Tools

• fillout_count_submissions ~338 tokens
  Count a form's submissions matching the same filters as fillout_list_submissions (date range, status, search) without pulling the answers — e.g. 'how many responses this week?' or 'how many partial submissions?'. Reads totalResponses from GET /forms/{formId}/submissions with limit=1.
• fillout_create_submissions ~1027 tokens
  Create up to 10 new submissions on a form, as if respondents had filled it in — e.g. to import responses collected elsewhere. Each submission needs its question answers (question ids from fillout_get_form); URL parameters, scheduling, payments, login email and timestamps are optional. Creates real r
• fillout_create_webhook ~199 tokens
  Subscribe a URL to a form's new submissions: Fillout will POST each submission (same shape as a fillout_list_submissions entry) to it. Returns the webhook id — keep it, it is the only handle for removing the webhook later. Fillout: POST /webhook/create.
• fillout_export_submissions ~423 tokens
  Fetch many submissions in one call by walking the offset pagination (150 per page, paced under Fillout's 5 requests/second limit), up to max_submissions. Same filters as fillout_list_submissions. Use this for analysis across a whole response set; the result says whether it was truncated. Fillout: GE
• fillout_get_form ~159 tokens
  Fetch one form's metadata: every question (id, name, type), calculations, URL parameters, scheduling and payment fields, and quiz settings. Use the question ids to read answers or to create submissions. Fillout: GET /forms/{formId}.
• fillout_get_submission ~185 tokens
  Fetch a single submission by id, with every answer. Fillout: GET /forms/{formId}/submissions/{submissionId}.
• fillout_list_forms ~84 tokens
  List every form in the Fillout account — each form's name and formId. Start here to find the formId the other tools need. Fillout: GET /forms.
• fillout_list_submissions ~478 tokens
  List one page of a form's submissions (answers to every question, calculations, URL parameters, scheduling, payments, quiz score, login email), filtered by date range, status or free-text search. Offset pagination: the response carries totalResponses and pageCount. Fillout: GET /forms/{formId}/submi
• fillout_remove_webhook ~151 tokens
  Stop a webhook from receiving submissions. Recoverable: create it again with fillout_create_webhook (it gets a new id). Fillout: POST /webhook/delete.
