Connect one Webflow site with a site API token. Choose its scopes in the site settings, then add the token to Agent Serve.
Prerequisites
Only site administrators can generate site tokens. Each site allows a maximum of 5 tokens — if you're at the cap, revoke an unused one before creating a token for Agent Serve.
Setting Up the Site Token
Open your site's Site settings and go to Apps & integrations → API access
Click Generate API token and give it a recognizable name (e.g. agentserve-workflows)
Select the scopes the token needs. The minimum set for Agent Serve's Webflow blocks is:
Sites: Read-only
CMS: Read and writeThe picker offers no access, read-only, or read and write per category. Sites: Read-only (sites:read) is required for Agent Serve to verify the token when you connect it. CMS: Read and write (cms:read + cms:write) covers Agent Serve's Webflow tools — listing, getting, creating, updating, and deleting CMS items. Add other scopes only if you need them
Copy the token when it's shown. Webflow only displays it once — if you close the dialog, you'll have to generate a new token.
Site tokens expire after 365 consecutive days of inactivity. Any API call resets the clock, so a workflow that runs regularly keeps its token alive indefinitely — but a workflow that sits dormant for a year will start failing silently with authentication errors. If a workflow runs rarely, set a calendar reminder to run it (or any Webflow block) at least once a year, or check the credential periodically in Agent Serve.
Adding the Site Token to Agent Serve
Open Integrations from your workspace sidebar
Search for "Webflow" and open it, then click Add to Agent Serve and choose Add site token
Paste the site API token and optionally set a display name and description
Click Add site token. Agent Serve verifies the token by listing the sites it can access — if it fails, you'll see a specific error explaining what went wrong. A token created without the sites:read scope fails this check even if its CMS scopes are correct.
The token is encrypted before being stored, along with the site it grants access to.
Using the Credential in Workflows
Add a Webflow block to your workflow. In the credential dropdown, select the saved Webflow site token. Select it and configure the block as you normally would.
The block calls Webflow's Data API (api.webflow.com/v2/...) using the token. It can only reach collections and items belonging to the token's site — pointing a block at a different site's collection fails with an access error.
