Credential configuration

To configure this credential, you need the Access Key ID and the Secret Access Key of the Programatic access user you want to use. Make sure this user has the required permissions to access Lambda to work properly. If you need to create the user, follow the instructions provided here.

In the extra options field, you can include any of the parameters found here.

Here is an example of a filled credential configuration form in YepCode:

JavaScript

Integration

New integration from credential

const awsLambdaClient = yepcode.integration.awsLambda("credential-slug");

New integration from plain authentication data

const { LambdaClient } = require("@aws-sdk/client-lambda");

const awsLambdaClient = new LambdaClient({
  credentials: {
    accessKeyId: "accessKeyId",
    secretAccessKey: "secretAccessKey",
  },
});

List Functions

List functions

const { ListFunctionsCommand } = require('@aws-sdk/client-lambda')
const listFunctionsCommand = new ListFunctionsCommand({});

const { Functions } = await awsLambdaClient.send(listFunctionsCommand);
for(const func of Functions) {
  console.log(func.FunctionName, func.Description)
}

Invoke Function

Invoke function

const { InvokeCommand, LogType } = require('@aws-sdk/client-lambda')

try {
    const params = {
    FunctionName: 'funcName',
    Payload: JSON.stringify({ foo: 'bar' }),
    LogType: LogType.Tail
  }
  const invokeCommand = new InvokeCommand(params)
  const { Payload, LogResult } = await awsLambdaClient.send(invokeCommand)
  const result = Buffer.from(Payload).toString()
  const logs = Buffer.from(LogResult, 'base64').toString()

  console.log(result)
  console.log(logs)
} catch (error) {
  throw error
} finally {
  // if you are using a custom http handler, you may call destroy() to close open connections.
  client.destroy()
}

Get Function

Get function

const { GetFunctionCommand } = require("@aws-sdk/client-lambda");
const getFunctionCommand = new GetFunctionCommand({ FunctionName: 'funcName' });
const response = await awsLambdaClient.send(getFunctionCommand)
console.log(response);

Python

Integration

New integration from credential

aws_lambda_client = yepcode.integration.aws_lambda("credential-slug")

New integration from plain authentication data

import boto3

session = boto3.Session(
    aws_access_key_id="accessKeyId",
    aws_secret_access_key="secretAccessKey",
    region_name="region"
)
aws_lambda_client = session.client("lambda")

List Functions

List functions

response = aws_lambda_client.list_functions()

for function in response['Functions']:
    print(function)

Invoke Function

Invoke function

import json

payload = {
    "foo": "bar"
}

response = aws_lambda_client.invoke(
    FunctionName='funcName',
    Payload=json.dumps(payload),
)
print(response['Payload'].read().decode('utf-8'))

Get Function

Get function

response = aws_lambda_client.get_function(
    FunctionName='funcName',
)

print(response)
