Define the source
List systems, records, immutable IDs and ownership rules.
Full Custom API
Your systems.
One governed connection.
Connect approved business software to JielianERP with explicit ownership, secure mappings, retries and reconciliation.
What is a custom ERP API integration?
A custom ERP API integration links an approved source system to JielianERP through a documented contract. The contract defines which system owns each record, how requests are authenticated, how fields map, what creates an ERP result, and how duplicate or failed events are recovered.
Build the contract before the automation.
A reliable connector is designed around source ownership, failure behavior and visible reconciliation, not only a successful API response.
Secure the boundary
Use scoped credentials, signatures, timestamps and replay protection.
Map the records
Resolve customers, items, currency, tax, bank and ledger relationships.
Process safely
Validate, lock and retry events without duplicating completed work.
Reconcile results
Show source, ERP result, status, exception and audit history together.
A custom API that behaves like a product.
Administrators need clear setup, predictable security and support tooling after the first successful call.
Tenant-scoped credentials
Encrypt credentials and bind every request to the company that owns the connection.
Explicit data contracts
Document fields, validation, ownership, mappings and expected ERP outcomes.
Idempotent events
Accept retries without creating duplicate customers, invoices, payments or journals.
Visible sync health
Track received, processing, completed, failed and attention-needed states.
Audit and recovery
Preserve payload identity, mapping decisions, failures and authorized reprocessing.
Questions answered
Clear answers before a sales call.
What is a custom ERP API integration?
A custom ERP API integration connects a business system to ERP records through a documented data contract. It defines source ownership, authentication, field mapping, validation, idempotency, retries and reconciliation before automation is enabled.
Can one company connection access another company?
No. Credentials, mappings, events and resulting records must stay scoped to the company workspace that owns the connection. Cross-company access is rejected by the tenant boundary.
Can the API send and receive data?
Yes, when the approved scope requires it. Inbound events can create or update controlled ERP records. Outbound jobs can return approved statuses or data while preserving source ownership and audit history.
How is a custom connector tested?
Testing covers authentication, invalid payloads, duplicate delivery, stale events, mapping conflicts, retries, partial failure, currency, balanced accounting and cross-tenant isolation.
