Contentful provides a content infrastructure for digital teams to power content in websites, apps, and devices. Unlike a CMS, Contentful was built to integrate with the modern software stack. It offers a central hub for structured content, powerful management and delivery APIs, and a customizable web app that enable developers and content creators to ship digital products faster.
This SDK is intended to replace the former unofficial Python CDA SDK. The old SDK can still be found at: https://github.com/contentful-labs/contentful.py
Install Contentful from the Python Package Index:
sudo pip install contentful
Create a client:
import contentful
client = contentful.Client('cfexampleapi', 'b4c0n73n7fu1')
If you plan on using the Preview API you need to specify the api_url:
client = contentful.Client('cfexampleapi', 'b4c0n73n7fu1', api_url='preview.contentful.com')
You can query for entries, assets, etc. very similar as described in the Delivery API Documentation.
Please note, that all methods of the Python client library are snake_cased, instead of JavaScript's camelCase:
client.content_types()
client.entry('nyancat')
You can pass the usual filter options to the query:
client.entries({'content_type': 'cat'}) # query for a content-type by its ID (not name)
client.entries({'sys.id[ne]': 'nyancat'}) # query for all entries except 'nyancat'
client.entries({'include': 1}) # include one level of linked resources
client.entries({'content_type': 'cat', 'include': 1}) # you can also combine multiple parameters
The results are returned as contentful.resource.Resource <contentful.resource.Resource> objects. Multiple results will be returned as list:
content_type = client.content_type('cat')
content_type.description # "Meow."
System Properties behave the same and can be accessed via the #sys method:
content_type.id # => 'cat'
entry.type # => 'Entry'
asset.sys # { 'id': '...', 'type': '...' }
Entries can have multiple locales, by default, the client only fetches the entry with only its default locale. If you want to fetch a different locale you can do the following:
entries = client.entries({'locale': 'de-DE'})
Then all the fields will be fetched for the requested locale.
Contentful Delivery API also allows to fetch all locales, you can do so by doing:
entries = client.entries({'content_type': 'cat', 'locale': '*'})
# assuming the entry has a field called name
my_spanish_name = entries.first.fields('es-AR')['name']
When requesting multiple locales, the object accessor shortcuts only work for the default locale.
You can easily request a resource that is represented by a link by calling #resolve:
happycat = client.entry('happycat')
happycat.space
# <Link[Space] id='cfexampleapi'>
happycat.space.resolve(client)
# <Space[Contentful Example API] id='cfexampleapi'>
This works for any kind of Resource.
There is a helpful method to add image resize options for an asset image:
client.asset('happycat').url()
# => "//images.contentful.com/cfexampleapi/3MZPnjZTIskAIIkuuosCss/
# 382a48dfa2cb16c47aa2c72f7b23bf09/happycatw.jpg"
client.asset('happycat').url(w=300, h=200, fm='jpg', q=100)
# => "//images.contentful.com/cfexampleapi/3MZPnjZTIskAIIkuuosCss/
# 382a48dfa2cb16c47aa2c72f7b23bf09/happycatw.jpg?w=300&h=200&fm=jpg&q=100"
Entries can have fields in it's default locale accessible with accessor methods:
nyancat = client.entry('nyancat')
nyancat.name
# 'Nyan Cat'
This SDK provides a simple API to interact with resources that come from the API, by abstracting the underlying JSON structure of the objects, and exposing all the relevant fields as object properties.
For all resources, sys properties will be available as top level properties, for example:
space = client.space() space.id # will return the value of space.sys['id']
In the case of Entries and Assets, as well as having sys available as properties,
also all the fields on present on fields will be available as properties, for example:
entry = client.entry('nyancat')
entry.name
# 'Nyan Cat'
# this is equivalent to entry.fields()['name']
asset = client.assets()[0]
asset.file['details']['size']
# will return the size of the image
# this is equivalent to asset.fields()['file']['details']['size']
Other resources, which contain top level properties other than sys or fields,
have those available as object properties, for example:
locale = client.locales()[0] locale.default # True
space_id: Space ID of your target space.
access_token: API Access Token (Delivery by default, Preview if overriding api_url).
api_url: (optional) URL of the Contentful Target API, defaults to Delivery API (can be overriden for Preview API).
api_version: (optional) Target version of the Contentful API.
default_locale: (optional) Default Locale for your Space, defaults to 'en-US'.
environment: (optional) Default Environment for client, defaults to 'master'.
https: (optional) Boolean determining wether to use https or http, defaults to True.
authorization_as_header: (optional) Boolean determining wether to send access_token through a header or via GET params, defaults to True.
raw_mode: (optional) Boolean determining wether to process the response or return it raw after each API call, defaults to True.
gzip_encoded: (optional) Boolean determining wether to accept gzip encoded results, defaults to True.
raise_errors: (optional) Boolean determining wether to raise an exception on requests that aren't successful, defaults to True.
content_type_cache: (optional) Boolean determining wether to store a Cache of the Content Types in order to properly coerce Entry fields, defaults to True.
reuse_entries: (optional) Boolean, when True, reuse hydrated Entry and Asset objects within the same request when possible. Can result in a large speed increase and better handles cyclical object graphs. This can be a good alternative to max_include_resolution_depth if your content model contains (or can contain) circular references.
proxy_host: (optional) URL for Proxy, defaults to None.
proxy_port: (optional) Port for Proxy, defaults to None.
proxy_username: (optional) Username for Proxy, defaults to None.
proxy_password: (optional) Password for Proxy, defaults to None.
max_rate_limit_retries: (optional) Maximum amount of retries after RateLimitError, defaults to 1.
max_rate_limit_wait: (optional) Timeout (in seconds) for waiting for retry after RateLimitError, defaults to 60.
max_include_resolution_depth: (optional) Maximum include resolution level for Resources, defaults to 20 (max include level * 2). Note that when reuse_entries is enabled, the max include resolution depth only affects deep chains of unique objects (ie, not simple circular references).
application_name: (optional) User application name, defaults to None.
application_version: (optional) User application version, defaults to None.
integration_name: (optional) Integration name, defaults to None.
integration_version: (optional) Integration version, defaults to None.
The client also includes a wrapper for the synchronization endpoint.
You can call it either with initial=True or with a previous sync_token,
additional options are described in the API Documentation:
sync = client.sync({'initial': True}) # Returns all content currently in space
# <SyncPage next_sync_token='w5ZGw6JFwqZmVcKsE8Kow4grw45QdybCnV_Cg8OASMKpwo1UY8K8bsKFwqJrw7DDhcKnM2RDOVbDt1E-wo7CnDjChMKKGsK1wrzCrBzCqMOpZAwOOcOvCcOAwqHDv0XCiMKaOcOxZA8BJUzDr8K-wo1lNx7DnHE'>
