Add matrix attribute with value to product



Request body

  "definitionId": "{attribute id}",
   "matrix": {
        "60869b2b6b2f07000cacff76": {
            "60869b2b6b2f07000cacff75": "First row first column value",
            "60869b4c6b2f07000cacff78": "Second row first column value"
        "60869b4c6b2f07000cacff79": {
            "60869b2b6b2f07000cacff75": "First row second column value",
            "60869b4c6b2f07000cacff78": "Second row second column value"

Use attribute id in definitionId. In the matrix property, the keys are a row and a column id's from the attribute definition.
See how to get attribute definition and value id's.  


If successful, this will result in a 201 - Created response. This means the attribute has been added to the product with the values.
