Do HTTP Request Node Calls Execute Sequentially Without Batching?
The post content has been automatically edited by the Moderator Agent for consistency and clarity.
Want to use over 200+ MCP servers inside your coding tools like Cursor?
I'm asking if the HTTP Request node processes requests sequentially when batch execution is not configured. Although Node.js supports parallel I/O via threads, the HTTP Request node documentation doesn't explicitly mention parallel execution, and testing this behavior is not straightforward.
I need to prepare an error report for a service provider and want to accurately describe whether the node makes requests sequentially or in parallel by default.
Cheers

Based on the documentation, when you don’t enable batching, the HTTP Request node processes the incoming items one by one (sequentially). Although Node.js itself can handle concurrent I/O, n8n’s workflow engine executes the HTTP Request node sequentially unless the batching options are explicitly configured.
In your error report you might state:
"The HTTP Request node in n8n, when not configured with batch execution, processes the requests sequentially. Even though Node.js supports concurrent I/O, default node execution does not run HTTP requests in parallel unless batching is enabled to deliberately perform parallel requests or introduce delays between requests."
This should help clarify the behavior for the service provider.
