Download a Lucid invoice PDF

Automatically download a Lucid invoice PDF on lucid.app. Download one Lucid (Lucidchart/Lucidspark) billing invoice PDF, given the invoice number that lucid.app/list_invoices returns. Returns the real filename plus the PDF bytes as base64 (decode + write it yourself). Opens the invoices table, addresses the row by its own rowidentifier so a wrong number fails loudly instead of downloading the first row, and reads the bytes from payment.lucid.app rather than relying on the browser download (Lucid serves invoices inline, so the download never completes). Works whatever language the account is set to. Pass pdfUrl instead to skip the billing UI entirely.

Input

number optional

The invoice number as returned by lucid.app/list_invoices (e.g. 19888678). The invoices table is opened and the row with this number is downloaded. Required unless pdfUrl is given.

pdfUrl optional

A direct Lucid invoice PDF URL (https://payment.lucid.app/accounts/<accountId>/pdfInvoice/<number>), if you already have one. Skips opening the billing UI entirely.

Output

filename required

Filename from the file's Content-Disposition, falling back to Lucidchart-<number>.pdf. Lucid's own suggested name is the bare invoice number with no extension, so it is not used as-is.

pdf_base64 required

The PDF bytes, base64-encoded. Decode and write it yourself — the script is sandboxed and cannot write to disk.

number optional

The invoice number that was downloaded.

pdfUrl optional

The PDF URL the bytes were read from — reusable as this script's pdfUrl input to skip the UI next time.

size_bytes optional

Byte length of the decoded PDF.

You do not need one. "Download a Lucid invoice PDF" drives the real lucid.app pages in a browser, so it works whether or not lucid.app offers an API for this.
Optional: number, pdfUrl.
It returns number, pdfUrl, filename, pdf_base64, size_bytes.
Yes. It acts as you on lucid.app: on your own Chrome it reuses your session, and on a Reduck-hosted browser it loads the lucid.app cookies saved by the Reduck extension.
It only reads. It looks things up on lucid.app and changes nothing there.

List Lucid (Lucidchart) invoices

List Lucid (Lucidchart/Lucidspark) billing invoices, returning total plus each invoice's date, number, description and amount — metadata only. Feed a row's number to lucid.app/download_invoice to fetch that invoice's PDF. Works whatever language the account is set to. An account with no invoices returns an empty list, and a billing page that never finishes loading is reported as an error rather than passed off as an empty one.
