How is GraphQL encoded in the generated PowerShell?

GraphQL queries are treated as JSON payloads with the { query, variables } shape intact.

Does it preserve Content-Type?

Yes. The Content-Type header is honored and matched against the body so serialization stays consistent.

Is anything uploaded?

No. Parsing and generation happen entirely in your browser.

Send GraphQL with cURL in PowerShell

Paste a curl command that sends GraphQL and get idiomatic PowerShell code. We pick the right serialization for Invoke-RestMethod and set the correct Content-Type.

Quick answer

To convert a cURL command to PowerShell, paste it into the Toolpaper workbench below. It parses the command in your browser and emits idiomatic PowerShell code — headers, query string, request body, authentication (Bearer, Basic, API key), and cookies are all wired up automatically. No data is uploaded; conversion is fully client-side.

Example

A representative curl command for this scenario. Paste your own above to convert an exact match.

curl input

curl -X POST https://api.example.com/graphql \
  -H "Content-Type: application/json" \
  -d '{"query":"{ viewer { id name } }"}'

Implementation notes

Content-Type is detected from -H headers first, then inferred from the body shape when the header is missing.
GraphQL payloads keep their { query, variables, operationName } shape so persisted-query servers keep matching.
Charset directives on Content-Type (e.g. application/json; charset=utf-8) survive the round trip.

Common mistakes

Setting Content-Type manually and then also using Invoke-RestMethod's helper — you end up with duplicate headers or the wrong one wins.
Mixing form encoding with JSON headers — the server rejects with 400 and it's easy to miss in code review.
Trusting the browser DevTools "Copy as cURL" to preserve charset — it often drops it. Clean panel restores common defaults.
