How do I create an invoice in Wave from a workflow?
Short answer: You can create invoice in Wave by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Wave Create Invoice action to a workflow, map its 2 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.
Inputs
The fields this action accepts.
Every field can be mapped from an upstream trigger, AI step, table row, or hard-coded literal.
| Field | Type | Required | Description |
|---|---|---|---|
Customer ID customer_id | string | Required | The Customer ID assigned by Wave. Find via the corresponding list/search operation in this app. Use the exact ID, not a name or label. |
Items (JSON array) items_json | string | Required | [{"productId":"prod_abc","unitPrice":"100","quantity":2}] |
Sample request
{"customer_id": "{{trigger.customer_id}}","items_json": "{{trigger.items_json}}"}
Returns
{"data": {"invoiceCreate": {"invoice": {"id": "inv_abc","status": "DRAFT","invoiceNumber": "1"},"didSucceed": true}}}
Use these fields in downstream nodes for routing, logging, or error handling.

FAQ
Questions about Create Invoice.
What does the Create Invoice action do in Wave?
Creates an invoice in Wave via the GraphQL invoiceCreate mutation, with customer, line items, taxes, and due date. Used to invoice on milestone completion or to mirror billable activity from another system.
What inputs does Create Invoice require?
Required: Customer ID, Items (JSON array). Every input accepts a static value or a variable from any upstream node in your workflow.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if Wave returns an error?
The run history shows the failed step with its input and the error message Wave returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.
Does Create Invoice support batch operations?
Run Create Invoice inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Wave's rate limits.
