Integration is necessary and interesting to you.
Since I did not see specific information about what you need and where to take it from and what to do with it - in fact, I sent you to integrators who can provide you with their services - they will discuss with you what you need, agree on integration details, etc.
If we implement integration according to a specific technical task from our side, I think it will also be set up quickly and easily with us. But I do not see a technical task here, and I cannot develop it for you - there are integrators for this.
Integrators are not employees of our company. These are third-party partners that specialize in these types of requests.
