# Update a group

Updates the details of an existing group.

This endpoint allows you to modify a group's branding, contact information, or business identity. Updates will apply to all future envelopes sent by accounts in the group and may affect the recipient-facing appearance of previously sent envelopes if branding settings are reused or cached.

To update the logo, supply a new base64-encoded image string. Contact and branding changes will take effect immediately.
