# Automatically answer GitHub issue queries via webhook using Pinecone and OpenAI
This workflow automates responses to technical questions about code and documentation, typically arriving as GitHub issues. Using vector search and a LangChain AI agent, it retrieves relevant context and generates accurate answers—reducing manual effort and accelerating developer support. Designed for engineering and DevRel teams managing open-source or internal API projects.
## Who it´s for
- Developers looking to automate replies to GitHub issues.
- Tech leads aiming to speed up issue resolution in open-source projects.
- DevRel teams offering automated documentation support.
- Engineers integrating vector search into technical support workflows.
## What the automation does
- Receives incoming queries via HTTP webhook.
- Performs semantic search in Pinecone’s vector database containing code and docs.
- Uses a LangChain agent with OpenAI models to generate contextual responses.
- Returns the generated answer through the same webhook.
- Enables testing logic on new features or bug reports.
## What´s included
- Ready-to-use n8n workflow.
- Trigger and handler logic for webhooks.
- Integrations with Pinecone, OpenAI, and HTTP API.
- Basic text instructions for launch and adaptation.
## Requirements for setup
- n8n account with workflow execution access.
- Pinecone account with pre-loaded code and documentation vectors.
- OpenAI API key with model access.
- Access to external webhook endpoint (e.g., from GitHub).
## Benefits and outcomes
- Reduced response time to technical inquiries.
- Lower manual workload for developers.
- Improved answer accuracy using up-to-date documentation.
- Scalability for handling high query volumes.
- Ability to test documentation quality via AI-simulated questions.
## Important: template only
Important: you are purchasing a ready-made automation workflow template only. Rollout into your infrastructure, connecting specific accounts and services, 1:1 setup help, custom adjustments for non-standard stacks and any consulting support are provided as a separate paid service at an individual rate. To discuss custom work or 1:1 help, contact via chat
