Unable to add a single line items with modifiers using Clover POS REST API - rest

Question

I am trying to add a single line item with modifiers using the Rest API. I see answers that it's not possible while adding bulk line items (the documentation for both suggests that this should be possible).
This is the request I am sending.
URL: https://sandbox.dev.clover.com/v3/merchants/MERCHANTID/orders/ORDERID/line_items
Request Type: POST
"item": {
"id":"9S1MXGERPQ7ER"
}
"modifications" : [{
"modifier" : {
"id" : "ZM8MV5X3M7R72",
"modifierGroup": {
"id" : "YC351CMAHF6AY"
}
},
"modifier" : {
"id" : "0X5A869PQT858",
"modifierGroup": {
"id" : "XZP32FHXQWKE6"
}
}
}]
The item gets created fine. but none of the modifiers are added.
I checked that creating a line item initially and then making an explicit call to the below URL to add modification works fine, but with this approach we can only add 1 modifier per call.
https://sandbox.dev.clover.com/v3/merchants/MERCHANTID/orders/ORDERID/line_items/LINEITEMID/modifications
Request:
{
"modifier" : {
"id" : "ZM8MV5X3M7R72"
}
}
With this approach we have to make multiple calls per line item based on number of modifiers selected.
Am I missing something here?

Answer 1

I have the same problem. you are missing the name and amount property of the modifier. These are required fields e.g
URL: https://sandbox.dev.clover.com/v3/merchants/MERCHANTID/orders/ORDERID/line_items
Request Type: POST
"item": {
"id":"9S1MXGERPQ7ER"
}
"modifications" : [{
"modifier" : {
"id" : "ZM8MV5X3M7R72",
"modifierGroup": {
"id" : "YC351CMAHF6AY"
},
},
"name": "yourModifierName",
"amount": "amountOfModifier"
}]
