BCE/KBO API with ERP and CRM: integration guide 2026

In brief

Connecting the BCE/KBO API to your ERP or CRM automates the enrichment of customer and supplier records: official name, VAT number, legal form, registered office address and active/ceased status. A Node.js or Python middleware is enough to bridge your business tool (Odoo, Salesforce, HubSpot, SAP) and the data from the Crossroads Bank for Enterprises.

Why integrate the API with your ERP/CRM?

Integrating the BCE/KBO API with your business tools allows you to:

Automatically enrich customer/supplier records

Validate BCE/VAT numbers at input

Check the status of partner companies

Update addresses and legal information

Integration architecture

Use a middleware (Node.js, Python) between your ERP/CRM and the BCE API.

Node.js example

Create an endpoint that fetches company data and formats it for your ERP/CRM.

Best practices

Cache results to reduce API calls

Queue for bulk enrichments

Log all synchronizations

Conclusion

Integrating the BCE/KBO API with your ERP or CRM automates data enrichment and ensures the reliability of your business information.

Frequently asked questions

How do I automatically enrich customer records in my CRM with Belgian BCE data?

Create a middleware between your CRM and the BCE/KBO API: when a new customer is added, your system calls the /companies/{bceNumber} endpoint to retrieve the official name, address, legal form and active status. You then map those fields to the corresponding columns in your CRM via its REST API or webhooks.

Can I validate Belgian VAT numbers via the BCE/KBO API during data entry in my ERP?

Yes. The BCE/KBO API returns the VAT number associated with each company. You can create a trigger on the ERP side (for example an Odoo module or a Salesforce workflow) that calls the middleware when a BCE number is entered, verifies that the company is active and retrieves its official VAT number to pre-fill the corresponding field.

How do I regularly synchronize BCE data in my ERP to keep records up to date?

Set up a scheduled task (cron job) that calls the BCE API for each company in your portfolio and compares the returned data with what is stored in your ERP. In case of a discrepancy (address change, cessation of activity), update the record and send a notification to the relevant team.

What architecture do you recommend for connecting the BCE/KBO API to Salesforce or HubSpot?

Deploy a Node.js or Python middleware exposing a secured REST endpoint. In Salesforce, create a Flow with an HTTP callout to this middleware. In HubSpot, use a Workflow with the Webhook action. The advantage of the middleware is centralizing the caching, retry and mapping logic, without depending on each CRM's native capabilities.
