GraphQL image uploads: presignedPost is deprecated

For developers using our GraphQL API

createImageUploadURL now returns a new presignedPut field alongside the existing presignedPost. presignedPost is deprecated and scheduled for removal on September 7, 2026.

Move your integration to presignedPut: sign one PUT request instead of a multi-field POST, then call confirmImageUpload(key) once the upload finishes.

mutation {
  createImageUploadURL(input: { contentType: "image/png" }) {
    presignedPut { url cdnUrl key }
  }
}

PUT your image bytes to url with a matching Content-Type header, then call confirmImageUpload(input: { key: key }) and use the returned cdnUrl.

If you use gql-skill or the publish-github-action, update to the latest version before the removal date.
