How to merge multiple PDF Documents together in Python

Prepare yourself for the easiest tutorial you’ve ever read. With a little helping hand from an API, we will be setting up our PDF merging with virtually no effort whatsoever. Time to dive in.

We can install our client with pip install, like so:

pip install cloudmersive-convert-api-client

Following our installation, we will be able to call our PDF mergin function, shown below.

from __future__ import print_function
import time
import cloudmersive_convert_api_client
from cloudmersive_convert_api_client.rest import ApiException
from pprint import pprint
# Configure API key authorization: Apikey
configuration = cloudmersive_convert_api_client.Configuration()
configuration.api_key['Apikey'] = 'YOUR_API_KEY'
# Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
# configuration.api_key_prefix['Apikey'] = 'Bearer'
# create an instance of the API class
api_instance = cloudmersive_convert_api_client.MergeDocumentApi(cloudmersive_convert_api_client.ApiClient(configuration))
input_file1 = '/path/to/file' # file | First input file to perform the operation on.
input_file2 = '/path/to/file' # file | Second input file to perform the operation on.
input_file3 = '/path/to/file' # file | Third input file to perform the operation on. (optional)
input_file4 = '/path/to/file' # file | Fourth input file to perform the operation on. (optional)
input_file5 = '/path/to/file' # file | Fifth input file to perform the operation on. (optional)
input_file6 = '/path/to/file' # file | Sixth input file to perform the operation on. (optional)
input_file7 = '/path/to/file' # file | Seventh input file to perform the operation on. (optional)
input_file8 = '/path/to/file' # file | Eighth input file to perform the operation on. (optional)
input_file9 = '/path/to/file' # file | Ninth input file to perform the operation on. (optional)
input_file10 = '/path/to/file' # file | Tenth input file to perform the operation on. (optional)
try:
# Merge Multple PDF Files Together
api_response = api_instance.merge_document_pdf_multi(input_file1, input_file2, input_file3=input_file3, input_file4=input_file4, input_file5=input_file5, input_file6=input_file6, input_file7=input_file7, input_file8=input_file8, input_file9=input_file9, input_file10=input_file10)
pprint(api_response)
except ApiException as e:
print("Exception when calling MergeDocumentApi->merge_document_pdf_multi: %s\n" % e)

As you can see, you may merge up to ten files with one call, and the process may then be chained repeatedly on as many files as you like, with the order preserved.
