Hello! I can help automate the workflow between your PMS, messaging system, and payment processor so guest access and communication happen automatically without manual work. My approach would include building a secure automation service that listens for reservation events from your PMS API and triggers the required actions. Key automation steps: • Pull guest reservation data from the PMS API when a booking is created or updated. • Generate a unique 4-digit door code and store it with the reservation. • Send automated SMS messages to guests with their access instructions. • Process payments through your payment gateway API when required. • Automatically remove or deactivate old door codes when new ones are created or when a reservation ends. The system can be built using Node.js or Python with scheduled jobs or webhook listeners, ensuring everything runs reliably in the background. Deliverables will include: • Fully working automation scripts/services • API integrations with PMS, SMS service, and payment processor • Clean, documented code and setup instructions I can also help expand this later with additional automation or a voice/AI assistant for guest calls. Best regards, Jasmin

Hello, I can build a reliable automation workflow that integrates with your PMS API to manage guest access and messaging. The system will automatically pull guest data, generate a unique 4-digit door code, send the guest an automated SMS notification, process payments through your payment processor, and ensure old door codes are removed when new ones are issued. I have experience working with API integrations, automation scripts, and payment gateways, and I can design the system so it runs reliably as a background service with clear logging and error handling. The automation can be built using Python or Node.js, depending on your PMS API compatibility, and structured so future features (like a virtual assistant for call handling) can be added easily. Happy to review the API documentation and start building the automation.

Hello, I can automate your guest management tasks by integrating with your PMS via API. The workflow will generate 4-digit door codes, send automated SMS to guests, process payments securely, and remove old codes when new ones are created. I will ensure seamless API communication, robust error handling, and scalable automation that can later be extended to include a virtual assistant for call handling. The solution will be implemented using PHP or C# (based on your preference), with secure handling of payment transactions and data stored in MySQL if required. The automation will be reliable, maintainable, and fully aligned with your PMS documentation. Client Clarification Questions: Which payment processor do you currently use, and are there any specific API constraints? Should SMS notifications include custom templates per guest, or a single standard message? Thanks, Asif

Hi, As per my understanding: Automate PMS API guest tasks (4-digit door code gen, auto SMS, payment processing, old code cleanup); scalable for virtual assistant add-on. Implementation approach: - Node.js/Express microservice with PMS webhook integration. - Twilio SMS, Stripe payments, MongoDB/Redis for codes. - PM2 deploy VPS, error alerts via Slack/Email. I'll share my portfolio on your first message. Queries: PMS name/docs? SMS/payment providers? Code validity period? Thanks

Hello, I specialize in API-based automation and integrations that connect booking platforms, messaging services, and payment processors into one seamless workflow. I can build a custom integration (Python or Node.js) that listens to your PMS API, generates a unique 4-digit door code when a booking is confirmed, sends it to your smart lock, triggers the payment request, and automatically sends check-in details via SMS (e.g., Twilio). I’ll also add a scheduled cleanup to remove expired codes after checkout. Question: Which PMS system and SMS provider are you currently using? Best, Niral

Hi, your setup sounds clear, and it should be very possible to automate this workflow once the PMS API is connected. I can help build a small system that pulls guest details from your PMS, generates a 4-digit door code, sends the automated text message, processes the payment, and removes old codes when new ones are issued. The idea would be to keep everything running automatically in the background so guests receive their information without manual work from your side. I’m comfortable working with API integrations, automation scripts, and payment processing, and I can review the PMS documentation to connect everything properly. Happy to take a look at the API docs and discuss how the flow should work step by step.

Hello, This can be implemented cleanly and reliably with a small automation service that connects directly to your PMS API and orchestrates the full guest workflow. I have strong experience integrating third-party APIs, building event-driven automation systems, and handling payment processing securely. The system would listen for reservation events from your PMS, generate a secure 4-digit door code per stay, push that code to your lock system, and automatically remove any previous code when a new one is issued. It would also trigger an automated SMS to the guest with relevant instructions and process payments through your existing payment processor via API, with proper error handling and retry logic. I would build this as a lightweight backend service (PHP, C#, or Node depending on your preference) with logging, audit tracking, and secure credential storage. The architecture will allow future expansion, including adding a virtual assistant for call handling or AI-driven guest communication. Once I review your PMS API documentation, I can provide a precise timeline and estimate. Best Alex
