  • Users with a role of Owner always have access to all resources within the organization.

  • The change permissions endpoint accepts a JSON object labeled change with three parameters.

  • The first parameter is type, which indicates which object you want to change the membership permissions of. Valid type values are project_members, form_members, and layer_members.

  • The second parameter is the id of the object you want to change the permission of. Valid ID keys are project_id, form_id and layer_id. Values must be valid resource IDs.

  • The third parameter is the changeset you would like to add or remove. This is a key of either add or remove with the value an array of valid member IDs that you would like to alter.

  • Permissions provided from Groups take priority over normal permissions. If you attempt to remove a member's Group-provided access to a form, project, or layer, the request will fail with a 422 status code response and the member's permissions will not change
