HOW CAN I SEARCH FOR PRODUCTS FROM SKU

Topic summary

Attempt to search Shopify products by variant SKU (Stock Keeping Unit) via the search bar in the Dawn 15.2.0 theme. The user is calling the Shopify API with fetch and testing the same request in Postman.

Problem: Both methods fail with an “invalid API key or access token” error, despite entering credentials they believe are correct.

Status: No solutions or workarounds provided yet; user requests help. The discussion remains open with the key question of how to authenticate and query by variant SKU successfully.
