    I’m running a Laravel 10 bulk-media sender that talks to WhatsApp Business Cloud through a webhook. Whenever the API answers with HTTP 429, the webhook does mark the message as failed, yet the queued retry flow (RetryFailedWhatsAppJob on Redis/cloud queue) rarely fires, and when it does, the image-ID matching logic sometimes mis-aligns. The result is missed retries or, worse, duplicate sends. Here’s what needs to happen: • Repair the webhook callback so the media object returned by WhatsApp is always matched to the correct outbound record. • Ensure the job is dispatched, picked up, and processed on the existing Redis-backed queue every time a 429 occurs, honouring the current attempt counter. • Implement a reliable back-off for those 429 responses so we r...

    Plaid + Chase Connectivity Issue via API Plaid + Chase OAuth Integration — "Invalid Credentials" After Successful OAuth Flow The Problem: We have a production Plaid integration (Node.js/Express) that connects bank accounts via Plaid Link. American Express and Capital One connect and sync perfectly. Chase fails every time with "Username or password incorrect" AFTER the OAuth flow completes successfully. The Flow: 1. User clicks Connect Bank → Plaid Link opens 2. User selects Chase → Plaid fires OPEN_OAUTH event 3. User redirects to Chase's website and logs in successfully 4. Chase redirects back to our app with oauth_state_id 5. Plaid Link re-opens with receivedRedirectUri 6. Plaid shows "Username or password incorrect" — connectio...

    Tenho hoje o ChatPion funcionando, porém preciso levá-lo a outro nível. Estou aberto a duas vias: aprimorar diretamente o ChatPion ou, caso seja tecnicamente mais simples, desenvolver um novo chatbot do zero para minhas páginas do Facebook. O que é indispensável • Envio de mensagens em massa sem limites artificiais, inclusive para várias páginas simultâneas. • Integração com outras plataformas (APIs externas, CRM, e-commerce ou o que for necessário). • Respostas automáticas mais inteligentes, capazes de entender variações de texto e entregar conteúdo personalizado. Além disso, quero um painel central onde eu consiga disparar campanhas, alterar configu...

    I have the complete source code for BDonor, a live web-app that is currently down because Clerk Auth hit its “100 user limit.” The break means I can’t even reach the admin panel, so I need a clean redeployment from the ground up. Right now the site is hosted on Vercel, but I’m open to keeping it there or shifting to something like AWS or Google Cloud if that would eliminate the Clerk ceiling and future-proof the project. I’m not certain which environment variables, build flags, or third-party hooks are mission-critical, so I’ll rely on your guidance to audit the repo, document what matters, and carry it over correctly. Key objectives • Spin up a fresh production instance under my own new accounts (hosting, auth, database, any other services). &b...

    Ich möchte automatisiert Trading-Signale aus TradingView in einen Discord-Channel schicken und gleichzeitig bei meinen Brokern konkrete Stop-Buy bzw. Stop-Sell-Orders inklusive vorab definiertem Stop-Loss platzieren lassen. Der Workflow muss mehrere Asset-Klassen abdecken, vor allem Forex und Rohstoffe, und mit folgenden Brokern funktionieren: FXCM, Black Bull Markets und FP Markets. Kernaufgaben • Signale aus TradingView abfangen (z. B. per Webhook) und ohne Verzögerung an Discord weiterleiten. • ggf. parallel dazu automatisch die passende Order beim jeweils hinterlegten Broker aufgeben – wahlweise Stop-Buy oder Stop-Sell – und sofort den Stop-Loss setzen. • Multi-Asset-Handling, damit unterschiedliche Symbolnamen/Contracts je Broker korrekt u...

    I have an existing Google Sheet that already captures the core data for my project. What I now need is a lightweight web app—built in HTML, CSS and JavaScript (or Google Apps Script HTML Service)—that connects to this sheet for real-time reading and writing. Here is how I picture the flow: • A clean, responsive front-end form where users can enter or edit records. • Direct integration with the current Google Sheet via Apps Script, the Sheets API, or whichever approach you find most efficient. • Basic navigation that lets me expand later into dashboards or reports. You will work alongside me, sharing code in a version-controlled space (GitHub or similar) so we can iterate quickly. I can supply the Sheet structure, sample data and access credentials as soon ...

    Fix Shopify PDP Apple Pay

    Terverifikasi

    I have Apple Pay enabled through Shopify Payments and the button shows up on every product page, but when a customer taps it the site jumps to the regular checkout instead of opening the Apple Pay sheet and completing the purchase in place. The payment never processes, and the same behaviour occurs on iPhone, iPad, Mac, Safari, and Chrome, so it isn’t a device-specific glitch. What I need is a clean repair or re-implementation of Apple Pay on the product detail page so the flow stays on the PDP, the Apple Pay modal opens, the charge is authorised, and the order is created in Shopify without any manual redirects. Please work directly in the theme (Liquid, JavaScript) or via Shopify’s Payments API—whatever is best practice—while keeping existing styling untouched. I...
