retry guidance. Reuse a request identifier where supported and check uncertain writes before creating again.
Pause for a decision
Invalid records, missing permissions, expired authorization and ownership conflicts need a fix or review. Route exhausted retries to a failed-record queue with a reason, owner and controlled replay action.
Reconcile the outcome
Duplicate or delayed events must not double-post work. Compare intended records with destination state on a schedule; monitor queue age, last successful sync and unresolved differences. An HTTP 200 is only one check.
Only the access the workflow needs
Use the vendor’s supported authorization flow and least-privilege permissions. Keep credentials in encrypted server-side secret storage, rotate or reconnect them through a documented process, and separate test from production access.
Validate webhook authenticity using the vendor’s supported mechanism before accepting events. Minimize copied personal and financial data. Redact tokens and sensitive payloads from logs, restrict replay tools by role, and retain an audit trail of changes and operator actions.
A practical delivery approach
From systems discovery to monitored operation
A proposed integration project follows ALCA’s discovery, design, build and launch approach. The exact scope and ongoing support responsibilities are agreed before delivery.
01
Discover & verify
Walk through the current process. Confirm customer authorization, account products, API access and existing connectors using representative records. Deliver a feasibility decision before promising the connection.
02
Map & design
Agree record ownership, company boundaries, fields, triggers, conflict rules, authentication and success criteria. Identify what requires human approval and what should never synchronize.
03
Build & test
Build the narrowest useful flow, then test duplicates, unavailable APIs, revoked access, invalid data and replay. Use vendor sandboxes where available; otherwise agree an isolated, authorized test approach.
04
Launch & observe
Reconcile historical backfill separately, release in controlled stages and monitor actual outcomes. Hand over mappings, credentials ownership, operating instructions and a maintenance plan for vendor changes.
