Magento 2.3.4 Add custom product attribute value (text-swatch) via REST API

Question

Using Postman, with the following GET request I receive data from my custom product attribute:
rest/V1/products/attributes?&searchCriteria[filterGroups][0][filters][0][field]=attribute_id&searchCriteria[filterGroups][0][filters][0][value]=580

The response looks like this:

"options": [
 {
 "label": " ",
 "value": ""
 },
 {
 "label": "Label 1",
 "value": "16594"
 },
 {
 "label": "Label 2",
 "value": "16597"
 },

Now I need to add a new attribute value including a label and the description.

Here it says it would be possible (now): https://devdocs.magento.com/guides/v2.3/release-notes/release-notes-2-3-4-open-source.html

Answer 1

you can see all all API list in your magento instance by below endpoint.

yourMagento/swagger

ref: https://devdocs.magento.com/guides/v2.3/rest/generate-local.html

enter image description here

on that interface you can pass your access token and get all list of available api request with example.

for your request you need to pass below params in post request.

Request Endpoint: /V1/products/attributes/{attributeCode}/options

Params:

{
 "option": {
 "label": "string",
 "value": "string",
 "sort_order": 0,
 "is_default": true,
 "store_labels": [
 {
 "store_id": 0,
 "label": "string"
 }
 ]
 }
}

Hope this solution help you to complete you task.
