I will ai automation for your base44 or replit app chat, webhooks, memory base 44 fix
Handrew
About this gig
I will integrate GPT-powered AI into your Base44 or Replit web app to add conversational chat, webhook-driven automations, and persistent memory so your app becomes context-aware and automates routine tasks.
What youll get:
- Secure GPT integration (server-side proxy, environment variables, no exposed keys)
- Chat UI + backend (optional streaming responses)
- Webhook automation (triggers, secure callbacks, retries)
- Persistent memory options (per-session DB, or vector store for semantic retrieval)
- Prompt engineering & cost controls (token caps, summarization, caching)
- Deployment-ready deliverables (documentation, tests, and security checklist)
How I work:
- Clear milestones with demos at each stage
- Keys kept in environment variables (OPENAI_API_KEY) and never committed to source control
- Rate limiting and token caps to control costs
- Optional extras: vector DB setup (Pinecone/Weaviate), OAuth/API integrations, monitoring
Deliverables (example for Standard package):
- Backend /api/gpt proxy endpoint that calls OpenAI securely
- Chat UI integrated into one page (mobile-friendly)
- One webhook workflow that triggers the GPT flow and returns results

FAQ
Do you need my OpenAI API key?
I can use your key or help you create one. For security I store keys only in environment variables (e.g., OPENAI_API_KEY) on your Replit/Base44 workspace keys are never committed or exposed client-side.
What exactly is included in the Standard package?
A: Standard includes a chat UI, a secure backend proxy endpoint, one webhook automation workflow, per-user session memory (temporary DB), token caps, basic rate limiting, and documentation plus 2 revisions.
Can you keep conversation history so the bot remembers users?
A: Yes — I offer per-session storage (DB) for short-term memory and an optional vector store (Pinecone/Weaviate) for long-term semantic memory and retrieval. Choose the memory option when ordering.
How do you secure webhooks and prevent abuse?
A: I implement HMAC or secret-token verification on webhook callbacks, validate and sanitize incoming payloads, add rate limiting, and log suspicious activity. I can also configure retries and exponential backoff for webhook delivery.
How do you control OpenAI costs and token usage?
A: I add token caps per request, use summarization to compress long histories, cache repeated responses where safe, and recommend model choices (e.g., smaller models for low-cost needs). I’ll add usage logging so you can monitor spend.
