Set Related record as parameter in workflow payload

[dodom2]

Hi All,
I have a use case where I want to send POST data to an external service when a record is deleted.
I use the @delete signal for this pupose.
My payload looks like this: {
"instanceId": "{$id}",
"instanceName": "ProductOptionSets",
"action": "delete",
"opencartRecordId": "{$opencartRecordID}",
"storeId": "{$companyBrandsIds}"
}
Problem is the "companyBrandsIds" never get replaced by the ID of the selected related record. What is correct formula to use and get the "companyBrandsIds" field sent?
More details in the image
Thanks.

Hi,

Unfortunately arrays are not supported there. I don't know now of any possible workaround.
