  • click2mail_estimate_cost

  • click2mail_list_documents

    List the documents uploaded to the account (id, name, class, pages), most recent first. Use a document id when creating a job. GET /molpro/documents.

  • click2mail_list_projects

    List the mailing jobs of one project (id, status, description). This is how to see the account's jobs: pick a project from click2mail_list_projects. GET /molpro/projects/jobs.

  • click2mail_submit_job

  • click2mail_cancel_job

    WRITE: cancel a SUBMITTED job. The vendor documents this only for jobs paid by invoice and only before processing for mailing has started; otherwise it fails. The mailing is stopped for good, so get the user's explicit go-ahead first; `confirm` must be true. To remove a draft use
