How to pass parameters to json via additionalParameters

[mr2d2]

Hello!

I am setting up a workflow. Action = Run Service Action
How to pass parameters to json via additionalParameters.
This works, but only if you specify the data in advance.

{
    "jsonchat_id": "123"
}

I want to send the value of a variable.
For example, I want to send a description.

{
    "jsonchat_id": {description}
}

Thanks!

Hello

Second parameter in your service is $entity. With this variable you can get need values

$entity->get('description');

Additional Parameters can contain only valid json data.

Thanks!

//$entity is Opportnity, for example
$account = $entity->get('account');
if ($account) {
$account->get('assignedUser');
}

I can not get the field of a related entity.
For example:
a field that belongs to "assignedUser"
$account->get('assignedUser.myField'); it does not work

[mr2d2]

$user = $entity->get('user');
if ($user) {
$user->get('myField');
}
it does not work

Getting of link field returns object. Use get again
