JOLT apply different transformations based on success of the call - json

Question

I'm calling a rest web service and I receive the following responses depending if the call was successful or not.
Input 1:
{
"success": true,
"data": {
"series": "XX/32/V32/LM",
"number": 242,
"end_date": "31/12/2023",
"premium": "2309.68",
"premium_net": "2286.58",
"total_premium": 2494.46,
"commission": 1,
"installments": [
{
"number": 1,
"due_date": "30/12/2022",
"value": "2494.46",
"currency": "RON"
}
],
"reference_premium": 1061,
"direct_settlement_cover": 1,
"direct_settlement": 184.78,
"direct_settlement_net": 182.93,
"bm": "B0",
"exclusion_countries": [
"BY",
"IL",
"IR",
"MA",
"RUS",
"TN",
"UA"
]
},
"message": "Polița a fost emisă cu succes"
}
Input 2:
{
"success": false,
"message": "Eroare validare date",
"data": {
"pay_document": [
"Trebuie să menționați modalitatea de plată"
]
}
}
And I wrote the following operations that work individually
Success spec:
[
{
"operation": "shift",
"spec": {
"message": "body.info_message",
"data": {
"#1": "body.good_id",
"series": "body.policy_series",
"number": "body.policy_number",
"end_date": "body.policy_end_date",
"direct_settlement_cover": {
"1": {
"#Decontare directa": "clauses[0].clause_name",
"#1": "clauses[0].clause_id"
}
},
"direct_settlement": "clauses[0].premium",
"installments": {
"*": {
"number": "body.installments[&1].number",
"value": "body.installments[&1].amount",
"currency": "body.installments[&1].currency",
"due_date": "body.installments[&1].due_date"
}
}
}
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"body": {
"good_id": "=toInteger"
}
}
}
]
Error spec:
[
{
"operation": "shift",
"spec": {
"message": "body.info_message",
"data": {
"*": {
"*": "body.error_message"
}
}
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"error_message": "=join(' | ',#(1,&))"
}
}
}
]
Now I'm trying to combine those two and display the error messages if success is false or return the model to be saved. I tried to place success inside my transformation but it keeps returning null. what is the best practice in this regard...

Answer 1

You can use this spec:
I'm just adding the first shift operator and changing the data key with true and false in your code. So the final code is like the below:
[
{
"operation": "shift",
"spec": {
"*": "&",
"data": "#(1,success)"
}
},
{
"operation": "shift",
"spec": {
"message": "body.info_&",
"true": {
"#1": "body.good_id",
"series": "body.policy_&",
"number": "body.policy_&",
"end_date": "body.policy_&",
"direct_settlement_cover": {
"1": {
"#Decontare directa": "clauses[0].clause_name",
"#1": "clauses[0].clause_id"
}
},
"direct_settlement": "clauses[0].premium",
"installments": {
"*": {
"*": "body.&2[&1].&",
"value": "body.&2[&1].amount"
}
}
},
"false": {
"*": {
"*": "body.error_message"
}
}
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"good_id": "=toInteger",
"error_message": "=join(' | ',#(1,&))"
}
}
}
]
