Get invoice draft link
well_get_invoice_draft_linkGet the link to the web page that shows one draft invoice, read only, to whoever holds it: the sheet as it stands, what the draft still lacks before it can be issued, and one button back to WhatsApp. The first call for a draft makes the link; every later call returns the same address, and call_to_action updates its button. The link stops when the draft is issued or deleted. It changes nothing on the invoice. Only a workspace owner or admin can get the link.
REQUIRED: invoice_id (an open draft of this workspace). OPTIONAL: call_to_action ("back_to_whatsapp", "send_on_whatsapp" or "none").
Returns url, or refusal_reason: "not_found" (no such invoice here), "not_an_open_draft" (the invoice is issued, paid or canceled) or "unavailable" (this deployment has no web app address) or "admin_only" (the caller is not a workspace owner or admin; say so and give no link).
When the token authorizes one workspace, call this directly — no workspace call is needed first. When it authorizes several, this read will not guess which one you mean: pass workspace_id on the call.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| invoice_id | Yes | The draft invoice the link opens. | |
| workspace_id | No | Target workspace. Omit when the token authorizes one workspace. Required when it authorizes several: this read reports one workspace's own figures and will not choose which. | |
| call_to_action | No | The one button the page shows under the draft: "back_to_whatsapp" returns to this chat, "send_on_whatsapp" opens it with a message asking Well to issue this draft, "none" shows no button. Omitted, a link handed out before keeps its button and a new one shows none. | |
| conversation_id | No | The conversation id returned by the previous Well result, in its meta under well/conversation_id, in its structuredContent, or in its JSON text block. Pass it back on every call in the same conversation, including a call a card makes, so the chosen workspace and the earlier answers still apply. It decides the conversation on its own: nothing the host states about the session replaces it. Omit it only on the first call of a conversation. | |
| workspace_scope | No | Restrict this call to the family: the token's primary workspace plus the company workspaces under it that you are a member of. Unrelated authorized workspaces drop out of the read; row reads merge across the family, while a per-workspace figure still reports exactly one workspace. |
Output Schema
| Name | Required | Description | Default |
|---|---|---|---|
| url | Yes | The page address that opens the draft, read only. The same address on every call for the same draft. | |
| error | No | ||
| success | Yes | ||
| invoice_id | No | ||
| refusal_reason | No | ||
| conversation_id | No | The conversation this result belongs to. Pass it back as the conversation_id argument on every later Well call in the same conversation. | |
| newly_connected | No | Tools that connected to this workspace since the last result and that no session was told about yet, oldest first. Present only when at least one tool is new. The connected-line rule says when to tell an entry; when it does, one line per entry, in the person's language: "<name> is connected.". Never fold several entries into one sentence. Each entry comes back once, on one result only: never repeat its line later. | |
| resolved_workspace | No | The workspace that answered, when the caller named none and the token authorizes several. | |
| conversation_id_note | No | Present only when the server opened a fresh lane, stating that no choice recorded earlier was read. | |
| conversation_id_source | No | Where the conversation id came from: the host's own request meta, the caller's argument, or a fresh lane the server opened. |
