Keen on integrating your app with something?

We've integrated with some of the biggest names out there and on multiple occasions. It's rare that you'll come across an API or SDK we haven't worked with but we'd like to name a few for you.


We're already integrating our apps into ChatGPT to help automate things and provide more cutting edge technology to your users.


We've integrated using the .NET PayPal SDK to handle a community led marketplace selling used kids clothes and toys.


Stripe is our bread and butter integration with majority of our apps choosing this payment provider. We've done Stripe Checkout, Stripe Connect, you name it, we've done it with Stripe. We're even a Stripe partner!


From simple Shopify checkout integrations to full blown marketplaces allowing individual shops to sell their items, we've handled pretty much every use case with the Shopify SDK's.


Of course we've worked with one of the most popular CRM's in the world, Hubspot. From simple API integrations like creating new contacts to entire workflows integrated into apps, we've done it.


Pipedrive is a lesser known CRM that we use for our own sales pipeline. We've integrated with them using their .NET SDK's to handle our contact form hits on our website.


Algolia is the go-to tool for building highly scalable and lightning fast search functionality into your app. We've integrated with their REST API via their .NET SDK for a number of products.


NHS integrations are not easy, but we've worked with a number of trusts to successfully integrate their apps into a variety of their backend services, taking the necessary precautions with patient data.


Apple App Store In-App Billing to give some of the products we've built a seamless experience when it comes to purchasing in app items or subscriptions.


Atlassian Jira for handling tickets via a customer service desk. There are numerous API's that we've worked with in JIRA.
