SaaS start-ups often run into a situation where they have a great platform or app built out but forgot one important thing: integrating invoices and payments for their clients. This leads to quickly thrown together invoicing systems with poor quality outcomes, a lot of time spent back-and-forth between engineering and design teams, and ultimately a system that nobody wants to manage or develop with.
This API prevents developers from needing to develop a last minute micro-service, or jam invoice generation into their app. A single endpoint API accepts invoice data and builds out a PDF, which is then base64 encoded and returned to the developer. No linked files to download or anything like that, just request, receive the response, and decode with any base64 decoder.
I'd consider this API pretty light work as far as the actual activity of building an invoice goes, it's just one script that you can put together pretty easily if you have the time: but a typical SaaS company has 50 problems with that exact description and no time to do them. What's important about this project is that I was able to develop it on AWS with only a Lambda and an API Gateway, meaning that up until it hits 1,000,000 requests this API is completely free to run.
If you'd like someone with plenty of time, experience with AWS and developing back-end projects such as APIs and/or more advanced microservices, and the attention to detail in order to save costs: contact me, let's work something out!
