Any examples on how to use requisition_lists API Endpoint?

Question

ORIGINAL POST

---

Trying to use the save requisition list REST API endpoint. The API docs are not very clear on what the values should be and currently don't have access to the B2B module code to see what it exactly needs for the JSON input.

So, has anyone used this endpoint before? What would be a working example JSON? Am I even supposed to use this endpoint?

Doc link: https://devdocs.magento.com/redoc/2.3/async-admin-rest-api.html#operation/requisitionListRequisitionListRepositoryV1SavePost

Endpoint Example (POST method): https://magento-store.com/index.php/rest/V1/requisition_lists

Example of what I have used:

{
  "requisitionList": {
    "id": 0,
    "customer_id": 215120,
    "name": "My List A",
    "updated_at": "2019-05-06T15:49:00",
    "description": "None",
    "items": [
      {
        "id": 1,
        "sku": 20410320,
        "requisition_list_id": 0,
        "qty": 10,
        "options": [],
        "store_id": 1,
        "added_at": "2019-05-06T15:49:00",
        "extension_attributes": {}
      }
    ],
    "extension_attributes": {}
  }
}

Example Responses (2 of them):

{
    "message": "Could not save Requisition List"
}

{
    "message": "Internal Error. Details are available in Magento log file. Report ID: {error-id}"
}

UPDATE

---

It seems that not all the JSON fields are required as pointed out in the comments. I am now able to update an existing requisition list if I have the requisition list ID. I guess now does anyone know how to create a brand new list for a customer?

Request:

{
  "requisitionList": {
    "id":755,
    "customer_id": 215120,
    "name": "My List E",
    "items": [
      {
        "sku": 16740700,
        "qty": 3,
        "store_id": 1
      }
    ]
  }
}

Response:

{
    "id": 755,
    "customer_id": null,
    "name": "My List E",
    "updated_at": "1557246976",
    "description": null,
    "items": [
        {
            "id": 1316,
            "sku": "16740700",
            "requisition_list_id": 755,
            "qty": 3,
            "options": [],
            "store_id": 1,
            "added_at": null
        }
    ]
}

Answer 1

seems like its overriding customer_id:

<parameter name="requisitionList.customer_id" force="true">%customer_id</parameter>

see: \Magento\Webapi\Controller\Rest\ParamOverriderCustomerId::getOverriddenValue

it will not work for admin rest api user, its only for end customers
