Download Facebook Page post and video data in CSV format, and import into Amazon Redshift tables.

Project Description

# Facebook to Redshift

This project connects to the Facebook Graph API (v2.7), downloads the latest data about posts and videos associated with a target Page, and formats and outputs the data as CSVs. It also (optionally) uploads the CSVs into an Amazon S3 bucket and imports the data into a corresponding table into Redshift using the copy command.

Many, many settings in this script must/can be customized to suit your needs.

## Requirements

  • Python3
  • Facebook account with admin access to target Facebook Page
  • (optional) Amazon S3 bucket and Redshift user with ability to create tables in a given schema (named facebook in the examples here)

## Installation and use

### 1. Clone this repo ### 2. Create a virtualenv and activate it.

If Python 3 is not your default Python version, you’ll need to tell virtualenv which version of Python to use.

virtualenv venv or virtualenv -p /path/to/python3 venv

. venv/bin/activate

### 3. Install requirements

pip install -r requirements.txt

  • If you don’t already have postgresql-devel installed, you’ll need to run yum install python-devel postgresql-devel first or else you’ll get an error like pg_config executable not found when pip tries to install psycopg2.

### 4. Create settings.py (using settings.py.example as a template).

#### a. Get a long-lived access token (fb_long_token)
  • Go to [Facebook’s Graph API Explorer](https://developers.facebook.com/tools/explorer) and make sure it is associated with your app (top right drop down).
  • Get your user access token, ensuring manage_pages and read_insights are both selected as permissions.
  • Add your user access token in as the value in the variable user_access_token in settings.py.
  • Add your app id and app secret in the client_id and client_secret variables in settings.py.
  • In your virtualenv, run python fb_get_token.py.
  • Add the output of the script to settings.py as your fb_long_token. This expires every 60 days.
  • To obtain a never-expiring access token for production after registering the app and associating it with the page: * Go to [Facebook’s Graph API Explorer](https://developers.facebook.com/tools/explorer) and make sure it is associated with your app (top right drop down). * Under Get Token, choose Get User Access Token, ensuring manage_pages and read_insights are both selected as permissions. * Under Get Token > Page Access Tokens, chose your target Page. * Click the little blue i to the left of the Token and note the expiration time. Choose Open in Access Token Tool. * Click the blue Extend Access Token button at the bottom of the page. The Access Token toward the top of the page should change. * Click the “Debug” button to the right. “Expires” should show “Never” * Paste this token into settings.py as the value for fb_long_token

#### b. Create or copy a parameter dictionary for each data CSV, using examples in settings.py. Add each dictionary to the list of data_types in settings.py.

  • If you run fb_to_redshift.py now with redshift_import set to False and without editing the parameter dictionaries, and your Page has post and video data, you should find three tidy CSVs (fb_posts.csv, fb_videos.csv and fb_video_viewer_demographics.csv) in the directory you specified in the files_dir variable – assuming you got the Facebook settings right.
  • There are six types of data downloads available, with corresponding template dictionaries in settings.py and retrieval functions in fb.py: * Basic post data (posts via get_posts_and_interactions) * Video insights for all Page videos OR for all Page videos in a video list (videos and video_list via get_video_stats) * Video viewer demographics for all Page videos OR for all Page videos in a video list (video_viewer_demographics and video_list_viewer_demographics via get_video_views_demographics) * Simple video view stats, collected at regular intervals to create a time series of video views (See fb_video_time_series.py and get_video_time_series)
  • If you want to use video_list or video_list_viewer_demographics to pull video data from only the videos in a particular Facebook Page list, you’ll need to get the list_ids. * To find the Facebook video list ids, visit [Graph API explorer](https://developers.facebook.com/tools/explorer/) and get a valid Page token. Next to GET -> /v2.8/ enter [page_id]?fields=video_lists and submit to get a list of all the Page video lists and IDs.
  • ['interval'] can be used in combination with post_limit to limit the amount of data retrieved by each API call. If you leave ['interval'] set to False the script will try to pull all available post or video data.
  • ['tablename'] is used only if redshift_import is set to True.
  • !IMPORTANT: data_types should include only the parameter dictionaries that correspond to CSVs that you want to generate (and maybe import). The script will loop through them to get the corresponding data.
#### c. (OPTIONAL) Set up Redshift import.
  • Set redshift_import to True, and this script will attempt to upload the generated CSVs to an S3 bucket and import the data into Redshift tables.

  • If you don’t already have one, [create a bucket in S3](http://docs.aws.amazon.com/gettingstarted/latest/swh/getting-started-create-bucket.html) and add its unique name to s3_bucket in settings.py.

  • [Create a Redshift database](http://docs.aws.amazon.com/redshift/latest/dg/t_creating_database.html), and get your [AWS IAM credentials](https://aws.amazon.com/iam/). Add database connection info and IAM credentials to settings.py.

  • Create tables in the schema facebook that correspond to the tablename and columns defined in your parameter dictionaries. The Redshift user whose credentials are in settings.py should own those tables and have the ability to add tables to that schema.Example table creation queries below match the example dictionaries:

    CREATE TABLE facebook.posts(post_id VARCHAR(256) PRIMARY KEY, message VARCHAR(max), created_time timestamp, likes INT, shares INT, comments INT, total_reach INT, link_clicks INT);

### 5. Run the script!

python fb_to_redshift.py

  • This script can take a long time to run, due to pagination, if the Page you’re pulling from has a lot of posts or videos.
  • You’ll get an error if you try to pull too much data at once. Edit post_limit and the [interval] parameter to reduce the amount of data you’re requesting per API call.
  • If you set test to True, your CSVs will have ‘_test’ appended to the filename. If you also set redshift_import to ‘true’, the script will append ‘_test’ to the tablenames - so you must create tables in advance of running the script in test mode for import to work. E.g. CREATE TABLE facebook.videos_test (LIKE facebook.videos).

### 6. Optional: Generate a time series of video views.

python fb_video_time_series.py

  • fb_to_redshift.py grabs the latest data for posts/videos created during the (optional) specified ['interval']. fb_video_time_series.py grabs a specific set of data for videos created after the time_series_start_date in settings.py. If you set redshift_import to True, fb_to_redshift.py will overwrite the latest data for existing videos already in the table, while fb_video_time_series.py appends a new row for the latest video at the time of data capture (snapshot_time). Thus with the time series option running at regular intervals (e.g. on a cron job) you can capture the way video views, reactions, etc. change over time.

  • fb_video_time_series.py uses the same settings.py file as fb_to_redshift.py, and it’s encapsulated in its own file so it’s easy to run it independently from the rest of the code.

  • Create the Redshift table before running the time series code:

    CREATE TABLE facebook.video_time_series(video_id VARCHAR(256), title VARCHAR(max), created_time timestamp, snapshot_time timestamp, total_views INT NULL, unique_viewers INT NULL, views_10sec INT NULL, reach BIGINT NULL, ms_viewed BIGINT NULL, likes INT NULL, comments INT NULL, reactions INT NULL, shares INT NULL, primary key (video_id, snapshot_time));

## FAQ

####1. How do I get different data from the Graph API?

  • Changing which fields are retrieved requires editing the parameter dictionaries and the corresponding functions in fb.py. If you’re importing data into Redshift as well, you’ll need to change the column names and data types to match. This is fussy work! Refer to the [Graph API reference](https://developers.facebook.com/docs/graph-api/reference) to guide you through which fields you need and use the [Graph API explorer](https://developers.facebook.com/tools/explorer/) to test and tweak your new URL and generate a sample API response.

####2. I want to rename/reorder the columns in the CSVs.

  • You can edit the column names in the [‘columns’] parameter in the appropriate parameter dictionary; but keep in mind that if you want to reorder the columns you’ll also have to change the order in the appropriate fb.py function. Changing column order will also break Redshift import unless you also rename the Redshift table columns.

## Ideas for potential contributions

  • Integration with the Facebook Marketing API for ads data.
  • Data import into other database types.
  • Other tools that facilitate download, formatting and import of data from Facebook.
