Hello,
i try to create a new product with a fetch call. I am using php to add a new product.
But i get this error:
{“errors”:{“product”:“Required parameter missing or invalid”}}
Topic summary
Issue: Creating a product via Shopify’s Admin GraphQL API using PHP returns error: {“errors”:{“product”:“Required parameter missing or invalid”}}.
Diagnosis: The response suggests one or more required fields in the productCreate input are missing or invalid. “productCreate” is a GraphQL mutation to create products; its input has mandatory parameters defined in the 2022-10 API docs.
Requested info: The responder asked the poster to share the exact API request/code to identify which parameter is missing.
Resources provided: Links to Shopify developer docs for productCreate required arguments and a PHP code example using Shopify\Clients\Graphql (API version 2022-10) were provided. A partial PHP snippet was shown, with guidance to follow the sample.
Current status: No resolution yet. Next step is for the poster to share their code or align their request with the required productCreate input fields per the documentation to pinpoint the missing/invalid parameter.
