Odata Delta Data

Hi there, I am currently trying to get the delta data for some entities by adding changedDate to them and trying to use a filter in the Odata GET call, but the date functions do not seem to work. I am able to use a few other query options successfully, just can not seem to do any kind of date function or get the delta data for a specific entity. Could somebody please give me an example of what this URL should look like to get the delta data based on the changedDate attribute. Thank you in advance! (Edit: The URL I am currently trying to make use of is as follows: https://****-accp.mendixcloud.com/odata/****/****?$Filter=day(changedDate) eq **)

Are you using the odata module from Mendix?


Hello Bertram,

I found that there is no easy way to consume Mendix ODATA within Mendix ironically and the feature seems to be ,in my opinion, targeted more at allowing reporting tools to run on it. I’ve been using ODATA for a while now but found it to be lacking in a lot of ways.

While I don’t have a solution for your issue, I would suggest that you use published app services instead, they’re the easiest Mendix-to-Mendix Integration in my experience. You effectively export Microflows to be used from another Mendix app, it even comes with a mini-model when imported in the second app.

Edit: If any of the options in the comments work, could you let me know which one?

Hope this helps


The documentation for OData filtering says that you should use:



datetime’<epoch value here>’

So I think your query string is like this:

filter=day(changedDate) eq datetime'1548793560'


See the second table in the Filtering section: https://docs.mendix.com/refguide/odata-query-options#4-filtering
