Associate product as line item to deal

[konyaev]

How can I associate product as line item to deal?

Tried this way 

curl --request POST \
  --url 'https://api.hubapi.com/crm/v3/associations/deal/product/batch/create?hapikey=q1w2e3' \
  --header 'content-type: application/json' \
  --data '{
  "inputs": [
    {
      "from": {
        "id": "1"
      },
      "to": {
        "id": "2"
      },
      "type": "line_item_to_deal"
    }
  ]
}'

and got next error:

{
  "status": "COMPLETE",
  "results": [],
  "numErrors": 1,
  "errors": [
    {
      "status": "error",
      "category": "VALIDATION_ERROR",
      "subCategory": "crm.associations.INVALID_ASSOCIATION_TYPE",
      "message": "line_item_to_deal is not a valid association type between deals and products",
      "context": {
        "type": [
          "line_item_to_deal"
        ],
        "fromObjectType": [
          "deals"
        ],
        "toObjectType": [
          "products"
        ]
      }
    }
  ],
  "startedAt": "2022-07-12T18:04:25.631Z",

}

Hey, @konyaev Is this still occurring for you? 👋 

I recreated your steps, and I am getting a successful response. Here's what I did:

• I followed this guide from @himanshurauthan on how to generate a Product and Line Item via the API 
• I used the v3 endpoint from your original post 
  

  POST /crm/v3/associations/{fromObjectType}/{toObjectType}/batch/create​

• Here's my request and response:
  

  curl --request POST \
    --url https://api.hubapi.com/crm/v3/associations/Line_items/Deal/batch/create \
    --header 'authorization: Bearer NOPE' \
    --header 'content-type: application/json' \
    --data '{
    "inputs": [
      {
        "from": {
          "id": "3389121391"
        },
        "to": {
          "id": "9475998565"
        },
        "type": "line_item_to_deal"
      }
    ]
  }'​

  
  

  HTTP 201
  
  {
    "status": "COMPLETE",
    "results": [
      {
        "from": {
          "id": "3389121391"
        },
        "to": {
          "id": "9475998565"
        },
        "type": "line_item_to_deal"
      },
      {
        "from": {
          "id": "9475998565"
        },
        "to": {
          "id": "3389121391"
        },
        "type": "deal_to_line_item"
      }
    ],
    "startedAt": "2022-07-13T21:50:33.210Z",
    "completedAt": "2022-07-13T21:50:33.266Z"
  }​

• I think the difference is you used:
  

  "fromObjectType": [
            "deals"
          ],
  "toObjectType": [
            "products"​

  and I used Line_items and Deals:
  
  

  

I hope this is helpful in getting you on your way.

Happy coding! — Jaycee
