Invoke REST API / Field forms populate

Hello Experts,
We're currently on BPS version 2021.1.2.143 (getting ready for upgrade)
I try to invoke a REST API to update form fields, and I get a proper response from the service, however, it doesn't update the fields.
I'm using OData Query to filter and expand the data, and load the response definition from the service.
The action configuration and action log with response are on my pictures.

What can I be doing wrong? The response is complete, however it doesnt populate the fields.

Thank you in advance for your help.


Hi Agnieszka,

I haven't used a similar example but I would check the following:
- property value
It's of type collection and I would assume, that you won't be able to assign a value from a collection to a single field. You would need to select an item list as the destination field for the collection.
- collection/array with objects
I haven't had this case where the collection/array contains objects. I don't know whether this will work.

If you can't make it work with an item list, you try to store the Response:Body in a multi line field and use SQL to extract the information.

Best regards,


Hi Agnieszka, Hi Daniel

I'm assuming that Daniel is right - we can't map collection items into single fields - Webcon expects item list.

There shouldn't be a need to store the body inside of a multi-line field though - it should be accessible through business rule on mapping page as 'Input value' parameter.
I'm parsing XML from REST-like API which returns XML instead of JSON. In attachment example mapping, and business rule used to get the XML content.

With JSON though it might be more tricky as OPENJSON requires database Compatibility Level at 130, and by default Webcon database are at 120 according to this*
You should be able to check it with this SQL:
SELECT compatibility_level
FROM sys.databases WHERE name = 'BPS_Content';

However i'm thinking right now, that you might be able to create an empty database with high compatibility level, create a new connection, and use that connection to query with OPENJSON available.
