OAuth Readiness
Back to all apps

Canva

Generated live by the research agent (Gemini), checked 2026-10-19. Setup not tested by hand.

Canva provides REST APIs using OAuth 2.0 with the Authorization Code flow and PKCE for third-party integrations. Developers can configure apps in the Developer Portal and redirect users to authorize requested scopes.

Assumes: A public app connecting external users to an AI agent product requesting scopes to read and act on user assets, folders, and designs.

The agent couldn’t establish 7 of the 7 facts that set difficulty, so it won’t guess a tier. Known hurdles put it at tier 1 or higher. Check the provider’s developer docs directly, or regenerate later.

Solid dark bar: your hands-on work. Amber: the minimum wait. Hatched: the range sources disagree on, or an open-ended wait. (no source)

What we know so far. Nothing gates this path. 7 facts unknown, so the tier could be higher.
The tier is computed from these seven facts by a fixed rule, not chosen by the AI. Low: some facts are unknown or rest on forum reports. Verify before you plan around this.
Self-serve credentialsUnknownSources mention creating and configuring apps in the Developer Portal and generating a client secret, but do not explicitly detail whether credential generation is entirely self-serve.[1]
Limits until reviewedUnknownThe sources do not mention unreviewed app connection caps, token lifetimes, or developer mode restrictions. (no source)
Provider reviewUnknownApp review is mentioned for releasing apps in the marketplace, but the exact review requirements for standard external OAuth REST API integrations are not fully detailed in the snippets.[3]
Security assessmentUnknownNo security assessment requirements are mentioned in the provided text. (no source)
Business verificationUnknownDeveloper verification is mentioned in a submission checklist heading, but the details of business verification are not described.[3]
Mandatory feesUnknownAPI or listing fees are not mentioned in the sources. (no source)
Partner or paid accessUnknownThe sources do not state whether access to the REST APIs is gated by a waitlist or partner program. (no source)

You can start today without any of this. Composio already provides a managed OAuth app for Canva (canva, canva_mcp, canvas), so users can connect while you work through your own app. You need your own app for your brand on the consent screen, your own rate limits, or scopes beyond the defaults.

Steps

Agent steps an AI agent can do or draft for you. You steps that need your identity, accounts, legal authority or a real demo.

  1. Create and configure your app in the Developer Portal

    You

    Create and configure your app in the Developer Portal, including generating and saving a client secret and setting at least one authentication redirect URL.[1]

  2. Configure scopes in app settings

    You

    Enable and explicitly set the required scopes in your app's settings in the Developer Portal.[1][2]

  3. Implement the OAuth 2.0 flow with PKCE

    Agent

    Build the authorization flow using Authorization Code with PKCE (SHA-256), including generating a code_verifier, code_challenge, and handling redirect URIs and state parameters.[1]

What you will need

  • The authorization process requires OAuth 2.0 with the Authorization Code flow and Proof Key for Code Exchange (PKCE) using SHA-256.[1]
  • The code_verifier must be a high-entropy cryptographically random string between 43 and 128 characters long containing only ASCII letters, numbers, and -, ., _, or ~ characters.[1]
  • The scopes you request must already be set in your app's settings in the Developer Portal.[1]
  • When enabling and using scopes, you must be explicit (e.g., specifying asset:write does not grant asset:read permissions).[1][2]

Nuances that catch people out

  • If you have multiple redirect URLs set in your app's settings and the redirect_uri query parameter isn't supplied, the first redirect URL set is used by default.[1]
  • The state parameter must not be used to store the code_verifier value.[1]

Evidence

What we could not verify

  • Exact hands-on hours required for implementation
  • Calendar wait time for app approval
  • Whether self-serve credentials and developer mode limits apply
  • Specific business verification and security assessment prerequisites
