More information about "/_vti_bin/client.svc/ProcessQuery" endpoint

[Aaditya-Rane]

I was going through the code which is use to set Tenant Properties.

storageentity-set.ts

There I came across a POST request to endpoint "${spoAdminUrl}/_vti_bin/client.svc/ProcessQuery"

But I am unable to understand the request body, which is send along with it. I also had search for the documentation about how that request body is constructed. But not able to find anything significant.

Can anyone provide additional reference about how that request query is getting formed ?

@Aaditya-Rane the ProcessQuery is undocumented; we tend to try and refactor the required properties by executing the request using CSOM and using Fiddler to capture the request that is send. Details on how SPO handles that are found here: https://docs.microsoft.com/en-us/openspecs/sharepoint_protocols/ms-csom/18c961c7-8384-4493-8227-54a3fffdc7cc but there is no documentation on what XML you can send to it other then using Fiddler (or other tooling to capture) to validate what is send.
