Construction · Procore custom integration
Your project team works in Procore. Accounting, leadership and subcontractor coordination may happen elsewhere. ALCA can design the connection around the specific records those teams need, with clear ownership and a way to recover when an update fails.
See the example workflowWe confirm your Procore tools, project permissions and app approval route first. Developer sandbox access does not by itself authorize an integration in your production company.
What could connect
Bring authorized project, RFI and submittal records into an internal reporting store. Show the last successful refresh and unresolved source errors alongside the figures, so a delayed feed is visible instead of looking like a healthy project.
Map job identifiers and permitted financial records to your ERP or accounting workflow. Start with the exact connector and financial-tool scope; agree cost classification and accounting acceptance before enabling transaction writes.
Use supported records to drive an internal outstanding-items queue or escalation workflow. Keep formal responses and approvals in Procore unless a specific write-back action, permission and conflict policy has been approved.
Use Procore file and folder references to connect document intake, review and an internal project portal. Check retrieval rights and revision handling before copying files into automated processing or exposing them to another audience.
Choose the right approach
Review Procore’s Marketplace and the supported ERP connector for your accounting product first. Existing connectors have their own supported objects, directions, setup requirements and approval controls; retain one that fits.
A supported middleware connector can be suitable for a notification or a small, straightforward record handoff. Test project coverage, event support and recovery with your actual Procore account before relying on it.
Custom engineering becomes useful for an internal ERP, cross-project reporting, proprietary job rules or review queues that existing options cannot represent. It still requires usable Procore endpoints and destination-system access.

Feasibility first
Procore documents a Private Developer route for an integration contracted for a single customer account. Organization verification and per-app production credential approval are separate steps. A reusable commercial product follows a different Marketplace path; ALCA does not claim either approval in advance.
Procore supports user-delegated OAuth and client credentials through Developer Managed Service Accounts for appropriate data connectors. Company administrators install the app and control its projects; access also depends on the declared company and project tool permissions.
Verify webhook coverage for each selected object. Queue events, retrieve the required records and run a reconciliation pass for gaps. Read current rate-limit headers and throttle dynamically; a fixed request allowance is not a safe project assumption.
Use the Developer Sandbox for initial testing. Customer sandboxes, enabled financial tools, region, production permissions and the final endpoint versions need separate confirmation. A working sandbox read does not prove access to every production record.
Technical scope checked against the official vendor references below. Production access is confirmed with your account administrator before implementation.
Follow the data
A supported Procore event or scheduled read identifies a change inside the authorized company and project scope.
The integration service records the source identity and processing state before attempting downstream delivery.
Check project mapping, required data, revision and destination rules. Missing mappings enter a review queue.
A reporting update may proceed automatically. An accounting handoff can wait for the agreed approval.
Deliver the permitted change to the ERP, dashboard store or portal and save its destination identifier.
Compare outcomes with source records. Retry temporary errors safely and surface unresolved differences to an owner.
Records & rules
This is an object-level design example, not an endpoint payload. Exact Procore fields, event support and any financial mappings are validated against the selected API version and your tools. Internal field names below are illustrative.
| Source object / field | Destination object / field | Direction | Trigger | Ownership, validation & conflict rule |
|---|---|---|---|---|
| Project · source identifier | Internal job · procore_project_id (example) | Procore → internal | Initial load + permitted change detection | Use company + project identity. Reject an unmapped project; never join unrelated jobs by name alone. |
| RFI · identifier and status | Operations queue · source_rfi_id, status (examples) | Procore → queue | Supported event or scheduled read | Procore owns the formal RFI. Re-read changed records; place missing project permissions in review. |
| Submittal · identifier and review state | Dashboard · source_submittal_id (example) | Procore → reporting | Supported change detection + reconciliation | Keep the source reference and refresh time. Handle removed access separately from a resolved submittal. |
| Document · file/folder reference | Project portal · document reference (example) | Procore → portal | Authorized file update or scheduled comparison | Check file access and revision before retrieval. Do not treat a stale file reference as the current approved document. |

Procore can own project-document state while the internal system owns staffing, routing or reporting fields. A reporting replica should not overwrite an RFI because its copy was edited later. Write-back is a separate, explicitly mapped capability.
A project ID is not an accounting job mapping. Agree the ERP’s job, vendor, cost code and transaction references with the people responsible for accounting. Reconcile accepted amounts and statuses, and hold ambiguous records for review.
When something breaks
An administrator may remove project access. Pause the affected stream and record the permission failure; do not assume every missing source record was deleted or erase the corresponding internal job.
A queue may still hold an earlier file revision when a new one arrives. Recheck the source reference, mark superseded work and retain the revision that produced each downstream result.
A bulk import or many project updates can exceed current capacity. Process at a controlled rate, expose backlog age and keep reporting freshness visible while the queue catches up.
Missing cost codes, vendor mappings or approval state need a business decision. Save the rejection and source identifier, then replay only after correction without duplicating already accepted transactions.
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.
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.
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.
Security by design
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.
From discovery to 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
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
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 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
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.
Buyer questions
We can assess a custom connection when Procore and your ERP expose the required authorized interfaces. Discovery checks the exact financial objects, directions and approval rules, then compares an existing ERP connector with a custom approach.
A single-account private integration has a documented route distinct from Marketplace distribution. Procore still requires organization verification and production approval per app. A product intended for distribution or reuse across customers needs the appropriate partner route.
Procore lists ERP connectors, including QuickBooks options. Online and Desktop have different requirements. We check the supported connector and data flow first; a custom extension is scoped only for the specific gap and available access.
Supported webhooks can reduce delay, but delivery, API capacity and downstream processing still affect freshness. We agree a useful update target, show the last successful refresh and reconcile missed changes instead of promising instant delivery for every object.
