PUT https://www.digicert.com/services/v2/util/validate-vmc-logo

Use this endpoint to check if the format of an SVG file is compatible with the requirements for Verified Mark Certificates (VMC) or a Common Mark Certificate (CMC).

Notice

This endpoint accepts raw SVG data. To submit compressed logo data formatted as a base64-encoded string, use the Validate VMC or CMC logo format (encoded) endpoint.

Request format

To submit a request to the Validate VMC or CMC logo format (SVG) endpoint:

  • Set the Content-Type header.

    • If the image data includes an XML tag (for example, <?xml version ="1.0" encoding ="UTF-8"?>), use image/svg+xml.

    • If the image data does not include an XML tag, use image/svg.

  • Submit the raw SVG data for the image as the payload of the request.

  • Omit the custom header X-DC-DEVKEY. This operation does not require authentication with an API key.

Response format

If the logo format meets VMC or CMC requirements, the endpoint returns a status of 204 No Content.

If there is a formatting issue with the logo, the endpoint returns an error message with a status of 400 Bad Request. The error message provides:

  • A brief description of the formatting issue.

  • The line and column number where you can find the problem when you open the file in a text editor.

To resolve issues with the SVG format of your logo:

  1. Open the SVG file in a text editor.

  2. Update the content at the locations displayed in the error messages.

  3. Save the file.

  4. Submit another request with your updated SVG data.
