This guide explores the principles of synchronous API workflows, how Syncloop supports their implementation, and best practices for ensuring performance and reliability.

Understanding Synchronous API Workflows
What are Synchronous API Workflows?

Synchronous workflows are processes where each step waits for a response from the API before proceeding. This "request-response" mechanism ensures:

  • Immediate Feedback: Provides users or systems with instant results.
  • Logical Flow: Maintains a sequential process for tasks that depend on previous results.
  • Transaction Safety: Ensures data consistency in sensitive operations.
Key Use Cases
  • User Authentication: Validating credentials during login.
  • Payment Processing: Authorizing and confirming transactions.
  • Data Queries: Fetching records from databases or APIs.
Challenges in Synchronous API Workflows
  • Latency: Delays in response can disrupt user experience.
  • Scalability: Handling high concurrent requests without degrading performance.
  • Error Handling: Managing failures or timeouts effectively.
  • Dependency Management: Ensuring upstream or downstream services are responsive.
