# Generate Invoice

### Input parameters

* TaskID

### How to call from app

HTTP request to: /generate-invoice/TASKID

### Logic (Plan)

1. Get all the user data for the assigned person and the task owner. 
2. ~~use the following api to generate a pdf:~~\
   [~~https://invoice-generator.com/developers#create-invoice-pdf~~](https://invoice-generator.com/developers#create-invoice-pdf)\
   ~~Example request:~~ [~~https://app.gitbook.com/o/Rxgn45SRgGRWbR4O7VXE/s/CfpEDb4ZyyJ4bmPlsblL/step-4-taskflow/generate-invoice~~](https://docs.tasksource.io/api-documentation/step-4-taskflow/generate-invoice)
3. Save the pdf file in the to the storage (Under: "invoices/TaskId")
4. Get the URL from the the storage and add it to the task document (InvoiceUrl="")

### Implemented Logic

1. get task, developer & owner data
2. add invoiceSend: true to the task data
3. create invoice with this details (using invoice-generator.com format so it will be easier if decided to use their service later)

   ```typescript
   const invoice = {
       from: `${developerData.firstName} ${developerData.lastName}
       \n${developerStreetAddress}${developerLocation} 
       ${developerPostalCode}`,
       to: `${ownerData.firstName} ${ownerData.lastName}`,
       currency: "eur",
       number: `${taskId}`,
       items: [
         {
           name: `Task #${taskId}`,
           quantity: 1,
           unit_cost: updatedTaskData.price,
         },
       ],
       fields: {
         tax: "%",
       },
       tax: 0,
       projectId: projectDoc.id,
       projectName: projectData.projectName,
       taskId: taskId,
       taskName: updatedTaskData.taskName,
       status: "open",
       updatedAt: updatedTaskData.updatedAt,
       developerEmail: updatedTaskData.assignToEmail,
       taskCreator: updatedTaskData.taskCreator,
     };
   ```
4. save invoice to "invoices/TaskId"
