### **API Validations**

1. The file in the request should be a PDF file.
2. Size limit of the file should be less than 1MB.&#x20;

### **API Constraints**

1. This API needs to be authenticated with a valid user authentication token. If the authentication token is not present or is invalid, the API will return HTTP Status Code 401.
2. If the authentication token is valid, but the user does not have the authorization to download invoice with given search parameters, then the API will return an error "You don't have any data present for the selected Document Details".
3. You should first enable DSC setting on Clear E-Invoice Portal. Also only admin or super admin user can sign DSC.
4. X,Y Signature coordinates depend on the resolution of the PDF. If signature exceeds the actual page size, signature won’t be visible on the output PDF.
5. For landscape pdf we can use x and y as <=500 ,anything above 500 will be set to default value.&#x20;
