Virtual WhatsApp Multimedia Message API

@AwaisChaudhry

Hello, I understand you're looking for a simple and efficient API that allows a virtual WhatsApp number to send multimedia messages, specifically images and videos, on demand. My approach will focus on creating a user-friendly interface that ensures developers can easily integrate it into their systems. I will implement the functionality to send messages with optional captions and return a clear JSON response that confirms submission along with a unique message ID for tracking purposes. Additionally, I will include a lightweight authentication method to keep credentials secure, and provide thorough documentation to guide other developers through the setup process. A demo video or live sandbox will also be created to showcase the successful delivery of messages from the virtual number. What specific features do you want in the documentation to ensure it meets the needs of other developers? Thanks, Muhammad Awais

I've built similar WhatsApp Business API integrations, leveraging Twilio's platform for seamless multimedia message delivery and robust error handling. My experience includes designing scalable solutions handling high message volumes with efficient queuing and retry mechanisms. My approach involves using Twilio's Programmable WhatsApp API for message sending, implementing robust error handling and retry logic for reliable delivery. The API will accept multimedia data (images, videos) and metadata, process it securely, and send it via the WhatsApp Business API. A well-documented RESTful interface will ensure easy integration on your end. Ready to discuss this project? Could you share the desired multimedia formats and anticipated message volume to optimize the API's architecture for your specific needs?

Hello, I can build a clean, language-agnostic API for outbound WhatsApp messaging that supports image and video sends from a virtual number. The API will expose a single endpoint for dispatching messages, accept destination number, media (file or hosted URL), and optional caption, and respond with a JSON payload containing a unique message ID plus a status endpoint for delivery checks. Authentication will be lightweight (token/key in headers), making it safe for server-to-server integration without credential leaks. Questions: – Do you already have WhatsApp Business API / Cloud API access, or should I configure this using Twilio/Meta’s Cloud API as the underlying transport? – What media size limit should be enforced (WhatsApp supports ~16MB)? – Should delivery receipts be handled via a polling endpoint only, or do you also want optional webhook support for those who need it? I am a TOP Rated Freelancer, and you can check my reviews here as well: https://www.freelancer.com/u/kamran2012 Looking forward to potentially working together on this project. Thanks and Best regards, Kamran.

@Ekarthaan

Hi shanmd54, I recently completed a very similar project. I can show u sample. Questions 1) Will this use Meta’s WhatsApp Business Cloud API under your WABA and phone-number ID, or a third‑party aggregator? Do you want automatic handling of the 24‑hour session window with template (HSM) fallback for recipients outside session? 2) For media intake, should the API support both multipart uploads and hosted URLs? Any storage/retention constraints (e.g., transient memory only vs S3/GCS with presigned URLs)? Delivery receipts via webhook, pollable GET /messages/{id}, or both? Suggestions 1) Implement a provider‑agnostic adapter (Cloud API first) with normalized payloads, Idempotency-Key support, queue‑backed dispatch, exponential backoff with WhatsApp error heuristics, and a reconciler that maps provider events to sent/delivered/read/failed. Expose GET /messages/{id} and optional /webhooks/status. 2) Security and DX: API key + HMAC-SHA256 signature over body and timestamp; presigned upload endpoint to avoid exposing credentials; strict media validation/transcoding to WhatsApp constraints; token‑bucket rate limiting per API key; dedupe via content hash; comprehensive Postman collection and a mock/sandbox plus a real-number demo. You send me a message ok, lets discuss and btw my portfolio is uploaded here and on my website. Best Regards, Sid

@adisonw

Hello! I'm excited to see your project — it matches well with my experience building lightweight, production-ready APIs. I can deliver a REST API that accepts a destination number, media file (upload or hosted URL), and optional caption, then dispatches the message through your WhatsApp virtual number. The API will return JSON with a unique message ID and a delivery status endpoint. Authentication will be token-based, so it can be embedded cleanly in server-to-server workflows without exposing credentials. I’d build the service in Node.js/Express or Python/FastAPI, keeping it simple, well-documented, and easy to extend. I’ll provide Postman and cURL samples showing successful media sends, with error handling for invalid inputs or file size limits. A short README will cover setup, environment variables, authentication headers, rate limits, and error codes. For proof, I’ll include either a demo video or sandbox showing real delivery from the virtual number. The final handover will include source code, setup guide, and docs so other developers can plug it into their systems smoothly. Q1: Do you already have a WhatsApp Business API or virtual number provider, or should I suggest options? Q2: Should delivery status be exposed only as a polling endpoint, or also via optional webhook? Hope we can team up and make this project a success! Thank you for considering my proposal. Adison.

@huzaifa306

I can build a clean, language-agnostic HTTP API that sends outbound WhatsApp multimedia (images and video) on demand, accepts destination number + file or hosted URL + optional caption, returns a JSON submission response with a unique message ID and a delivery status endpoint, and secures requests with a simple token header. I’ll implement robust media validation, enforce configurable size and rate limits, and include concise error codes so other developers can integrate it reliably into their stacks. You will receive production-ready source code with setup instructions, a Postman/cURL collection that demonstrates text plus media sends, a README covering env vars media limits rate limits and error codes, and a short demo showing a real delivery from the virtual number. I’ll implement the integration using Twilio WhatsApp by default for fastest delivery and developer friendliness but can switch to the WhatsApp Business API or another provider if you prefer, and I’ll include a sample sandbox so you can test immediately.
