What it does
Canva Webhooks Events is an agent skill from jeremylongshore/tons-of-skills-marketplace. Implement Canva preview webhook verification, routing, replay defense, and idempotent processing. Use when receiving supported notification types in a non-public or otherwise eligible integration. Trigger with: "Canva webhook", "verify Canva signature", "handle Canva notification".
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Canva webhooks and keys are preview; Canva states public integrations using preview features cannot pass review.
It sits in Backend & APIs, covering Webhooks. It works with Canva. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
When your agent uses it
- Receiving supported notification types in a non-public
- Otherwise eligible integration
- With: Canva webhook
- Verify Canva signature
Example prompts
- “Canva webhook”
- “verify Canva signature”
- “handle Canva notification”
- “/canva-webhooks-events”
Requirements
- Compatibility (from SKILL.md): Canva webhooks and keys are preview; Canva states public integrations using preview features cannot pass review.
- Pre-approved tools (allowed-tools): Read, Grep, Write, Edit
Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepWriteEdit
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
canva.dev
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Canva webhooks and keys are preview; Canva states public integrations using preview features cannot pass review.
From compatibility in the SKILL.md frontmatter.
Context cost
Canva Webhooks Events loads about 1k tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 76 tokens; SKILL.md has 427 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Canva Preview Webhook Intake
Overview
Authenticate every notification with Canva's rotating public JWK set, then apply separate tenant/resource authorization and idempotency. Webhooks are outgoing-only and do not replace the Comments API for replies.
Prerequisites
- Eligible integration and explicitly approved preview use
- Controlled HTTPS callback, required scopes, and notification allowlist
- Durable idempotency store, queue, retention, and incident owner
Instructions
Step 1: Confirm eligibility
Use Read and Grep to verify current preview status, public-review posture, required collaboration plus notification-specific scopes, and enabled notification types.
Step 2: Fetch and cache keys
Use the public unauthenticated connect/keys endpoint, cache the rotating Ed25519/OKP JWK set, select by case-sensitive key ID, and refetch only once for an unknown key.
Step 3: Verify before parsing actions
Validate signature and documented token claims, reject wrong issuer/audience/time/context, cap request size, and retain no raw signed token in logs.
Step 4: Defend against replay
Create a durable idempotency key from the verified notification identity, enforce an application retention window, and acknowledge duplicates without repeating effects.
Step 5: Authorize the event
Resolve tenant, user/resource ownership, notification type, feature status, and application policy. A valid signature does not authorize a write or reply.
Step 6: Queue and process
Use Write or Edit to persist only approved fields and enqueue after verification. Return the protocol response required by the current docs without waiting on downstream side effects.
Step 7: Reconcile and observe
Record verification class, normalized type, duplicate state, queue result, redacted error, and handler version; dead-letter safely and require owner-reviewed replay.

Authentication
Canva Connect calls use Bearer access tokens obtained by a backend through OAuth 2.0 Authorization Code with SHA-256 PKCE. Request explicit least-privilege scopes, keep client secrets and tokens out of browser-visible state, and serialize refresh so the replacement single-use refresh token is stored atomically.
Tool Discipline
Use Read and Grep for discovery and evidence. Use Write or Edit only for the approved artifact, code, configuration, test, or receipt described by this workflow; do not make an unapproved Canva-side change.
Output
- Scoped decision or implementation artifact
- Redacted operation and validation receipt
- Failure, rollback, and follow-up ownership record
Examples
A verified comment notification is deduplicated and routed to an authorized tenant queue. Any response comment is sent separately through the current Comments API after its own policy check.
Error Handling
| Failure | Response |
|---|---|
| Preview is ineligible for release | Disable the webhook path |
| Key ID is unknown | Refresh keys once and fail closed if unresolved |
| Notification type is unrecognized | Quarantine metadata only and update the contract |
| Duplicate delivery arrives | Acknowledge without replaying side effects |
