    I need my MAPSLY account fully configured and linked to HubSpot so that data flows cleanly both ways. The priorities are clear-cut: • Real-time data syncing – every change in HubSpot must appear instantly in MAPSLY and vice-versa. • Automated workflows – routing, task triggers, or other MAPSLY automations should fire automatically from HubSpot updates. • Custom reporting – I want location-based dashboards and exports I can share with the team. HubSpot information to sync is centred on Locations; addresses stored in HubSpot have to populate MAPSLY accurately so we can visualise and act on them inside the map interface. Custom fields will definitely be involved. You’ll map any bespoke fields I already use in HubSpot to their counterparts in MAPSL...

    Squarespace Meta Tracking Fix

    I already run Meta ads and have a working Squarespace site that pushes purchase data through Zapier into Facebook Conversions API, Brevo, and a Google Sheet. The basic flow works, but Meta still flags every event as “Missing user parameters” because four values never make it through: _fbc, _fbp, visitor IP address, and user agent. Here is what needs to happen next: 1. Add a lightweight JavaScript snippet to my Squarespace site (Code Injection is fine) that, on page-load, reads the existing Meta cookies (_fbc and _fbp) and also captures the visitor’s IP address and user-agent string. 2. Make those four items available to my Zap. I want them stored in a dedicated column for each field inside the same Google Sheet row that already holds the buyer’s email—ema...

    I’m wrapping up a secure communication app built on a Java Spring Boot back-end with a React front-end and a companion Android client. The remaining work is focused on three areas: • Razorpay gateway: hook up the new API keys, route payments through the existing purchase flow, and return clean success / failure callbacks to both the mobile and web layers. • Code clean-up: identify and squash the lingering bugs that block a production build. Most issues have already been isolated in the repo and just need solid fixes and regression checks. • Google Play closed testing: run the mandatory 14-day closed test track, concentrating on performance. You’ll configure the Play Console, gather metrics, and iterate on any findings so we end the cycle with a stable, compl...

    I’m building “PlanMyTrip”, a web-based travel budget planner that automatically creates a full itinerary around whatever a traveller can realistically spend. The site must have a dashboard-style layout where every core function is visible at a glance. Core functions to wire in: • Expense tracker that updates in real time. • Itinerary generator that adjusts activities, transport and lodging to stay within budget. • Destination recommendations that adapt as the remaining balance changes. Budget entry should feel effortless, so I want the system to connect directly to a user’s financial accounts through a secure API (Plaid, Stripe Financial Connections or similar). After authorisation, the app fetches available balance, categorises recent travel-...

    I run a small roofing company and I am moving our workflow into Quote IQ. I need someone who already knows the platform—and Stripe—to get everything connected and looking right the first time. Here is what I am trying to accomplish: • Import the data I already have (mainly the Stripe-related customer and payment details I exported) so it shows up correctly inside Quote IQ. • Complete the initial Stripe account setup, then configure it inside Quote IQ so new quotes can be paid online without errors. • Resize and upload our existing logo files so they display crisply on web and PDF quotes. Please let me know about your experience with Quote IQ, Stripe dashboards, and basic graphic resizing, as well as an estimated timeframe to get all three points finished....

    I run lead-generation campaigns on Meta and want its algorithm to shift from “more leads” to “better leads.” To do that, I need every form submission that comes in through my social-media ads to flow straight into a CRM and then back to Meta via the Conversions API, with the optimisation goal set to “Maximise number of qualified leads.” I haven’t settled on a platform yet—Salesforce, HubSpot, Zoho or another reliable CRM could work—so part of the brief is helping me choose or confirming that my current stack can do the job before you wire everything together. i need a free option. Once the CRM is agreed on, I’ll need the following: • Connect the chosen CRM to Meta using the Conversions API (server-side, not pixel only). &...

    The job centres on launching a fully functional Amazon affiliate marketing site on WordPress, styled with the ReHub theme that’s already licensed on my end. I have hosting and a fresh WordPress install ready; what’s missing is the full setup, design configuration, and the automated import of selected Amazon product listings. Scope of work • Install and configure ReHub so its product-comparison and deal modules work out of the box. • Connect the Amazon Associates API (or a proven import plug-in such as Content Egg, AAWP, or ASA2) with my tracking ID. • Transfer the product listings I’ll provide—titles, descriptions, prices, and primary images—so they populate WooCommerce-style catalogue pages, complete with affiliate buttons that open in n...

    I already run a fully configured Paid Memberships Pro installation on WordPress and now need the ivno () payment gateway woven into it seamlessly.

Deliverables: • Custom gateway module or plugin files added to Paid Memberships Pro • Configuration inside WordPress dashboard with ivno API keys and webhooks • End-to-end testing evidence for recurring, one-time, and refund flo...
