Refactoring a Fragile iPaaS Architecture into Native Operations Hub Logic for a Telecom ERP
A fragile Make.com middleware integration with an eLation ERP was throwing widespread HTTP 400 errors and creating duplicate records for a telecom provider. We refactored the architecture. Data cleansing moved natively into HubSpot Operations Hub, and strict UI-level field validation now runs before deals can advance to provisioning.
Executive Summary
Context
A specialized telecom provider's critical ISP provisioning workflows kept breaking. A fragile, failure-prone middleware integration (Make.com) with their eLation ERP was the cause.
What We Built
We refactored error-prone middleware logic into native HubSpot Operations Hub data cleansing workflows. Mandatory UI-level validation backs them up.
Tech Stack
- eLation (ERP), Make.com (formerly), HubSpot Sales Enterprise, Operations Hub.
Not a fit if the system of record lacks a stable REST API. Same if real-time, high-volume transactional data needs sub-second latency processing.
The Challenge
Our Approach
The messy reality forced a choice. We decided to stop trying to solve eLation's data structural issues inside Make.com's interface. That approach was unsustainable. We refactored the entire flow. First, we implemented native data cleaning within Operations Hub and deleted the fragile Make.com deduplication scenario entirely. Then we tackled the HTTP 400s by moving validation upstream. Rather than build a complex post-submission check, we customized the left sidebar in HubSpot so those specific eLation-required fields became mandatory before a rep could move a deal to "Closed-Won." By the time the final workflow gathers the data and sends it to eLation, it's already clean.
Impact
HTTP 400 Errors Stopped at the Source
We moved eLation required-field validation to the UI layer. That stopped HTTP 400 "missing property" errors from ever hitting the API submission point. The data only leaves HubSpot once it is verified complete.
Elimination of Middleware Deduplication Cost
We deleted the four-step Make.com duplicate checking scenario. HubSpot Operations Hub's native deduplication now handles this automatically, matching on phone numbers and emails. That cut active scenario overhead.
Stabilized ISP Provisioning Workflow
We shifted critical logic natively into HubSpot. Closed-Won deals now transfer to the eLation order pipeline automatically and reliably, with no dependency on fragile multi-step middleware execution.
Native Data Formatting
Operations Hub automation now standardizes phone number formats (dashes vs. no-dashes) directly on the HubSpot contact record before external syncing. Middleware logic no longer has to manage that.
We customized the left sidebar of the HubSpot Deal object. Specific eLation required fields, found through forensic log analysis, became mandatory properties before a deal could advance past certain stages.
We activated HubSpot Operations Hub's automated data quality features. That replaced custom middleware logic. The old logic had manually searched for and merged contacts sharing the same primary phone number or email address.
Instead of relying on eLation's instant, error-prone webhooks to trigger data creation in HubSpot, we inverted the flow. That change mattered. HubSpot fires the refined, validated payload to the eLation API endpoints when deal stage automation runs.
We consolidated and deactivated complex scenarios like "Create eLation order from HubSpot" and "Send Accounts from HubSpot to eLation." Moving execution natively cut operational quotas.
Fragile third-party middleware connections to ERP systems frequently cause HTTP 400 errors and record duplication. Refactoring the integration to use native HubSpot Operations Hub shifts data cleansing directly into the CRM. By enforcing UI-level validation before deals advance, the architecture resolves API race conditions and stabilizes provisioning workflows.
FAQ
We deleted the four-step Make.com duplicate-checking scenario entirely. We activated Operations Hub's native data quality features instead, which deduplicate automatically on phone number and email. That removed the fragile middleware logic that had fired on the instant eLation webhook and created duplicate accounts.
