Invoices

An invoice is the GST tax document raised against a sales order. These six endpoints let you list invoices, discover which orders are still awaiting invoicing, pull the invoice-ready data for an order, and post a completed invoice back to OptoSoft.

In an optical store the order and the invoice are usually separated in time: the order is taken (often with an advance), the lenses are fitted, and the invoice is raised on delivery. That is why get-invoice-data-by-salesorder exists — it hands you a pre-filled invoice built from the order, which you complete and post back.

Indian GST split. Whether tax lands as CGST + SGST (intra-state) or IGST (inter-state) is decided by the customer’s stateID against the branch state. Set the customer’s state correctly on customer upsert and OptoSoft computes the split for you.

Listing invoices

POST /api/Invoice/List Bearer token

Returns a paged, filtered list of invoices. This is the endpoint an accounting integration polls to pull sales into Tally, Zoho Books or a GST return workflow. Paging uses the fromPage / toPage row-range style.

Preparing a new invoice

GET /api/Invoice/get-customers-for-invoice Bearer token

Lists customers who currently have at least one order awaiting invoicing. Step one of the "raise an invoice" workflow — it narrows a large customer register down to just those with pending work.

Query parameters

None. Scope comes from the bearer token.

Example request

curl https://api.opto-soft.com/api/Invoice/get-customers-for-invoice \
  -H "Authorization: Bearer YOUR_TOKEN"

Example response — 200 OK

{
  "success": true,
  "data": [
    {
      "ID": "Q2ZQdGhSZVhBaVlXTnpaWFF3TWk0d01B",
      "CustomerName": "Rajesh Sharma"
    },
    {
      "ID": "Q2ZQdGhSZVhBaVlXTnpaWFF3T0M0d01B",
      "CustomerName": "Priya Patel"
    }
  ]
}

GET /api/Invoice/get-sales-orders-for-invoice Bearer token

For a chosen customer, lists their orders that are ready to be invoiced. Step two of the workflow.

Query parameters

Name	Type	Required	Description
customerId	string	Required	Encrypted customer ID from the previous call.

Example request

curl "https://api.opto-soft.com/api/Invoice/get-sales-orders-for-invoice?customerId=ENCRYPTED_CUSTOMER_ID" \
  -H "Authorization: Bearer YOUR_TOKEN"

Example response — 200 OK

{
  "success": true,
  "data": [
    {
      "SalesOrderID": "Q2ZQdGhSZVhBaVlXTnpaWFF3TWk0d01B",
      "SalesOrderNO": "SO-2024-0568"
    }
  ]
}

POST /api/Invoice/GetOrdersForNewInvoice Bearer token

Returns every order in the given company, branch and year that is still awaiting an invoice — the branch-wide view, rather than the per-customer view above. Use it to build a "pending invoicing" worklist.

Request body

Field	Type	Required	Description
companyID	int64	Required	Company (tenant).
branchID	int64	Required	Store.
yearID	int64	Required	Financial year.

Example request

curl -X POST https://api.opto-soft.com/api/Invoice/GetOrdersForNewInvoice \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "companyID": 18, "branchID": 24, "yearID": 9 }'

Example response — 200 OK

  "OrderList": [
    {
      "SalesOrderID": "Q2ZQdGhSZVhBaVlXTnpaWFF3TWk0d01B",
      "SalesOrderNO": "SO-2024-0568"

    }
  ]
}

GET /api/Invoice/get-invoice-data-by-salesorder Bearer token

The key endpoint of this module. Given a sales order, it returns a fully populated invoice draft — customer, line items, GST breakdown and totals — ready to be reviewed and posted back via save-invoice-data.

Query parameters

Name	Type	Required	Description
salesOrderId	string	Required	Encrypted sales order ID.

Example request

curl "https://api.opto-soft.com/api/Invoice/get-invoice-data-by-salesorder?salesOrderId=ENCRYPTED_SALES_ORDER_ID" \
  -H "Authorization: Bearer YOUR_TOKEN"

The response is an OMFastWizardModel — the same composite object used by Quick Sale. Round-trip it: take the returned object, adjust only what you need, and post it to save-invoice-data. Do not attempt to build one from scratch.

Saving an invoice

POST /api/Invoice/save-invoice-data Bearer token

Commits an invoice. The request body is the full composite OMFastWizardModel (94 top-level properties, most of them nested objects and UI display flags).

Top-level structure

Field	Type	Description
customerModel	object	The customer the invoice is raised against.
salesorderModel	object	The order being invoiced, with its line items.
receiptModel	object	Payment taken at the time of invoicing, if any.
eyeInfoModel	object	The prescription dispensed against this invoice.
eyecheckupRecallModel	object	Next eye-test recall to schedule for the customer.
purchaseOrderModel	object	Linked lab or supplier purchase order.
autoItemTypeSectionList	array	Item-type sections shown in the OptoSoft wizard.
sessionID	string	Cart session ID, when the invoice is built from a Quick Sale session.
orderDate	date-time	Order date.
expectedDate	date-time	Expected delivery date.
supplierID	string	Encrypted supplier ID for lab work.
fitterID	string	Encrypted fitter ID.
priorityID	string	Encrypted job-priority ID.
isLensAdded	boolean	Whether a lens line is present.
isSpectacleLensInOrder	boolean	Whether a spectacle lens is on the order.
isExternal	boolean	Marks an externally originated transaction.
userId	int64	Operator recording the invoice.
branchCity	string	Branch city, printed on the invoice.
visitorIP	string	Client IP recorded for audit.
showQuickSaleAdd…Section	boolean	Roughly 60 display flags controlling OptoSoft wizard sections (frames, sunglasses, lenses, contact lenses, accessories and so on). Preserve whatever the GET returned; they do not affect the saved invoice.

Always round-trip this model. Call get-invoice-data-by-salesorder first, modify only the fields you need to change, and post the whole object back. Constructing an OMFastWizardModel by hand is not supported and will produce incorrect tax totals.

Example flow

# 1. Pull the pre-filled invoice draft for the order
curl "https://api.opto-soft.com/api/Invoice/get-invoice-data-by-salesorder?salesOrderId=ENCRYPTED_SALES_ORDER_ID" \
  -H "Authorization: Bearer YOUR_TOKEN" -o draft.json

# 2. Adjust draft.json as needed (dates, payment, remarks)

# 3. Post it back to commit the invoice
curl -X POST https://api.opto-soft.com/api/Invoice/save-invoice-data \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  --data-binary @draft.json

Inspect the response body before treating the invoice as saved. A 200 here confirms the request was accepted, not necessarily that a document number was allocated.

Printing

Rendered invoice PDFs and print-ready HTML come from the catalog module — see Catalog & Master Data for /api/Common/invoice/pdf and /api/Common/invoice/pdf/html.
