Hi,

If you point the data mapper 'Web Service' component at the swagger.json it should provide a complete JSON or (if the web service supports it) XML response.

E.g. https://bookstore.liquid-technologies.com/swagger/1.0.0/swagger.json

Will give the option to call "Find Books By status (GET)"...

With multiple option for the Response type...

Selecting "application/json" produces "Web Service 1" component, selecting "application/xml" produces Web Service 2" component...

Either can then be mapped onto an XML component.

As mentioned I tried that...
Didn't return much that was usable...

I found a python tool that generated JSON schema's from Open API, but while the resulting schemas look good when I open them directly.  Trying to use them in the data mapper gives me the same "everything in KV pairs" that I saw with the web service component.  I suspect it's a limitation due to the complexity of the schema, in particular the "Customer isOneOf (Business, Individual)"

OK, what do you see if when you expand the node "Value (Object)"?

Feels like it's being dynamically generated...and might not actually end...
This is 38 levels deep...

Hmm, yes that's not much use.

Would it be possible to provide the schema? If this is commercially sensitive, please create a support ticket.

This issue was fixed in v20.7.13:

Updated Data Mapper Web Services Components to expand nodes for AnyOf, OneOf, AllOf YAML schema and JSON Schema values.
