You can achieve this by using the HTTP Proxie and calling the Alumio API itself as the ‘different system’
Have your HTTP Proxie do a POST Request to the Alumio API endpoint ‘https://uat-ledloket.alumio.com/api/v1/transformers/execute’ with the following body:
{
"entities": [
{
"Some_key": "Your Data",
"Another_Key": "More Data"
}
],
"specification": {
"prototype": "chain",
"parameters": {
"transformers": [
"transformer-identifier"
]
}
}
}
‘entities’ should contain the input data for the transformer
