Bad Request for the example curl request from the Shopify documentation for Product Variants

[paulls]

Hello,

When we try to follow the example “Get the first three product variants updated after the specified date” from the Shopify documentation: https://shopify.dev/api/admin-graphql/2022-01/queries/productVariants#examples-Get_the_first_three_product_variants_updated_after_the_specified_date

we receive the “Bad Request” error.

The request we try is:

curl -X POST https://your-development-store.myshopify.com/admin/api/2022-01/graphql.json -H 'Content-Type: application/json' -H 'X-Shopify-Access-Token: {access_token}' -d '{"query": "query { productVariants(first: 3, query: "updated_at:>2021-01-01") { edges { node { id title price updatedAt inventoryQuantity product { id title } } } } }"}'

of course with replaced {access_token} part and our website’s url.

When we modify the request a bit it then returns correct data:

curl -X POST https://your-development-store.myshopify.com/admin/api/2022-01/graphql.json -H 'Content-Type: application/graphql' -H 'X-Shopify-Access-Token: {access_token}' -d '{productVariants(first: 3, query: "updated_at:>2021-01-01") { edges { node { id title price updatedAt inventoryQuantity product { id title } } } } }'

Could you please check why the example from Shopify’s documentation doesn’t work?

We build an integration and part of our logic is to check whether a product with particular barcode already exists in Shopify before creating a new product, for this we use the following request which is based on the above example:

curl -X POST https://your-development-store.myshopify.com/admin/api/2022-01/graphql.json -H 'Content-Type: application/graphql' -H 'X-Shopify-Access-Token: {access_token}' -d '{productVariants(first: 10,query: "barcode:XXX") {edges {node {id sku barcode inventoryItem{id} product{id}}}}}'

It seemed to work fine until one day we realised some products are duplicated in Shopify. We found out that the above call works fine like in 90% of time but sometimes it returns data for some products but not all, even if the barcode is exactly the same. Is there some known bug related to the issue I described? Perhaps you can suggest a different api endpoint/request we should use to determine if a product with particular barcode already exists in Shopify?

Thanks,

Paul

Hi @paulls

Thanks for highlighting the issue with the dev doc cURL example. It appears to be a difficulty with defining the query parameter to be a string literal "updated_at:>2021-01-01", and could be formatted a bit better:

curl -X POST \
https://your-development-store.myshopify.com/admin/api/2022-01/graphql.json \
-H 'Content-Type: application/json' \
-H 'X-Shopify-Access-Token: {access_token}' \
-d '{"query":"query ($query: String){ productVariants(first: 5, query: $query) {       nodes { id } } }","variables":{"query":"updated_at:>2021-01-01"}}'

Generally, the best way to flag any errors with the dev docs team is via the feedback section below the examples.

I would also recommend reviewing our guide to the search syntax to apply the barcode filter on the variants. With cURL, it will likely look similar to the below:

curl -X POST \
https://your-development-store.myshopify.com/admin/api/2022-01/graphql.json \
-H 'Content-Type: application/json' \
-H 'X-Shopify-Access-Token: {access_token}' \
-d '{"query":"query ($query: String){ productVariants(first: 5, query: $query) {       nodes { id } } }","variables":{"query":"barcode:xyz"}}'

For complex requests, it may be helpful to use a client like Postman/Insomnia or one of our API libraries in your integration’s native language, rather than a cURL request. If you still run into issues with the filter, please reach out via your partner dashboard with an example variant/shop so that we can take a closer look with your authenticated permissions.

Hope that helps!
