InvokeLambdaFunction

typed block

Invokes an AWS Lambda function with a collection of optional parameters. This AWS Lambda function is also given a copy of the flow run data if there is an associated contact with the flow.

Factories

`InvokeLambdaFunction`

InvokeLambdaFunction() -> InvokeLambdaFunctionHandle

Construct a fresh InvokeLambdaFunction block with an auto-generated id.

Use this when authoring from scratch, the runtime picks a UUID automatically.

`InvokeLambdaFunction`

InvokeLambdaFunction(id: String) -> InvokeLambdaFunctionHandle

Construct a InvokeLambdaFunction block with an operator-supplied id.

Parameter	Type	Required	Description
`id`	`String`	yes	Wire identifier, typically a Connect UUID restored by `decompile` so round-trips stay byte-stable.

Methods

`lambda_function_arn`

lambda_function_arn(value: String) -> InvokeLambdaFunctionHandle

Set the LambdaFunctionARN parameter. The ARN of the AWS Lambda function to be invoked. May be defined statically or dynamically. Measured 2026-10-14: Connect accepts any non-empty string here, an ARN, a JSONPath or neither, and a number; it refuses the empty string, a boolean, an object and an array.

Parameter	Type	Required	Description
`value`	`String`	yes	The ARN of the AWS Lambda function to be invoked. May be defined statically or dynamically. Measured 2026-10-14: Connect accepts any non-empty string here, an ARN, a JSONPath or neither, and a number; it refuses the empty string, a boolean, an object and an array.

`invocation_time_limit_seconds`

invocation_time_limit_seconds(value: i64) -> InvokeLambdaFunctionHandle

Set the InvocationTimeLimitSeconds parameter. The number of seconds to wait for a response from the AWS Lambda function. Measured 2026-10-14: Connect accepts a whole number from 1 to 8 as a JSON integer or a string ("05", "+5"), and refuses "9", "0", "5.5", 6.0, " 5" and every JSONPath.

Parameter	Type	Required	Description
`value`	`i64`	yes	The number of seconds to wait for a response from the AWS Lambda function. Measured 2026-10-14: Connect accepts a whole number from 1 to 8 as a JSON integer or a string (`"05"`, `"+5"`), and refuses `"9"`, `"0"`, `"5.5"`, `6.0`, `" 5"` and every JSONPath.

`invocation_type`

invocation_type(value?: InvocationType) -> InvokeLambdaFunctionHandle

Set the InvocationType parameter. Specifies the invocation type, allowed values: "SYNCHRONOUS" | "ASYNCHRONOUS".

Parameter	Type	Required	Description
`value`	`InvocationType`	no	Specifies the invocation type, allowed values: "SYNCHRONOUS" \| "ASYNCHRONOUS".

`lambda_invocation_attributes`

lambda_invocation_attributes(value?: Map<String, String>) -> InvokeLambdaFunctionHandle

Set the LambdaInvocationAttributes parameter. A map of additional data to send to the AWS Lambda function when invoking it. Keys and values may be set statically or dynamically.

Parameter	Type	Required	Description
`value`	`Map<String, String>`	no	A map of additional data to send to the AWS Lambda function when invoking it. Keys and values may be set statically or dynamically.

`response_validation`

response_validation(value?: Map (ResponseValidation)) -> InvokeLambdaFunctionHandle

Set the ResponseValidation parameter.

Parameter	Type	Required	Description
`value`	`Map (ResponseValidation)`	no

`next`

next(target: Handle) -> InvokeLambdaFunctionHandle

Wire the success-path transition. Substitutes the target's auto-generated UUID into the wire Transitions.NextAction slot.

Parameter	Type	Required	Description
`target`	`Handle`	yes	The block to route to once this block completes successfully.

`on_no_matching`

on_no_matching(target: Handle) -> InvokeLambdaFunctionHandle

Wire an error transition for NoMatchingError: if no other Error matches.

Parameter	Type	Required	Description
`target`	`Handle`	yes	Block to route to on `NoMatchingError`. if no other Error matches.

`meta_use_dynamic`

meta_use_dynamic(value?: bool) -> InvokeLambdaFunctionHandle

Set Metadata.ActionMetadata[<id>].useDynamic. Block-level summary toggle — true if any parameter on this block uses a dynamic JSONPath value.

Parameter	Type	Required	Description
`value`	`bool`	no	Block-level summary toggle — true if any parameter on this block uses a dynamic JSONPath value.

`set_id`

set_id(id: String) -> InvokeLambdaFunctionHandle

Override the auto-generated identifier with a specific wire id.

Parameter	Type	Required	Description
`id`	`String`	yes	Wire identifier override. Decompile threads this through to round-trip Connect-side UUIDs.

`meta_position`

meta_position(x: i64, y: i64) -> InvokeLambdaFunctionHandle

Set the block's canvas position. Mostly auto-emitted by decompile; authored scripts call Flow.auto_layout() instead and let the layout pass fill positions in.

Parameter	Type	Required	Description
`x`	`i64`	yes	Canvas X coordinate.
`y`	`i64`	yes	Canvas Y coordinate.

`set_meta`

set_meta(key: String, value: Dynamic) -> InvokeLambdaFunctionHandle

Single-key escape hatch, set one ActionMetadata key by name when the typed meta_* setters don't cover it.

Parameter	Type	Required	Description
`key`	`String`	yes	Wire key name (under `Metadata.ActionMetadata[<id>]`).
`value`	`Dynamic`	yes	Any JSON-serializable Rhai value.

`overwrite_meta`

overwrite_meta(value: Map) -> InvokeLambdaFunctionHandle

Full-replace escape hatch, overwrite the entire ActionMetadata blob.

Parameter	Type	Required	Description
`value`	`Map`	yes	Replacement map for the entire ActionMetadata sub-object.

`set_meta_param`

set_meta_param(param: String, flag: String, value: Dynamic) -> InvokeLambdaFunctionHandle

Set a single per-parameter ActionMetadata flag.

Parameter	Type	Required	Description
`param`	`String`	yes	Parameter name (e.g. `"Text"`).
`flag`	`String`	yes	Flag name (`"useDynamic"`, `"MFLAG_*"`, etc.).
`value`	`Dynamic`	yes	Flag value.

`overwrite_meta_param`

overwrite_meta_param(param: String, value: Map) -> InvokeLambdaFunctionHandle

Replace the entire flag map for one parameter.

Parameter	Type	Required	Description
`param`	`String`	yes	Parameter name.
`value`	`Map`	yes	Replacement flag map for the parameter.

`overwrite_parameters`

overwrite_parameters(value: Map) -> InvokeLambdaFunctionHandle

Wire-shape escape hatch, overwrite the entire Parameters blob.

Parameter	Type	Required	Description
`value`	`Map`	yes	Replacement parameter map for the block.

`raw_transitions`

raw_transitions(value: Map) -> InvokeLambdaFunctionHandle

Wire-shape escape hatch for non-canonical transition objects.

Parameter	Type	Required	Description
`value`	`Map`	yes	Replacement transitions map (raw JSON shape).
