1. Prereqs:

   • protobuf
   • go get github.com/twitchtv/twirp/protoc-gen-twirp_python
   • npm install protobufjs

2. Run extract_protos.js in inspector on invoice page

3. Then copy the new div to ./squareup.json

4. node ./node_modules/protobufjs/cli/bin/pbjs -t proto2 squareup.json > squareup.proto

5. Move the service definitions in squareup.proto to the bottom of the file; these aren't allowed inside messages

6. Add option allow_alias = true; inside the CatalogObjectType enum above DO_NOT_USE.

7. protoc --plugin=`which protoc-gen-twirp_python` --python_out=. --twirp_python_out=. -I. squareup.proto

8. Modify __service_name in squareup_pb2_twirp.py to include the full package names.

9. Change /twirp to /services

10. Change the headers= dict in _make_request to

    • Content-type: application/x-protobuf
    • Accept: application/x-protobuf

11. Now from python you can:

    req = _sym_db.GetSymbol("squareup.invoice.frontend.GetInvoiceRequest")()
    req.invoice_token = 'EzNe6oF5dAHLt9FsRAjbQg'
    client = InvoiceFrontendServiceClient('https://squareup.com')
    res =  client.get_invoice(req)
    print(res)
