I’m looking for a small utility that focuses on one job only—submitting WhatsApp message templates for approval. All I need is a simple UI where I can choose a .txt file from my desktop, hit “Submit,” and have the utility forward that file to the WhatsApp template-approval endpoint under my Business account. Manual upload is the only workflow I require; no API batching or automated cron jobs at this stage. For now, the tool must accept plain-text (.txt) files exclusively. If you can leave the door open in the codebase for future PDF or DOCX handling, that’s a bonus, but it isn’t part of this initial brief. Deliverables • Stand-alone desktop (or lightweight web) app that lets me browse, select, and submit a .txt template file to WhatsApp for approval. • Clear README explaining setup, WhatsApp credentials needed, and a quick walkthrough of the submission flow. • Source code so I can maintain or extend it later. Acceptance criteria – I can upload a .txt file and receive a visible confirmation that the request was successfully sent. – All errors from WhatsApp’s side surface clearly in the UI or logs. – Code is clean and commented well enough for another developer to pick up. I need the approval of meta as a utility. That’s the most important thing
