Cannot use Requests-Module on AWS Lambda

I believe you have lambda_function.py 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 lambda_function.py in project-dir, copy the content of lambda_function.py from lambda console and paste it in project-dir/lambda_function.py
• 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.

EDIT: On Oct-21-2019 Botocore removed the vendored version of requests: https://github.com/boto/botocore/pull/1829.

EDIT 2: (March 10, 2020): The deprecation date for the Lambda service to bundle the requests module in the AWS SDK is now January 30, 2021. https://aws.amazon.com/blogs/compute/upcoming-changes-to-the-python-sdk-in-aws-lambda/

EDIT 3: (Nov 22, 2022): AWS cancelled the deprecation so you can continue to use requests as described below. AWS Blog

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("https://httpbin.org/get", timeout=10)
   print(response.json())

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

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.

If you’re working with Python on AWS Lambda, and need to use requests, you better use urllib3, it is currently supported on AWS Lambda and you can import it directly, check the example on urllib3 site.

import urllib3

http = urllib3.PoolManager()
r = http.request('GET', 'http://httpbin.org/robots.txt')

r.data
# b'User-agent: *nDisallow: /denyn'
r.status
# 200

1. Copy whatever you have in the lambda_function fron AWS lambda console and paste it in a new python script and save it as lambda_function.py.

2. Make a new folder (I name it as package) and save requests module in it by running the following code in terminal: pip install -t package requests

3. Move lambda_function.py into the folder (package).

4. Go to the folder and select all content and zip them.

5. Go back to the AWS Lambda console. select the function and under the Function code section, click on ‘Action’ (on the right side) and select Upload a .zip file.

6. Upload the folder. lambda_function should be uploaded automatically.

7. Run and Enjoy.

lambda is looking for a specific folder structure and we are going to recreate in this manner in the steps below (https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html#configuration-layers-create):

1. make a folder on your desktop called "python," open a cmd terminal: cd desktop
2. pip install –target python requests
3. right click your python folder and zip it and rename the zip to ‘requests.zip’ – now if you look inside the zip you should see the python folder.
4. aws console > lambda > layers > create layer => name layer/upload requests.zip
5. aws console > functions > create function => in the "designer" box select layers and then "add layers." Choose custom layers and select
   your layer.
6. Go back to the function screen by clicking on the lambda symbol in the designer box. Now you can see "function code" again. Click lambda_function.py

Now you can import requests like this:

import json
import requests

def lambda_handler(event, context):
    # TODO implement
    response = requests.get('your_URL')
    return {
        'statusCode': 200,
        'body': json.dumps(response.json())
    }

Most of the comments somehow correct, but not enough informative for AWS beginners. Here is my long resume what needs to be done for accessing requests functionality:

1. Creates root folder for AWS Lambda function

% mkdir lambda-function

2. Go inside crated root folder

% cd lambda-function

3. Create entry point Python file for AWS Lambda.

% vi lambda_function.py

4. Paste a code into lambda_function.py

import requests
def lambda_handler(event, context):   
    response = requests.get("https://www.test.com/")
    print(response.text)
    return response.text 

5. Install requests library. Note:package folder created

% pip install --target ./package requests

6. Go inside package

% cd package

7. Zip package

zip -r ../deployment-package.zip .

8. Go into parent folder

% cd ..

9. Zip deployment packge and lambda function file

% zip -g deployment-package.zip lambda_function.py

1. In the AWS Lambda functions tap "Upload from" and pick ".zip file". Navigate to your zip package zip file: deployment-package.zip.
2. After upload all files will be inside AWS Lambda function.

Add a layer to your lambda function
by specifying this arn (ap-south-1)

 arn:aws:lambda:ap-south-1:770693421928:layer:Klayers-p38-requests-html:10
