RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
Desc	string	No	Function description.	description
Name	string	Yes	Function name.	demoFunction
SpaceId	string	Yes	Service space ID.	dece4ea0-d432-4cfa-8514-8a88d205e2b8
Memory	integer	No	Function memory size. Must be a multiple of 64 MB. Minimum is 128 MB. Maximum is 2048 MB.	256
Timeout	integer	No	Function timeout period in seconds. Default is 5. Valid range is 1 to 7200.	5
HttpTriggerPath	string	No	HTTP trigger path. To disable this feature, set this parameter to an empty string. The path must start with /http. It cannot end with /. Paths must be unique within the same service space. Only the following characters are allowed: /, -, `_`, `.`, letters, and digits. Maximum length is 128 characters.	/http/hello
TimingTriggerConfig	string	No	Scheduled trigger configuration. To disable this feature, set this parameter to an empty string. For configuration rules, see Use scheduled triggers for functions. Note Public preview: cron:0 0 /2 * . Commercial edition: 0 0 /2 * * *.	cron:0 0 * * * *
TimingTriggerUserPayload	string	No	Custom input parameter for scheduled tasks. Note This feature is supported only in the commercial edition.	hello
InstanceConcurrency	integer	No	Maximum concurrent invocations per instance. Default is 1. Valid range is 1 to 20. Setting a value greater than 1 reduces cold starts. Use this setting when your function spends most of its time waiting for downstream services. Do not use it if your function has shared state that cannot be accessed concurrently. Also avoid it if a single request consumes large amounts of CPU or memory. Note When you set this value to more than 1, memory must be at least 512 MB.	1
Runtime	string	No	Function runtime environment. Supported values include nodejs12 and nodejs14. For the full list, see Supported runtimes. Valid values: nodejs14 : nodejs14 nodejs12 : nodejs12 nodejs16 : nodejs16	nodejs14
