Differences between WebAPI ver 8.2 vs ver 9.x oData calls

(0) ShareShare

HI 

This is regarding the weird differences seeing between v8.2 and v9.x Web API oData calls

The html web resource is currently working with v8.2 version and when changed to 9.x does not work. When troubleshoot, weird thing is observed.

var query = clientURL+"/api/data/v8.2/entity?$select=fld1;

When changed above URL to var query = clientURL+"/api/data/v9.1/entity?$select=fld1 it fails as the attribute fld1 does not exist at all.

The actual schema name is fld and it is OptionSet type.

When corrected the schema name with v9.1 it works great --> var query = clientURL+"/api/data/v9.1/entity?$select=fld.

Question is : When the attribute name itself wrong how the v8.2 query is working.

What is the difference between v.8.2 endpoint v/s v9.1 endpoints? From where it is referring.?

Any insights would be great and helpful.

Thanks in advance

    As per my understanding there is no such difference. Point to remember is that WebAPI calls are case sensitive. Additionally in your case you may be having an old field with name "fld1".

    WebAPI (8.2 or 9.0) will not be able to call any field which is not part of your CRM schema :) until you are pointing to correct CRM instance.
