Find Product by SKU

[iamakimmer]

How can I retrive a product by sku, not product id?

I also needed to know this, thankfully there is documentation on this for Magento 1.9x

Looks like the argument "productId" can be a Product ID number or a SKU. Shrugs okay then

Tried it out and it appears to work, so long as your SKU's are alpha/numeric not just number then it should be fine.

Others I read such as catalogProductAttributeMedia create seem to say to set identifierType

"product": "SKU Goes here",
"identifierType": "sku",

I keep getting 400 Bad Request so Have not been able to try yet.
