Python wrapper library for building beautiful adaptive cards
Project description
Adaptive Cards
A thin Python wrapper for creating Adaptive Cards easily on code level. The deep integration of Python's typing package prevents you from creating invalid schemes and guides you while creating visual apealing cards.
If you are interested in the general concepts of adaptive cards and want to dig a bit deeper, have a look into the official documentation or start a jump start and get used to the schema.
💡 Please note
This library is still in progress and is lacking some features. However, missing fractions are planned to be added soon.
About
This library is intended to provide a clear and simple interface for creating adaptive cards with only a few lines of code in a more robust way. The heavy usage of Python's typing library should prevent one from creating invalid schemes and structures. Instead, creating cards and sending cards should be intuitive and work like a breeze.
For a comprehensive introduction into the main ideas and patterns of adaptive cards, have a look on the official documentation. I also recommend using the schema explorer page alongside the implementation, since the library's type system relies on these schemes.
💡 Please note
It's highly recommended to turn on the type check capabilities for Python in your editor. This will serve you with direct feedback about the structures you create. If you are trying to assign values of incompatible types, your editor will mark it as such and yell at you right in the moment you are about to do so.
Features
- Type annotated components based on Python's dataclasses
- Schema validation for version compatibility
- Simple
JSONexport - Compliant with the official structures and ideas
- Send cards to MS Teams via
TeamsClient
Dependencies
- Python 3.10+

Installation
pip install adaptive-cards-py
Library structure
Adaptive cards can consist of different kind of components. The four main categories beside the actual cards are Elements, Containers, Actions and Inputs. You can find all available components for each category within the corresponding file. The AdaptiveCard is defined in cards.py.
In addition to that, some fields of certain components are of custom types. These types are living inside the card_types.py file. For instance, if you are about to assign a color to a TextBlock, the field color will only accept a value of type Colors, which is implemented in the aforementioned Python file.
To perform validation on a fully initialized card, one can make use of the SchemaValidator class. Similar to the whole library, this class provides a simple interface with only on method. The validation currently checks whether all used fields are compliant with the overall card version
Usage
A simple card
A simple TextBlock lives in the elements module and can be used after it's import.
from adaptive_cards.elements import TextBlock
text_block: TextBlock = TextBlock(text="It's your first card")
For this component, text is the only required property. However, if more customization is needed, further available fields can be used.
from adaptive_cards.elements import TextBlock
import adaptive_cards.card_types as types
text_block: TextBlock = TextBlock(
text="It's your second card",
color=types.Colors.ACCENT,
size=types.FontSize.EXTRA_LARGE,
horizontal_alignment=types.HorizontalAlignment.CENTER,
)
An actual card with only this component can be created like this.
from adaptive_cards.card import AdaptiveCard
...
version: str = "1.4"
card: AdaptiveCard = AdaptiveCard.new() \
.version(version) \
.add_item(text_block) \
.create()
Find your final layout below.
💡 Please note
After building the object is done, the create(...) method must be called in order to create the final object. In this case, the object will be of type AdaptiveCard.
To directly export your result, make use of the
to_json() method provided by every card.
with open("path/to/out/file.json", "w+") as f:
f.write(card.to_json())
Adding multiple elements at once
Assuming you have a bunch of elements you want your card to enrich with. There is also a method for doing so. Let's re-use the example from before, but add another Image element here as well.
from adaptive_cards.elements import TextBlock, Image
import adaptive_cards.card_types as types
text_block: TextBlock = TextBlock(
text="It's your third card",
color=types.Colors.ACCENT,
size=types.FontSize.EXTRA_LARGE,
horizontal_alignment=types.HorizontalAlignment.CENTER,
)
image: Image = Image(url="https://adaptivecards.io/content/bf-logo.png")
version: str = "1.4"
card: AdaptiveCard = AdaptiveCard.new() \
.version(version) \
.add_items([text_block, image]) \
.create()
# Alternatively, you can also chain multiple add_item(...) functions:
# card = AdaptiveCard.new() \
# .version(version) \
# .add_item(text_block) \
# .add_item(image) \
# .create()
with open("path/to/out/file.json", "w+") as f:
f.write(card.to_json())
This will result in a card like shown below.
A more complex card

But we are still scratching the surface. You can do even better!
Validate schema
New components and fields are getting introduced every now and then. This means, if you are using an early version for a card and add fields, which are not compliant with it, you will have an invalid schema. To prevent you from exporting fields not yet supported by the card and target framework, a schema validation can be performed. It's as simple as that:
from adaptive_cards.validator import SchemaValidator, Result
...
version: str = "1.4"
card: AdaptiveCard = AdaptiveCard.new() \
.version(version) \
.add_items([text_block, image]) \
.create()
validator: SchemaValidator = SchemaValidator()
result: Result = validator.validate(card)
print(f"Validation was successful: {result == Result.SUCCESS}")
Send card to MS Teams
Of course, you want to create those cards for a reason. So once you did that, you might want to send it to one of the compatible services like MS Teams. See the following example, how this can be done, assuming that all previously mentioned steps are done prior to that:
...
from adaptive_cards.clients import TeamsClient
from requests import Response
...
# send card
webhook_url: str = "YOUR-URL"
client: TeamsClient = TeamsClient(webhook_url)
response: Response = client.send(card)
new_webhook_url: str = "YOUR-URL-OF-SECOND-CHANNEL"
client.set_webhook_url(new_webhook_url)
response: Response = client.send(card)
...
So far, there is only a MS Teams client available. If further services should be supported, give me some feedback by opening an Issue for instance.
Find further information about sending cards or creating Webhooks to/in MS Teams here.
