Rest API Examples using Postman

Before you using EzzyBills, you will need to have an EzzyBills account. If you do not have one, go to www.ezzybills.com to sign up for a free trial. Then manually upload several files to EzzyBills – this way, you will have several invoices that you can retrieve.

Please try the following examples below in sequence.  Download Collection (zip file)

Example 4: How to generate Postman PDF Data

The easiest way to create the data to upload via postman is to use python. You can Install python on your computer then run the following script. The script will read your PDF then generate a raw.txt file (byte array representation of the PDF file), which can be uploaded to the postman collection.

import json
with open('test.pdf', 'rb') as img_file:
img_name = 'test.pdf'
data = img_file.read()
b = bytearray(data)
li = []
for i in b:
li.append(i)

raw_data = {"PictureName": "test.pdf", "PictureStream": li}
json_data = json.dumps(raw_data)

with open("raw.txt", 'w') as file_object:
file_object.write(json_data)

D:\python>python generatestream.py

This will generate a file which contains what you need to add to the postman collection.
