How to use Splunk REST API to create/update a role with more than 1 index access?

[premrajvs]

I am trying to create roles via API and here is the curl request. Question I have is, I am not able to add more than 1 index to the srchIndexesAllowed field either when I create the role or when I update the role. I am not able to find any Splunk documentation around the request body.

Does anyone know how I can add/update multiple indexes for a role.

curl --location 'https://XXXXXXXXXXXXXXX/services/authorization/roles/fi_a00002-namespace_nonprod_power' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'Authorization: Basic XXXXXXXXXXXXXXXX' \
--data-urlencode 'imported_roles=user' \
--data-urlencode 'srchIndexesAllowed=index1,index2' \
--data-urlencode 'srchIndexesDefault=index1,index2'
