Can Celery simply be connected to another system via API?
Not always.
Having an API on both sides is like having two people who can speak, but in different languages. They’re both ready to communicate, but without a translator, the conversation won’t go very far.
That “translator” is what we call Middleware. Middleware sits between the two APIs and makes sure the information being passed back and forth is transformed into a format that both sides can understand.
Think of it like a travel adapter: Celery might be the laptop with a European plug, and the third-party application might be the power socket in the US. Both are fully functional, but unless you have the adapter (middleware), the plug simply won’t fit the socket. Once you add the adapter, everything works smoothly.
So, while APIs are essential for integration, in fact only middleware ensures that they actually work together.
Middleware usually still needs to be developed, unless it's an existing API integration.
The cost of middleware depends on the complexity of the integration. In other words, how many different functions do you want to connect between the systems, and does the data flow only go one way or both ways?
Contact us if you'd like a quote for middleware development. But before you get in touch, first determine and write down exactly what you need from such integration. That will answer our initial question, after which we can explore the possibilities.
