I have just been assigned to a very tiny project. Although I have a team lead and other senior developers that I could go to but at the same time I am trying to learn things on my own. Actually there is web api call I need to make. I have been given this Developer Toolkit from this 3rd party. It contains WSDL for the service and few .xsd files and another document that contains the method names. Now I have been told that this call should be a reusable component and we should be able to use it in other projects or even in the same project but other locations.
Everything else is in this project is mainly using D365 forms, a couple of flows and mainly the base entities except for a few custom entities. This web service call needs to be triggered from D365 portal button. This portal stores its data in D365 backend. My question is what would be the best way to make this web service call? My understanding is plugins will not be useful in this case but I am not very knowledgeable about this. So any guidance would be helpful.
