- Around line 88-92: Update the error-response branches in the GraphQL API
handler to stop sending raw err.Error() text to clients. Log each specific error
internally, then return sterile client-facing messages for both 500 responses
and the generic 400 fallbacks, covering the branches around the existing
httputil.WriteJSON calls while preserving their status codes and control flow.
In `@gateway/gateway-controller/pkg/transform/graphql.go`:
- Line 110: Update resolveUpstreamCluster and the main/sandbox upstream
transformation flow to validate API-configured destinations against the
configured backends, require HTTPS unless HTTP is explicitly enabled, and reject
loopback, private, link-local, and metadata addresses after DNS resolution at
the data-plane dial path. Add regression coverage for IP-literal and
DNS-resolved private destinations.
In `@platform-api/go.mod`:
- Line 20: Add github.com/vektah/gqlparser/v2 version v2.5.36 to the approved
dependency registry under the api-platform scope, matching the registry’s
existing entry format. Do not alter unrelated dependencies.
In `@platform-api/internal/service/graphql_api_test.go`:
- Around line 324-328: Harden fetchAndConvertGraphQLSchema by validating URL
schemes and blocking private, loopback, link-local, and cloud-metadata
destinations using resolved-IP checks at both redirect and dial time. Treat the
tenant-provided upstream.main.url as untrusted, and update the related test to
expect rejection of the httptest.Server URL.
In `@platform-api/internal/service/graphql_api.go`:
- Around line 259-286: Update fetchAndConvertGraphQLSchema to use the public
SSRF-safe dial policy that rejects loopback, private, ULA, and shared IP
addresses instead of the permissive upstream policy. Enforce the 5 MiB response
limit by reading up to one byte beyond the cap and returning an error when that
extra byte exists, rather than accepting truncated JSON.
In `@platform-api/internal/service/graphql_deployment.go`:
- Around line 580-591: Guard deployment.Status in GetGraphQLAPIDeployment before
passing it to toAPIDeploymentResponse, returning an error when it is nil; also
guard d.Status in the GetGraphQLAPIDeployments loop and skip or fail that row
instead of dereferencing it. Apply the change at
platform-api/internal/service/graphql_deployment.go lines 580-591 and 536-548.
In `@platform-api/internal/service/graphql_introspection.go`:
- Line 229: Update the introspection request flow around io.ReadAll and the
existing timeout to obtain both the inbound response limit and timeout from
config.Server, while preserving 5 MiB and 15 seconds as safe defaults when
unset. Ensure the configured limit continues to wrap resp.Body via
io.LimitReader before reading into memory, and use the configured timeout for
the request.
- Around line 202-256: Update fetchAndConvertGraphQLSchema to use the
public-only SSRF protection for upstreamURL instead of NewUpstreamFetchClient's
private/in-cluster-permitting policy. Ensure address validation rejects private
and loopback destinations for the initial request and every redirect hop,
reusing the existing public-only fetch mechanism or its address-checking
configuration.

Outside diff comments:
In `@gateway/it/suite_test.go`:
- Around line 129-133: Add features/graphql_deploy.feature and
features/graphql-api-keys.feature to defaultPaths in gateway/it/suite_test.go
alongside the existing API-key feature. Make no changes to
gateway/it/features/graphql_deploy.feature lines 19-25 or
gateway/it/features/graphql-api-keys.feature lines 28-35; they should execute
once registered, so re-run the integration suite to verify both are included.
In `@platform-api/resources/role-to-scope-mapping.yaml`:
- Around line 204-216: Update the ap_subscriber role’s scopes to include
ap:graphql_api:read so ListGraphQLAPIs and GetGraphQLAPI requests are permitted
without granting management access.
---
Minor comments:
In `@cli/src/cmd/gateway/graphqlapi/apikey/create.go`:
- Around line 123-129: Close successful HTTP response bodies by deferring
resp.Body.Close() immediately after the error check in the API-key command
flows: create.go lines 123-129, regenerate.go lines 81-87, and update.go lines
97-103. Apply the change to each command before processing or printing the
response.
In `@cli/src/cmd/gateway/graphqlapi/apikey/update.go`:
- Around line 61-63: Update the update command’s API-key input around the
updateNewAPIKey flag so plaintext keys are no longer accepted directly through
--api-key; add a secure non-echoed stdin, file-descriptor, or interactive input
path, and mark the existing --api-key plaintext option as deprecated while
preserving required validation and update behavior.
In `@cli/src/cmd/gateway/graphqlapi/get.go`:
- Around line 141-175: Update both non-200 response branches in the GraphQL API
retrieval flow, including getAPIByNameAndVersion, to return only a sterile
status-based error without appending string(body). Preserve any approved debug
logging mechanism for diagnostics, but do not expose raw gateway response bodies
through CLI errors.
In `@gateway/examples/countries-graphql-api.yaml`:
- Around line 24-29: Update the OpenAPI version pattern used for GraphQL API
configurations to accept both major-only versions such as v1 and existing
major.minor versions such as v1.0, while preserving rejection of invalid
formats. Ensure the pattern aligns with validateGraphQLAPIConfig and the version
value in the Countries configuration.
In `@gateway/gateway-controller/pkg/api/handlers/graphql_api_handler.go`:
- Around line 149-157: Update the GET, PUT, and DELETE handlers around
GetConfigByKindAndHandle to use storage.IsNotFoundError(err) for 404 responses,
while mapping all other storage errors to a generic 500 response. Preserve the
existing not-found message and ensure database or connection failures are not
reported as missing GraphQL APIs.
In `@gateway/gateway-controller/pkg/storage/sqlite_test.go`:
- Line 124: Update the schema-version statement in the SQLite test to call
storage.db.ExecContext with an appropriate test context instead of Exec,
preserving the existing PRAGMA and error handling.
In `@gateway/gateway-controller/pkg/utils/graphql_deployment.go`:
- Around line 94-98: Add validation to the spec.context checks in the deployment
validation logic to reject non-root values ending with “/”, reporting a
validation error on spec.context. Preserve the existing required and
leading-slash checks, while allowing the root context “/”.
In `@gateway/gateway-runtime/policy-engine/go.mod`:
- Line 19: Update the github.com/wso2/api-platform/sdk/core dependency from
v0.3.6 to v0.4.0 in the module configuration, preserving all other dependency
entries unchanged.
In `@gateway/it/steps_graphql.go`:
- Around line 45-52: URL-escape the GraphQL API name before inserting it into
the request path in the delete, get, and update step helpers. Add the net/url
import and use its path-segment escaping function so names containing characters
such as # reach the controller unchanged as identifiers.
In `@platform-api/internal/repository/graphql_api_test.go`:
- Around line 337-359: Update GraphQLAPIRepo.List so both query branches order
by created_at descending and uuid ascending, ensuring deterministic pagination
when timestamps tie. Preserve the existing filtering and pagination behavior.
In `@platform-api/internal/utils/graphql_multipart.go`:
- Around line 50-83: Update ParseGraphQLAPIMultipartRequest to wrap the inbound
request body with http.MaxBytesReader before ParseMultipartForm, using the
configured SDL upload ceiling plus multipart overhead as the request limit while
retaining the SDL ceiling as maxMemory. Explicitly call MultipartForm.RemoveAll
after parsing to clean up any spilled temporary files, and revise the function
comment to describe the actual bounded-body behavior rather than claiming files
are never written to disk.
In `@platform-api/resources/openapi.yaml`:
- Around line 7164-7175: Update the metadata description in the multipart schema
to state that metadata sdl and sdlUrl values are preserved when no non-empty
sdlFile part is uploaded, while a non-empty sdlFile overrides the metadata SDL
value. Keep the existing upload-field description and schema optionality
unchanged.

Nitpick comments:
In `@gateway/examples/blog-graphql-api.yaml`:
- Around line 1-9: Update the Apache license header in the blog GraphQL API
example to match the complete header used by the countries GraphQL API example,
including the WSO2 license grant and the “AS IS” disclaimer while preserving the
existing copyright and license text.
In `@gateway/gateway-controller/api/management-openapi.yaml`:
- Around line 3552-3564: Update the GraphQL API upstream schema documentation
around the upstream properties to state that GraphQLApi supports only an inline
upstream.main.url and does not support upstream.ref, since GraphQLAPIConfigData
has no upstreamDefinitions for resolution; do not add upstreamDefinitions.
In `@gateway/gateway-controller/pkg/utils/graphql_deployment.go`:
- Around line 38-43: Update the graphQLApiKind constant to derive its value from
the generated api.GraphQLAPIKindGraphQLApi constant instead of repeating the
"GraphQLApi" literal, preserving the existing parser and validator registration
in init.
In `@gateway/gateway-controller/tests/integration/schema_test.go`:
- Line 107: Update the ResourceTypeTablesExist schema assertion to include
graphql_apis alongside the existing resource tables, ensuring every supported
dialect is verified for the new table.
In `@gateway/it/features/graphql_deploy.feature`:
- Around line 216-222: Update the “List GraphQL APIs when none exist” scenario
to query using a unique displayName filter and assert the filtered result is
empty, rather than asserting the global GraphQL API count is zero. Preserve the
authentication, success, and valid-JSON checks while removing the dependency on
unrelated gateway state.
In `@platform-api/internal/utils/graphql_multipart.go`:
- Around line 60-66: Update the FormFile error handling in the multipart parsing
function to allow metadata-only requests only when the error is
http.ErrMissingFile; propagate any other error, including malformed multipart
parts, to the caller instead of returning metadata without SDL. Use errors.Is
for the distinction and add the required errors import.

Purpose
Adds first-class support for GraphQL as a managed API kind across the platform, matching the existing capabilities REST APIs already have. Previously, exposing a GraphQL backend through the gateway required treating it as a generic REST API, which meant no purpose-built handling for GraphQL's single-endpoint, single-route shape (one POST route regardless of query/mutation), no gateway-controller or control-plane CRUD for it, no API key management, and no CLI support. This closes that gap end-to-end: gateway-only proxying, control-plane management, API key lifecycle, and CLI tooling.
Resolves #3195
