whatsapp API

Comprehensive WhatsApp API Integration Project with Advanced Features Project Description: We are inviting proposals from skilled developers or teams for an in-depth integration of the WhatsApp Business API into our system. This project demands proficiency in Python, with specific requirements for FastAPI and SQLAlchemy frameworks, and a focus on sophisticated data handling and privacy adherence. Detailed Project Deliverables: Extensive API Integration: Implement the WhatsApp Business API to manage diverse message types (text, images, audio, video, location, contacts) and identify message nature (Utility, Authentication, Marketing, Service). Message Categorization and Identifier Storage: Efficiently categorize messages and store identifiers for media content received from WhatsApp servers. SDK Development: Construct an SDK for simplified interaction with the WhatsApp API. Robust Database Design: Develop a comprehensive database in SQLAlchemy for managing user data and message logs, ensuring phone numbers are stored in E.164 format. Interactive and Media Message Capabilities: Enable sending of various message types, including interactive and media messages. Error Handling and Logging: Implement advanced error handling with detailed logging using the logger library, ensuring all actions are logged at different levels for effective debugging. Webhook Integration: Develop a reliable webhook for real-time data processing in coordination with the WhatsApp API. Unix Timestamp Usage: Employ Unix timestamps for all relevant data (messages for example), ensuring time-consistent data management. Unit Testing for Database: Incorporate comprehensive unit testing before data insertion into the database to ensure data integrity and system reliability. Additional Requirements: Full Ownership and Intellectual Property Rights: All developed software and integrations will be exclusively owned by us. Strict Privacy and Security Compliance: Adherence to GDPR, CCPA, and other data protection regulations is mandatory. Independence from Third-Party Services: The solution must be self-contained, with third-party services used only under our full access and control. Python, FastAPI, and SQLAlchemy Specificity: The development must be strictly confined to Python, FastAPI, and SQLAlchemy. The calls have to be Asyncronouse. Provision of Existing Code: We will provide existing code samples to guide the development process. And flow example. Proposal Submission Specifications: Outline a detailed methodological approach, including technology breakdown. Present previous experience with similar projects, focusing on the WhatsApp Business API. Include a comprehensive budget and timeline proposal. Plan for code quality assurance, maintenance, and bug-free delivery. Evaluation and Selection Criteria: Proposals will be evaluated based on technical depth, innovative approach, and alignment with our detailed requirements. Shortlisted candidates will undergo interviews and may be required to present their solutions. Final selection will be based on proposal quality, expertise demonstration, and project suitability. Expectations and Assurances: Deliver code that is thoroughly reviewed, free of bugs, and maintainable. Include a strategy for ongoing maintenance and future updates. Project Opportunity: This project offers a challenging yet rewarding opportunity for developers skilled in high-tech integration, with a keen emphasis on innovation, quality, and adherence to stringent data standards. We are excited to collaborate with a team that meets these criteria and look forward to reviewing detailed proposals for this dynamic project.
