  Parameters:

  • issue (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• check_receipt_allocation read-only

  Checks how bank receipts are allocated to export invoices: arithmetic, duplicate allocations, missing row references, overallocated receipts and invoice balances. Takes anonymous row numbers and integer INR paise only; names, GSTINs and certificate numbers are not needed. Up to 200 invoices, 200 receipts and 1000 allocations.

  Parameters:

  • invoices (required) — array
  • receipts (required) — array
  • allocations (required) — array

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_statement3_requirements read-only

  Returns the fields of the Statement 3 JSON for a GST refund of accumulated ITC on exports without payment of tax (RFD-01), the file the GST portal otherwise requires from its Excel offline utility, and where each value comes from: export invoices and notes, bank BRC/FIRC rows, and shipping details for goods. Takes no input. Use it before validate_statement3 to learn which fields to collect.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• validate_statement3 read-only

  Checks records for the Statement 3 JSON for a GST refund of accumulated ITC on exports without payment of tax (RFD-01), the file the GST portal otherwise requires from its Excel offline utility. Applies the offline utility's own checks and returns every error and warning at once, with its row and field. Free; needs no sign-in; stores nothing. A file made by the official utility can be passed as data unchanged.

  Parameters:

  • data (required) — object — The document's fields, as its requirements tool lists them, or a JSON file from the official utility unchanged.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• generate_statement3 destructive

  Creates the Statement 3 JSON for a GST refund of accumulated ITC on exports without payment of tax (RFD-01), the file the GST portal otherwise requires from its Excel offline utility, from records that pass validate_statement3. Returns openUrl, a link the user opens in a browser to sign in by email, pay once per GSTIN and refund period, and download; the checked records are stored behind the link for 24 hours. With a connected account that has paid, it returns the file. The tool takes no GST portal password or OTP.

  Parameters:

  • data (required) — object — The document's fields, as its requirements tool lists them, or a JSON file from the official utility unchanged.
  • link — string — The openUrl from the other generate tool's result, so that one link holds both files.
  • direct — boolean — true to have the file returned to this client. It needs the user's Fast GST Refund account to be connected; if it is not, the client is asked to sign in. Leave out unless the user asked for the file here.

  Hints: read-only no · destructive yes · idempotent no · open-world no

• get_annexure_b_requirements read-only

  Returns the fields of the Annexure B JSON (statement of inward-supply invoices) for a GST refund of accumulated ITC (RFD-01), the file the GST portal otherwise requires from its Excel offline utility, and where each value comes from: purchase documents, tax amounts, the GSTR-2B period, reviewed ITC eligibility and the eight GSTR-3B reversal totals, with the fields each supply type leaves empty. Takes no input. Use it before validate_annexure_b to learn which fields to collect.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• validate_annexure_b read-only

  Checks records for the Annexure B JSON (statement of inward-supply invoices) for a GST refund of accumulated ITC (RFD-01), the file the GST portal otherwise requires from its Excel offline utility. Applies the offline utility's own checks and returns every error and warning at once, with its row and field. Free; needs no sign-in; stores nothing. A file made by the official utility can be passed as data unchanged. ITC eligibility, reversal amounts and GSTR-2B periods come from the taxpayer's reviewed records; the tool does not infer them.

  Parameters:

  • data (required) — object — The document's fields, as its requirements tool lists them, or a JSON file from the official utility unchanged.

  Hints: read-only yes · destructive no · idempotent yes · open-world no
