Price List ID

I am trying to setup a API mutation that updates our one and only B2B price list.

I currently have this json:

{
“priceListId”: “gid://shopify/PriceList/44513689829”,
“input”: {
“quantityPriceBreaksToAdd”: [
{
“variantId”: “{{getProductVariantDataForeachitem.id}}”,
“price”: {
“amount”: “{{getProductVariantDataForeachitem.price | times: 9 | divided_by: 100 }}”,
“currencyCode”: “USD”
},
“minimumQuantity”: 0
}
],
“quantityPriceBreaksToDelete”: ,
“quantityRulesToAdd”: [
{
“increment”: 1,
“maximum”: 1000,
“minimum”: 10,
“variantId”: “{{getProductVariantDataForeachitem.id}}”
}
],
“quantityRulesToDeleteByVariantId”: ,
“pricesToAdd”: [
{
“variantId”: “{{getProductVariantDataForeachitem.id}}”,
“price”: {
“amount”: “{{getProductVariantDataForeachitem.price}}”,
“currencyCode”: “USD”
},
“compareAtPrice”: {
“amount”: “{{getProductVariantDataForeachitem.compareAtPrice}}”,
“currencyCode”: “USD”
}
}
],
“pricesToDeleteByVariantId”:
}
}

However, I am getting a response of Price List cant be found.

I may be using the wrong ID.

Can someone assist me in finding the ID for my one and only B2B price list?
