Getting started

Get your API Key

You can get an API Key from PrexView

Set up your API Key

If you can setup enviroment variables

export PXV_API_KEY="YOUR_API_KEY"

If you can't setup environment variables, create the PrexView object with your API Key as argument

pxv = PrexView('YOUR_API_KEY')

Include the library

PyPI installation

from prexview import PrexView

Sending an XML

To send an XML string use pxv.sendXML(xml, options) method, this method will return a Response object on success or thrown an error.

Example

pxv = PrexView();

options = dict(template='supported_languages', output='pdf')

xml = '''<?xml version="1.0" encoding="UTF-8"?>
<languages>
  <lang code="en">English</lang>
  <lang code="es">Español</lang>
  <lang code="fr">Française</lang>
</languages>'''

file = 'test.pdf'

try:
  res = pxv.sendXML(xml, options)

  with open(file, 'wb') as f:
    f.write(res['file'])
    f.close()

  print 'File created:', file
except Exception as e:
  print e

Sending a JSON

To send a JSON string or dictionary object use pxv.sendJSON(json, options) method, this method will return a Response object on success or thrown an error.

Example

pxv = PrexView();

options = {'template': 'supported_languages', 'output': 'pdf'}

json = {
  'languages': [
    {'code': 'en', 'name': 'English'},
    {'code': 'es', 'name': 'Español'},
    {'code': 'fr', 'name': 'Française'}
  ]
}

file = 'test.pdf'

try:
  res = pxv.sendJSON(json, options)

  with open(file, 'wb') as f:
    f.write(res['file'])
    f.close()

  print 'File created:', file
except Exception as e:
  print e

Response object

Property	Type	Description
id	string	Transaction ID.
file	binary	Document created by the service.
responseTime	int	Response time from service.
rateLimit	int	Maximum number of calls to the service.
rateLimitReset	int	Seconds to reset the rate limit.
rateRemaining	int	Number of remaining call to the service.

Options

Name	Type	Required	Description
template	string	Yes	Template's name to be used to document creation, you can use dynamic values.
output	string	Yes	Type of document that will be created by PrexView service, it must be html, pdf, png or jpg.
note	string	No	Custom information to be added to the document's metadata, it's limit up to 500 characters and you can use dynamic values.
format	string	No	Type of data used to the document creation, it must be xml or json, this should be inferred from library methods.
templateBackup	string	No	Template's name to use to be used if the option template is not available in the service.

Dynamic values

In template or note options you can use JSON sintax to access data and have dynamic values, for instance having the following JSON data:

{
  "Data": {
    "customer": "123"
  }
}

Your template or note can use any data attribute or text node, for instance:

'invoice-customer-{{Data.customer}}'

Then we will translate that to the following:

'invoice-customer-123'

And finally the service will try to find the template or note invoice-customer-123 in order to transform the data and generate the document.
