About this integration

Connect Finmei to Definable to auto-categorise transactions, draft invoices on closed deals, surface cash-flow signals. Personas call Finmei's 24 tools directly from chat or scheduled flows. Pair with a finance persona to keep books current and surface what needs human review.

Connect Finmei to Definable and it becomes a set of typed tools your agents plan with — triggered by events, run on schedules, or invoked mid-conversation. Every write is checked by the verifier before it lands.

24 tools available

The Finmei toolbox.

Every Finmei capability your agents can call, each with a typed schema the planner reads. The router picks the right tool per step; the verifier checks the result.

Create Expense

Tool to create a new expense with file upload (receipt or invoice). Use when you need to record an expense with supporting documentation. Requires multipart/form-data submission with file, date, total, currency, and seller information.

Create Invoice

Creates a new invoice in Finmei with buyer information and line items. Use this when you need to generate an invoice for a customer. You can specify: - Buyer details (person or company) - Products/services with quantities and prices - Invoice type (regular, VAT, preliminary, credit) - Currency, dates, and custom notes Example: "Create an invoice for Tech Solutions Inc with 3 months of support services at $99.99/month"

Delete Customer

Tool to delete a specific customer by their ID. Use after confirming the correct customer_id to remove the record.

Delete Invoice

Tool to delete an invoice. Use when you need to remove an existing invoice by its ID.

Delete Payment

Delete a payment record by its unique identifier. This action permanently removes the payment from the system. Returns success even if the payment doesn't exist (idempotent operation). Use this when you need to remove incorrect, duplicate, or obsolete payment records.

Delete Product

Deletes a product from the Finmei catalog by its unique identifier. This operation is idempotent - calling it multiple times with the same product_id will return success. The tool attempts multiple endpoint patterns to maximize compatibility across different Finmei API deployments. Use this when you need to: - Permanently remove a product from the catalog - Clean up discontinued or obsolete products - Remove test or duplicate product entries Note: If all API endpoints return 404, the action will succeed with a message explaining that the product doesn't exist or the API doesn't support deletion. This follows idempotent DELETE semantics.

Download Expense File

Tool to download the file associated with an expense. Returns the expense document file (PDF or image). Use when you need to retrieve the actual file content for an expense.

Download Invoice PDF

Tool to download an invoice as a PDF file. Use when you need to retrieve the PDF version of an invoice.

Update Expense File

Updates the file attachment of an existing expense in Finmei. Use this action when you need to attach or replace a receipt/invoice file for an expense. This endpoint is specifically for updating the file only - use the Update Expense action for updating other expense fields like amount, date, or description. The file is uploaded using multipart/form-data content type and typically should be a PDF or image file of the bill/receipt.

Update Invoice

Tool to update an existing invoice in Finmei. Use when you need to modify invoice details such as buyer information, products, dates, or currency.

Update Product

Updates an existing product in the Finmei product catalog. Use this action when you need to modify product details such as name, description, price, or currency. You must provide the product ID and at least one field to update. The action returns the complete updated product details. Prerequisites: - The product must already exist in the system (obtain product_id from List Products action) - At least one update field (name, description, price, or currency) must be provided Note: This action will fail if the product doesn't exist or if the Finmei API instance doesn't support product management endpoints.
