Key learnings from our experience
After managing over 100 PSP integrations throughout my career, I compiled the most important lessons into this comprehensive guide published on the Payrails blog.
Core Topics Covered
Workflow Flexibility - Why adopting adaptive methodologies like Kanban helps handle the inevitable roadblocks that come with PSP integrations.
Team Structure - The benefits of pairing developers to balance knowledge sharing while maintaining team velocity during complex integrations.
PSP Timeline Management - Recognizing that PSPs operate independently and may require unexpected maintenance windows or experience delays outside your control.
Critical Integration Elements - Why chargebacks, webhooks, and automated post-authorization operations should be prioritized early in your planning, not treated as afterthoughts.
Business-Aligned Decisions - How to select PSPs based on comprehensive business needs, not just API appeal or developer experience.
User Experience Focus - Designing intuitive payment interfaces that minimize friction while maintaining security and compliance.
Communication Strategies - Using concrete data when addressing PSP issues rather than vague complaints to get faster resolution.
The key takeaway: PSP integration involves far more than connecting API endpoints. It requires strategic planning, organizational discipline, and understanding both technical and business perspectives to succeed.
