The question doesn't really make sense, because OData is a protocol for web services. Didn't you mean accessing data entities through OData web service vs. developing a custom service? If not, please explain what you actually need. Maybe you should focus on the description of the business problem, rather than jumping to technical terms.

Hi Martin,

Thanks. Yes, as a "Business Analyst", all the technical term is quite confusing. The behind story is in one of my discussion, there is a conversation during integration between D365 FO and external system, which described like "we are using OData, not web service", it is either I heard it wrongly or the person didn't explain correctly.

That's why I'm here asking for some fair easy to understand insight regarding this. So how exactly this OData and web service relate each other, or, is OData web service different than custom service ? how different and what is the Pro and Cons of it ? May I know a simple usage that make it different ?

Thanks again.

Hi Axel, In addition to above suggestions, You can try ChatGPT to understand concepts and technical terms.

"Web service" is a generic term for communication between applications through internet protocols, especially HTTP.

Open Data Protocol (OData) is a standard for one particular design of web services. Therefore an OData service is a specific type of web services.
