Product doesn't show on website when adding it with REST

[rklerck]

We're trying to load our categories and products through REST. Everything is added nicely and is visible in the backend, but it doesn't appear on the website. The option "Display Out of Stock Products" is put on "Yes".

After saving the product in the admin OR re-enabling it in the admin, it does show up!

Steps to reproduce:

• Add category (REST or admin, doesn't matter)
• Add product with REST:

url: magento2/rest/V1/products

{
"product": {
"sku": "TEST",
"name": "TEST",
"visibility": 4,
"type_id": "simple",
"price": 3.62,
"status": 1,
"attribute_set_id": 4,
"custom_attributes": [
{
"attribute_code": "description",
"value": "TEST"
}
]
}
}

• Add product link with REST:

url: magento2/rest/V1/categories/[CATEGORY_ID]/products

{
"productLink": {
"sku": "TEST",
"category_id": [CATEGORY_ID]
}
}

After there steps the product is NOT visible on the website!

When running the indexer, by a index on schedule, this one also works fine.
Not sure if it works when the indexes are on update on save.
