Custom Salesforce integration development. Connect Salesforce to your business systems, messaging platforms, and websites. REST API, bulk data sync, workflow automation. Freelance developer in Barcelona.
Custom Salesforce integrations that go beyond AppExchange. I build API-first connections between Salesforce and your business systems with bi-directional sync, custom objects, and workflow automation. From EUR 2,000.
Salesforce is powerful but often operates as an island. Your sales team enters data in Salesforce, but customer conversations happen on WhatsApp. Orders come through your website, but the CRM does not know about them until someone manually updates the deal. Marketing sends emails from a different platform with no feedback loop to Salesforce.
Custom integration solves this by connecting Salesforce to every system your business uses -- in real time, with no manual data entry.
Salesforce REST & Bulk APIs: I use the Salesforce REST API for real-time operations and the Bulk API 2.0 for large data volumes (10,000+ records). OAuth 2.0 with JWT Bearer flow for server-to-server authentication.
Common integrations: Website lead forms to Salesforce Leads/Contacts, WhatsApp/Telegram to Salesforce Activities, e-commerce orders to Salesforce Opportunities, accounting system to Salesforce billing, custom objects sync with external databases.
Basic (EUR 2,000-3,500): Single system connection, one-direction sync, up to 3 custom objects. 2-3 weeks.
Standard (EUR 4,000-7,000): Bi-directional sync, multiple systems, workflow automation, custom Salesforce objects and fields. 3-5 weeks.
Enterprise (EUR 8,000+): Complex multi-org integration, data migration, custom dashboards, AppExchange-quality integration. 6-10 weeks.
I focus on custom integrations for specific businesses rather than AppExchange products. If you need a private integration that connects Salesforce to your specific systems, that is my specialty. For AppExchange-listed products, I recommend working with a certified Salesforce partner.
Yes. I connect WhatsApp Business API to Salesforce so that customer conversations appear as Activities on Contact/Lead records. Chatbot-qualified leads from WhatsApp automatically create Salesforce Leads with full conversation history. See my WhatsApp automation services for more.
