Download a Slack invoice PDF
Input
billId optionalA bill ID from slack.com/list_invoices, used only when pdfUrl is not given. Combined with workspaceDomain to build the URL.
pdfUrl optionalThe statement's download URL as returned by slack.com/list_invoices (https://<workspace>.slack.com/admin/billing/<billId>/pdf). Preferred over billId.
workspaceDomain optionalWorkspace host to target when using billId, e.g. acme.slack.com. Defaults to my.slack.com (primary workspace). Ignored when pdfUrl is given.
Output
filename requiredThe real suggested filename, taken from the file's Content-Disposition (e.g. Slack-Statement-SBIE-10873175.pdf). Falls back to Slack-<billId>.<ext> if Slack sends no Content-Disposition.
pdf_base64 requiredThe file bytes, base64-encoded. Decode and write it yourself — the script is sandboxed and cannot write to disk.
size_bytes optionalByte length of the decoded file.
content_type optionalThe file's own MIME type. Normally application/pdf; Slack answers application/zip for a bundled statement, in which case pdf_base64 holds zip bytes and filename ends in .zip.
List Slack invoices
List Slack billing statements from the workspace's admin billing history. Returns workspace, total and invoices (date, statement, billId, amount, status, description, pdfUrl) — metadata only. Feed a row's pdfUrl (or billId) to slack.com/download_invoice to fetch that statement's PDF. Requires a workspace billing admin; defaults to the primary workspace, or pass workspaceDomain (e.g. acme.slack.com).
Slack login (Google SSO)
Log into a Slack workspace using Sign in with Google, then open that workspace. Handles Google's account chooser and consent along the way. Pass the workspace subdomain (e.g. "myteam" for myteam.slack.com) and optionally which Google account to use; your Google account must already have access to the workspace.
Set Slack channel topic
Set a channel's topic (the short line shown in the header) by name or id. Topics are limited to 250 characters, and a longer one is refused up front rather than part-way through. Pass an empty string to clear the topic. Returns the applied topic. Requires login.
