Depending on a selected "Division" custom field, with options: Group X, Group Y.
I want a specific person added as a Preset Approver.
I managed to find the customfield_10700 id that stores the approvers for that Approval step (different approvers for different statuses).
In my automation, if Division = Group X, I want to populate the Preset approver field with the reporter (as an example):
{
"fields": {
"customfield_10700": [
{
"value": "<accountid>"
}
]
}
}Where <accountid> is the approver's account id.
In my testing, if an approver is already in this custom field and I run this automation, the current approver is removed, but the new approver isn't added. The automation runs without reported errors.
Would love some help!
