The Functions service allows you to create custom behaviour that can be triggered by any supported Appwrite system events or by a predefined schedule.
Appwrite Cloud Functions lets you automatically run backend code in response to events triggered by Appwrite or by setting it to be executed in a predefined schedule. Your code is stored in a secure way on your Appwrite instance and is executed in an isolated environment.
You can learn more by following our Cloud Functions tutorial.

Create function
Create a new function. You can pass a list of permissions to allow different project users or team with access to execute the function using the client API.
required
Function ID. Choose a custom ID or generate a random ID with ID.unique()
. Valid chars are a-z, A-Z, 0-9, period, hyphen, and underscore. Can't start with a special char. Max length is 36 chars.
required
Function name. Max length: 128 chars.
required
Execution runtime.
An array of role strings with execution permissions. By default no user is granted with any execute permissions. learn more about roles. Maximum of 100 roles are allowed, each 64 characters long.
Events list. Maximum of 100 events are allowed.
Schedule CRON syntax.
Function maximum execution time in seconds.
Is function enabled? When set to 'disabled', users cannot access the function but Server SDKs with and API key can still access the function. No data is lost when this is toggled.
When disabled, executions will exclude logs and errors, and will be slightly faster.
Entrypoint File. This path is relative to the "providerRootDirectory".
Build Commands.
List of scopes allowed for API key auto-generated for every execution. Maximum of 100 scopes are allowed.
Appwrite Installation ID for VCS (Version Control System) deployment.
