Brandfolder API

Brandfolder, part of Smartsheet, has a REST API that reads a company's approved assets with a user's API key. It has no guideline endpoint and no MCP server.

Last updated 2026-11-10

Brandfolder is a digital asset management (DAM) system, now documented by Smartsheet as Brandfolder by Smartsheet. Its REST API reads a company's assets and their attachments (the actual files), with approval status and availability dates, and sends webhooks when assets are created, updated or deleted. Requests use one Brandfolder user's API key and return what that user can see.

It suits internal tools and integrations that sync a company's approved files from Brandfolder into another system.

What does Brandfolder return?

  • LogosNo logo-specific type; logos are assets whose attachments carry the file URL, MIME type and dimensions.
  • ColoursAttachments can represent colours as well as files, but the reference documents no colour-value fields.
  • FontsSections can be set to hold fonts and attachments can be fonts, but the reference lists no font-specific fields.
  • GuidanceThe API reaches Brandguides only to list and create invitations; no endpoint returns guideline content.
  • FilesAssets hold attachments, the actual files, each with a file URL, MIME type, size and dimensions.

How is it billed?

Sold as plans (Premium, Enterprise) quoted per customer; no usage-based prices are published.

What are the limits?

No numeric rate limit is published; the API returns HTTP 429 when you send too many requests in a short period.

What do the terms require?

Using the API means agreeing to the API License Agreement; the link on brandfolder.com now redirects to Smartsheet's Developer Program Agreement.

Who keeps it current?

The customer's team, which manages assets in Brandfolder; Smart CDN links update automatically as creative is approved.

How do you call it?

GET https://brandfolder.com/api/v4/assets/<asset_key>/attachments?fields=cdn_url

When should you use something else?

  • For a product you offer to other companies, read Smartsheet's Developer Program Agreement first: an application may be offered to end users only after Smartsheet approves it in writing.
  • For guidelines, the API reaches Brandguides only to manage invitations, and no endpoint returns their content.
  • For agents, there is no official Brandfolder MCP server; the Smartsheet MCP server has no Brandfolder tools.
