Cannot use Requests-Module on AWS Lambda

I need to do a rest-call within a python script, that runs once per day. I can't pack the "requests" package into my python-package using the AWS Lambdas. I get the error: "Unable to import module 'lambda_function': No module named lambda_function"

I broke it down to the hello_world predefined script. I can pack it into a zip and upload it. Everything works. As soon as I put "import requests" into the file, I get this error.

Here is what I already did:

  1. The permissions of the zip and the project folder (including subfolders) are set to `chmod 777`. So permissions shouldn't be a problem.
  2. The script itself is within the root folder. When you open the zip file, you directly see it.
  3. I installed the requests package into the root-folder of the project using `sudo pip install requests -t PATH_TO_ROOT_FOLDER`

The naming of everything looks like this:

  • zip-file:
  • py-file:
  • handler method: lambda_handler(event, context)
  • handler-definition in the "webconfig: lambda_function.lambda_handler

The file I want to run in the end looks like this:

import requests
import json

def lambda_handler(event, context):
    url = ''
    headers = {"content-type": "application/json", "Authorization": "Basic Zxxxxxxxxx3NjxxZxxxxzcw==" }
    response = requests.put(url, headers=headers, verify=False)
    return 'hello lambda_handler'

I'm glad for ANY kind of help. I already used multiple hours on this issue.


To use requests module, you can simply import requests from botocore.vendored. For example:

from botocore.vendored import requests

def lambda_handler(event, context):
   response = requests.get("")
   print response.json()

you can see this gist to know more modules that can be imported directly in AWS lambda

I finally solved the problem: The structure in my zip file was broken. It is important that the python script and the packed dependencies (as folders) are in the root of the zip file. This solved my problem.

It's a bit depressing if you find such easy errors after hours of try and failure.

I believe you have on the Lambda console. You need to first create the Lambda function deployment package, and then use the console to upload the package.

  • You create a directory, for example project-dir on your system (locally)
  • create in project-dir, copy the content of from lambda console and paste it in project-dir/
  • pip install requests -t /path/to/project-dir
  • Zip the content of the project-dir directory, which is your deployment package (Zip the directory content, not the directory)

Go to the Lambda console, select upload zip file in code entry type and upload your deployment package. Import requests should work without any error.

With this command download the folder package

pip install requests -t .

Run this command on your local machine, then zip your working directory, then upload to aws.
