API Development & Integration in Manchester
Connecting the tools you already use, and building custom APIs when you need your own systems to expose data securely to others.
Quick Answer
ZAVYANS provides API Development & Integration for businesses in Manchester, remotely from our offices in Islamabad and Arlington, Virginia, with calls in your business hours. The work typically covers webhook & automation setup, custom API development and legacy system integration, planned around local rules from the start, with reporting and invoicing in GBP.
Why Manchester businesses work with us
Calls in UK hours (GMT/BST) and written weekly reporting, so you always know what was done and what it produced
Work researched around Greater Manchester's real markets: Spinningfields, MediaCityUK, the Northern Quarter, e-commerce and the universities
One team running marketing, automation and software, instead of several suppliers who don't talk to each other
Reporting and invoicing in GBP, with London-level thinking at a price that suits Manchester budgets
Why your systems need to talk to each other
Most businesses run several separate tools, a CRM, a website, an accounting system, a booking platform, that do not talk to each other by default. Staff end up copying data between them by hand, which wastes time and causes errors. API development and integration connects these systems so data flows automatically.
We build integrations between the tools you already use, and custom APIs when you need your own systems to expose data to others.
What's included
Webhook and automation setup
Triggering actions automatically when something happens in another system.
Custom API development
Building APIs that let your own systems, or partners, access your data securely.
Legacy system integration
Connecting older systems that were not built to work with modern tools.
API security
Making sure data shared between systems is properly authenticated and protected.
Third-party integrations
Connecting your CRM, payment gateway, accounting or booking tools together.
Documentation and support
Clear documentation so your team, or partners, can actually use what is built.
Doing business in Manchester
Greater Manchester is home to around 2.9 million people across ten boroughs, and it is one of the UK's largest economies outside London. Spinningfields is the city's financial and legal district, MediaCityUK in Salford Quays hosts the BBC and ITV, the Northern Quarter and Ancoats are packed with digital agencies, startups and independent retailers, and the Oxford Road corridor links the universities, hospitals and Manchester Science Park. Manchester is also one of the UK's e-commerce capitals, home to fast-growing online retailers such as Boohoo and THG, and its student population is one of the largest in Europe. Businesses here tend to be practical, value-driven and open to testing new ideas, and we plan engagements with that in mind.
We work with Manchester businesses remotely from Islamabad, which is four to five hours ahead of the UK, so our working day overlaps your morning and early afternoon. Calls are scheduled in UK hours, reporting and invoicing are in GBP, and there is no Manchester office overhead built into our fees.
API Development & Integration rules in the UK
Websites and apps must handle personal data under UK GDPR and cookies under PECR, and public-sector sites must also meet accessibility regulations.
What's different about API Development & Integration in the UK
UK websites need to be fast, accessible and clear about cookies and personal data.
- WCAG 2.2 AA accessibility built in
- Payments through Stripe, PayPal, GoCardless or Worldpay, with VAT handled
- Cookie consent that meets UK GDPR and PECR
Integration work that pays for itself
The value of integration work is usually easiest to see in hours saved: an order that used to be re-typed into three systems now flows automatically. We scope integration projects around where your team is currently doing the most manual, repetitive work.
Building for Manchester users
Manchester's digital scene, from the Northern Quarter to MediaCityUK, means local customers are used to good digital products, and many businesses here sell nationally online. For API Development & Integration, we build for UK users from the start: UK spelling and formats, cookie consent that meets PECR, accessibility against WCAG 2.2, and fast performance on mobile, where most Manchester customers will first find you.
