feat(world-vercel): support new env vars for Vercel Deployment Protection

[TooTallNate]

Summary

Adds two new environment variables to @workflow/world-vercel for use with Vercel Deployment Protection.

VERCEL_WORKFLOW_SERVER_PROTECTION_BYPASS

When set, the value is sent as the x-vercel-protection-bypass header on every outbound HTTP request made by the Vercel world (via makeRequest, the streamer, refs, and direct api.vercel.com calls in resolve-latest-deployment.ts and encryption.ts).

Needed because workflow-server is getting Vercel Deployment Protection enabled, so external callers need a way to authenticate bypass.

VERCEL_WORKFLOW_SERVER_URL

Replaces the need to edit source to change the workflow-server URL. When set, requests bypass the default production host (https://vercel-workflow.com) and use the override instead. When going through the api.vercel.com/v1/workflow proxy, the value is forwarded via the x-vercel-workflow-api-url header so the proxy routes accordingly.

The existing inline WORKFLOW_SERVER_URL_OVERRIDE const is preserved as an empty-string literal so external CI rewrite tooling continues to work unmodified; the inline const wins over the env var when non-empty.

Implementation

• New getProtectionBypassHeader() helper in utils.ts returns the bypass header when the env var is set.
• getHeaders() applies the bypass header automatically (covers makeRequest, streamer, refs).
• Direct api.vercel.com fetches in resolve-latest-deployment.ts and encryption.ts spread the helper into their headers.
• New getWorkflowServerUrlOverride() function prefers the inline const, falls back to VERCEL_WORKFLOW_SERVER_URL.
• The bypass header passes through the api.vercel.com/v1/workflow proxy transparently — http-proxy-middleware forwards all request headers by default, so no proxy-side changes needed.

Testing

• pnpm --filter @workflow/world-vercel typecheck ✅
• pnpm --filter @workflow/world-vercel test — 79 tests pass ✅

Pull request overview

Adds support in @workflow/world-vercel for sending Vercel Deployment Protection bypass credentials via WORKFLOW_VERCEL_PROTECTION_BYPASS, ensuring outbound requests can access protected preview/production deployments.

Changes:

• Introduces getProtectionBypassHeader() helper to conditionally produce the x-vercel-protection-bypass header.
• Injects the bypass header into the shared getHeaders() path (covers makeRequest/streamer/refs).
• Spreads the bypass header into direct fetch() calls in resolve-latest-deployment.ts and encryption.ts.

Summary

Adds two new environment variables to @workflow/world-vercel for use with Vercel Deployment Protection.

VERCEL_WORKFLOW_SERVER_PROTECTION_BYPASS

When set, the value is sent as the x-vercel-protection-bypass header on every outbound HTTP request made by the Vercel world (via makeRequest, the streamer, refs, and direct api.vercel.com calls in resolve-latest-deployment.ts and encryption.ts).

Needed because workflow-server is getting Vercel Deployment Protection enabled, so external callers need a way to authenticate bypass.

VERCEL_WORKFLOW_SERVER_URL

Replaces the need to edit source to change the workflow-server URL. When set, requests bypass the default production host (https://vercel-workflow.com) and use the override instead. When going through the api.vercel.com/v1/workflow proxy, the value is forwarded via the x-vercel-workflow-api-url header so the proxy routes accordingly.

The existing inline WORKFLOW_SERVER_URL_OVERRIDE const is preserved as an empty-string literal so external CI rewrite tooling continues to work unmodified; the inline const wins over the env var when non-empty.

Implementation

• New getProtectionBypassHeader() helper in utils.ts returns the bypass header when the env var is set.
• getHeaders() applies the bypass header automatically (covers makeRequest, streamer, refs).
• Direct api.vercel.com fetches in resolve-latest-deployment.ts and encryption.ts spread the helper into their headers.
• New getWorkflowServerUrlOverride() function prefers the inline const, falls back to VERCEL_WORKFLOW_SERVER_URL.
• The bypass header passes through the api.vercel.com/v1/workflow proxy transparently — http-proxy-middleware forwards all request headers by default, so no proxy-side changes needed.

Testing

• pnpm --filter @workflow/world-vercel typecheck ✅
• pnpm --filter @workflow/world-vercel test — 79 tests pass ✅

Pull request overview

Adds support in @workflow/world-vercel for sending Vercel Deployment Protection bypass credentials via WORKFLOW_VERCEL_PROTECTION_BYPASS, ensuring outbound requests can access protected preview/production deployments.

Changes:

• Introduces getProtectionBypassHeader() helper to conditionally produce the x-vercel-protection-bypass header.
• Injects the bypass header into the shared getHeaders() path (covers makeRequest/streamer/refs).
• Spreads the bypass header into direct fetch() calls in resolve-latest-deployment.ts and encryption.ts.

Summary

Adds two new environment variables to @workflow/world-vercel for use with Vercel Deployment Protection.

VERCEL_WORKFLOW_SERVER_PROTECTION_BYPASS

When set, the value is sent as the x-vercel-protection-bypass header on every outbound HTTP request made by the Vercel world (via makeRequest, the streamer, refs, and direct api.vercel.com calls in resolve-latest-deployment.ts and encryption.ts).

Needed because workflow-server is getting Vercel Deployment Protection enabled, so external callers need a way to authenticate bypass.

VERCEL_WORKFLOW_SERVER_URL

Replaces the need to edit source to change the workflow-server URL. When set, requests bypass the default production host (https://vercel-workflow.com) and use the override instead. When going through the api.vercel.com/v1/workflow proxy, the value is forwarded via the x-vercel-workflow-api-url header so the proxy routes accordingly.

The existing inline WORKFLOW_SERVER_URL_OVERRIDE const is preserved as an empty-string literal so external CI rewrite tooling continues to work unmodified; the inline const wins over the env var when non-empty.

Implementation

• New getProtectionBypassHeader() helper in utils.ts returns the bypass header when the env var is set.
• getHeaders() applies the bypass header automatically (covers makeRequest, streamer, refs).
• Direct api.vercel.com fetches in resolve-latest-deployment.ts and encryption.ts spread the helper into their headers.
• New getWorkflowServerUrlOverride() function prefers the inline const, falls back to VERCEL_WORKFLOW_SERVER_URL.
• The bypass header passes through the api.vercel.com/v1/workflow proxy transparently — http-proxy-middleware forwards all request headers by default, so no proxy-side changes needed.

Testing

• pnpm --filter @workflow/world-vercel typecheck ✅
• pnpm --filter @workflow/world-vercel test — 79 tests pass ✅

Pull request overview

Adds support in @workflow/world-vercel for sending Vercel Deployment Protection bypass credentials via WORKFLOW_VERCEL_PROTECTION_BYPASS, ensuring outbound requests can access protected preview/production deployments.

Changes:

• Introduces getProtectionBypassHeader() helper to conditionally produce the x-vercel-protection-bypass header.
• Injects the bypass header into the shared getHeaders() path (covers makeRequest/streamer/refs).
• Spreads the bypass header into direct fetch() calls in resolve-latest-deployment.ts and encryption.ts.

Summary

Adds two new environment variables to @workflow/world-vercel for use with Vercel Deployment Protection.

VERCEL_WORKFLOW_SERVER_PROTECTION_BYPASS

When set, the value is sent as the x-vercel-protection-bypass header on every outbound HTTP request made by the Vercel world (via makeRequest, the streamer, refs, and direct api.vercel.com calls in resolve-latest-deployment.ts and encryption.ts).

Needed because workflow-server is getting Vercel Deployment Protection enabled, so external callers need a way to authenticate bypass.

VERCEL_WORKFLOW_SERVER_URL

Replaces the need to edit source to change the workflow-server URL. When set, requests bypass the default production host (https://vercel-workflow.com) and use the override instead. When going through the api.vercel.com/v1/workflow proxy, the value is forwarded via the x-vercel-workflow-api-url header so the proxy routes accordingly.

The existing inline WORKFLOW_SERVER_URL_OVERRIDE const is preserved as an empty-string literal so external CI rewrite tooling continues to work unmodified; the inline const wins over the env var when non-empty.

Implementation

• New getProtectionBypassHeader() helper in utils.ts returns the bypass header when the env var is set.
• getHeaders() applies the bypass header automatically (covers makeRequest, streamer, refs).
• Direct api.vercel.com fetches in resolve-latest-deployment.ts and encryption.ts spread the helper into their headers.
• New getWorkflowServerUrlOverride() function prefers the inline const, falls back to VERCEL_WORKFLOW_SERVER_URL.
• The bypass header passes through the api.vercel.com/v1/workflow proxy transparently — http-proxy-middleware forwards all request headers by default, so no proxy-side changes needed.

Testing

• pnpm --filter @workflow/world-vercel typecheck ✅
• pnpm --filter @workflow/world-vercel test — 79 tests pass ✅

Pull request overview

Adds support in @workflow/world-vercel for sending Vercel Deployment Protection bypass credentials via WORKFLOW_VERCEL_PROTECTION_BYPASS, ensuring outbound requests can access protected preview/production deployments.

Changes:

• Introduces getProtectionBypassHeader() helper to conditionally produce the x-vercel-protection-bypass header.
• Injects the bypass header into the shared getHeaders() path (covers makeRequest/streamer/refs).
• Spreads the bypass header into direct fetch() calls in resolve-latest-deployment.ts and encryption.ts.

Reviewed changes

Copilot reviewed 4 out of 4 changed files in this pull request and generated 4 comments.

Adds two new environment variables to @workflow/world-vercel for use with Vercel Deployment Protection.

VERCEL_WORKFLOW_SERVER_PROTECTION_BYPASS

When set, the value is sent as the x-vercel-protection-bypass header on every outbound HTTP request made by the Vercel world (via makeRequest, the streamer, refs, and direct api.vercel.com calls in resolve-latest-deployment.ts and encryption.ts).

Needed because workflow-server is getting Vercel Deployment Protection enabled, so external callers need a way to authenticate bypass.

VERCEL_WORKFLOW_SERVER_URL

Replaces the need to edit source to change the workflow-server URL. When set, requests bypass the default production host (https://vercel-workflow.com) and use the override instead. When going through the api.vercel.com/v1/workflow proxy, the value is forwarded via the x-vercel-workflow-api-url header so the proxy routes accordingly.

The existing inline WORKFLOW_SERVER_URL_OVERRIDE const is preserved as an empty-string literal so external CI rewrite tooling continues to work unmodified; the inline const wins over the env var when non-empty.

Implementation

• New getProtectionBypassHeader() helper in utils.ts returns the bypass header when the env var is set.
• getHeaders() applies the bypass header automatically (covers makeRequest, streamer, refs).
• Direct api.vercel.com fetches in resolve-latest-deployment.ts and encryption.ts spread the helper into their headers.
• New getWorkflowServerUrlOverride() function prefers the inline const, falls back to VERCEL_WORKFLOW_SERVER_URL.
• The bypass header passes through the api.vercel.com/v1/workflow proxy transparently — http-proxy-middleware forwards all request headers by default, so no proxy-side changes needed.

Testing

• pnpm --filter @workflow/world-vercel typecheck ✅
• pnpm --filter @workflow/world-vercel test — 79 tests pass ✅

Pull request overview

Adds support in @workflow/world-vercel for sending Vercel Deployment Protection bypass credentials via WORKFLOW_VERCEL_PROTECTION_BYPASS, ensuring outbound requests can access protected preview/production deployments.

Changes:

• Introduces getProtectionBypassHeader() helper to conditionally produce the x-vercel-protection-bypass header.
• Injects the bypass header into the shared getHeaders() path (covers makeRequest/streamer/refs).
• Spreads the bypass header into direct fetch() calls in resolve-latest-deployment.ts and encryption.ts.

Summary

Adds two new environment variables to @workflow/world-vercel for use with Vercel Deployment Protection.

VERCEL_WORKFLOW_SERVER_PROTECTION_BYPASS

When set, the value is sent as the x-vercel-protection-bypass header on every outbound HTTP request made by the Vercel world (via makeRequest, the streamer, refs, and direct api.vercel.com calls in resolve-latest-deployment.ts and encryption.ts).

Needed because workflow-server is getting Vercel Deployment Protection enabled, so external callers need a way to authenticate bypass.

VERCEL_WORKFLOW_SERVER_URL

Replaces the need to edit source to change the workflow-server URL. When set, requests bypass the default production host (https://vercel-workflow.com) and use the override instead. When going through the api.vercel.com/v1/workflow proxy, the value is forwarded via the x-vercel-workflow-api-url header so the proxy routes accordingly.

The existing inline WORKFLOW_SERVER_URL_OVERRIDE const is preserved as an empty-string literal so external CI rewrite tooling continues to work unmodified; the inline const wins over the env var when non-empty.

Implementation

• New getProtectionBypassHeader() helper in utils.ts returns the bypass header when the env var is set.
• getHeaders() applies the bypass header automatically (covers makeRequest, streamer, refs).
• Direct api.vercel.com fetches in resolve-latest-deployment.ts and encryption.ts spread the helper into their headers.
• New getWorkflowServerUrlOverride() function prefers the inline const, falls back to VERCEL_WORKFLOW_SERVER_URL.
• The bypass header passes through the api.vercel.com/v1/workflow proxy transparently — http-proxy-middleware forwards all request headers by default, so no proxy-side changes needed.

Testing

• pnpm --filter @workflow/world-vercel typecheck ✅
• pnpm --filter @workflow/world-vercel test — 79 tests pass ✅

Pull request overview

Adds support in @workflow/world-vercel for sending Vercel Deployment Protection bypass credentials via WORKFLOW_VERCEL_PROTECTION_BYPASS, ensuring outbound requests can access protected preview/production deployments.

Changes:

• Introduces getProtectionBypassHeader() helper to conditionally produce the x-vercel-protection-bypass header.
• Injects the bypass header into the shared getHeaders() path (covers makeRequest/streamer/refs).
• Spreads the bypass header into direct fetch() calls in resolve-latest-deployment.ts and encryption.ts.

Summary

Adds two new environment variables to @workflow/world-vercel for use with Vercel Deployment Protection.

VERCEL_WORKFLOW_SERVER_PROTECTION_BYPASS

When set, the value is sent as the x-vercel-protection-bypass header on every outbound HTTP request made by the Vercel world (via makeRequest, the streamer, refs, and direct api.vercel.com calls in resolve-latest-deployment.ts and encryption.ts).

Needed because workflow-server is getting Vercel Deployment Protection enabled, so external callers need a way to authenticate bypass.

VERCEL_WORKFLOW_SERVER_URL

Replaces the need to edit source to change the workflow-server URL. When set, requests bypass the default production host (https://vercel-workflow.com) and use the override instead. When going through the api.vercel.com/v1/workflow proxy, the value is forwarded via the x-vercel-workflow-api-url header so the proxy routes accordingly.

The existing inline WORKFLOW_SERVER_URL_OVERRIDE const is preserved as an empty-string literal so external CI rewrite tooling continues to work unmodified; the inline const wins over the env var when non-empty.

Implementation

• New getProtectionBypassHeader() helper in utils.ts returns the bypass header when the env var is set.
• getHeaders() applies the bypass header automatically (covers makeRequest, streamer, refs).
• Direct api.vercel.com fetches in resolve-latest-deployment.ts and encryption.ts spread the helper into their headers.
• New getWorkflowServerUrlOverride() function prefers the inline const, falls back to VERCEL_WORKFLOW_SERVER_URL.
• The bypass header passes through the api.vercel.com/v1/workflow proxy transparently — http-proxy-middleware forwards all request headers by default, so no proxy-side changes needed.

Testing

• pnpm --filter @workflow/world-vercel typecheck ✅
• pnpm --filter @workflow/world-vercel test — 79 tests pass ✅

Pull request overview

Adds support in @workflow/world-vercel for sending Vercel Deployment Protection bypass credentials via WORKFLOW_VERCEL_PROTECTION_BYPASS, ensuring outbound requests can access protected preview/production deployments.

Changes:

• Introduces getProtectionBypassHeader() helper to conditionally produce the x-vercel-protection-bypass header.
• Injects the bypass header into the shared getHeaders() path (covers makeRequest/streamer/refs).
• Spreads the bypass header into direct fetch() calls in resolve-latest-deployment.ts and encryption.ts.

Summary

Adds two new environment variables to @workflow/world-vercel for use with Vercel Deployment Protection.

VERCEL_WORKFLOW_SERVER_PROTECTION_BYPASS

When set, the value is sent as the x-vercel-protection-bypass header on every outbound HTTP request made by the Vercel world (via makeRequest, the streamer, refs, and direct api.vercel.com calls in resolve-latest-deployment.ts and encryption.ts).

Needed because workflow-server is getting Vercel Deployment Protection enabled, so external callers need a way to authenticate bypass.

VERCEL_WORKFLOW_SERVER_URL

Replaces the need to edit source to change the workflow-server URL. When set, requests bypass the default production host (https://vercel-workflow.com) and use the override instead. When going through the api.vercel.com/v1/workflow proxy, the value is forwarded via the x-vercel-workflow-api-url header so the proxy routes accordingly.

The existing inline WORKFLOW_SERVER_URL_OVERRIDE const is preserved as an empty-string literal so external CI rewrite tooling continues to work unmodified; the inline const wins over the env var when non-empty.

Implementation

• New getProtectionBypassHeader() helper in utils.ts returns the bypass header when the env var is set.
• getHeaders() applies the bypass header automatically (covers makeRequest, streamer, refs).
• Direct api.vercel.com fetches in resolve-latest-deployment.ts and encryption.ts spread the helper into their headers.
• New getWorkflowServerUrlOverride() function prefers the inline const, falls back to VERCEL_WORKFLOW_SERVER_URL.
• The bypass header passes through the api.vercel.com/v1/workflow proxy transparently — http-proxy-middleware forwards all request headers by default, so no proxy-side changes needed.

Testing

• pnpm --filter @workflow/world-vercel typecheck ✅
• pnpm --filter @workflow/world-vercel test — 79 tests pass ✅

Pull request overview

Adds support in @workflow/world-vercel for sending Vercel Deployment Protection bypass credentials via WORKFLOW_VERCEL_PROTECTION_BYPASS, ensuring outbound requests can access protected preview/production deployments.

Changes:

• Introduces getProtectionBypassHeader() helper to conditionally produce the x-vercel-protection-bypass header.
• Injects the bypass header into the shared getHeaders() path (covers makeRequest/streamer/refs).
• Spreads the bypass header into direct fetch() calls in resolve-latest-deployment.ts and encryption.ts.

Reviewed changes

Copilot reviewed 4 out of 4 changed files in this pull request and generated 4 comments.
