API integrations with third-party systems
API integrations link your website or portal to ERP, CRM, payment and newsletter systems and end manual data transfer.
Background
Orders go straight into the ERP, enquiries into the CRM and consents into the newsletter service. Before we start, we agree which system holds the master copy of each type of data. This prevents conflicting records.
Typical integrations
ERP: products, prices, stock levels and orders
CRM: leads and customer data in HubSpot or Salesforce
Payment: Stripe, PayPal or Mollie, with webhooks for status updates
Newsletter: Brevo, Mailchimp or CleverReach, with double opt-in
Single sign-on: Microsoft Entra ID or other identity providers
Technology
Most systems offer REST APIs or GraphQL. Older ERP systems often use SOAP or SFTP. We wrap all of these in a separate integration layer, so a third-party system can be replaced later without rebuilding the application.
Reliable in operation
Queues with automatic retries during outages
Idempotent processing, so no order arrives twice
Encrypted transfer and data processing agreements under the GDPR
Approach
We agree data flows and failure cases with your business teams and IT. Testing runs against each provider's sandbox. After launch, logging and alerts keep the integration monitored. Automated sandbox tests reveal changes to provider APIs early.
