[Create Product API error "product_sales_price_type_id is invalid"]

Hello, I'm trying to create product in the Sage Accounting using the API (https://developer.sage.com/accounting/reference/products-services/#tag/Products/operation/postProducts)
I'm getting error "The product_sales_price_type_id is invalid." There is no field named "product_sales_price_type_id" in the create product docs.

Where should I add "product_sales_price_type_id"?
Is the developer docs up to date?

My request is:

{
   "product": {
      "active": true,
      "cost_price": 84,
      "description": "Test Product Description",
      "purchase_ledger_account_id": null,
      "sales_ledger_account_id": null,
      "purchase_tax_rate_id": "GB_STANDARD",
      "sales_tax_rate_id": "GB_STANDARD",
      "sales_prices": [
         {
            "price": 100,
            "price_includes_tax": false,
         }
      ],
   }
}

 

[Sage Accounting Categories API]

I can add categories under the Products & Services -> Manage Categories menu in the Sage Accounting dashboard but I couldn't find how to get categories in the developer API docs.
Is there any way to get all categories using the API? (https://developer.sage.com/accounting/reference/)

Thanks.

[Getting "Authorise Application Error"]

You callback url in the authorization request must be same with your app's callback url. Otherwise it's giving an error.

I used `state` parameter to send extra data

[Send extra parameter via callback url]

Hello, I want to pass user id parameter to my server after they authenticate sage account with my app. Because my users are using same sage app so I need to know which user authenticated.

I tried to add parameter in authorization request url:
https://www.sageone.com/oauth2/auth/central?client_id={{client_id}}&country=GB&filter=apiv3.1&redirect_uri={{redirect_url}}&response_type=code&scope=full_access&user_id=123

It is not working. The sage backend deletes extra parameters in the url, the user_id parameter is not transferring to the callback.

I tried to add parameter to callback url
redirect_url = url_encoded(http://........com/callback?user_id=123)
 https://www.sageone.com/oauth2/auth/central?client_id={{client_id}}&country=GB&filter=apiv3.1&redirect_uri={{redirect_url}}&response_type=code&scope=full_access

I tried to change callback url;
redirect_url = url_encoded(http://........com/callback/123)
 https://www.sageone.com/oauth2/auth/central?client_id={{client_id}}&country=GB&filter=apiv3.1&redirect_uri={{redirect_url}}&response_type=code&scope=full_access

but when I change callback url sage auth page giving error "Authorize Application Error" It's not working.

Is there any way to this? I want to add parameter to authorization request url and read the parameter in the callback.
