Go: Append Logs to CloudWatch in Configured Pattern - rest

Question

I'm moving to Go from Java SpringBoot world...
go version: 1.18.3
I'm wring a AWS lambda using Go. It sits behind AWS api gateway as REST.
What it all does is adapt an incoming json payload into an external provider's REST API contract and sends out the request to it.
Now I want to log the following in AWS Cloudwatch,
incoming JSON payload
adapted JSON it sent out to the external API
response JSON it got back from the external API
response JSON set back
In SpringBoot Java we did this setting up Logback CloudWatch Appender configuration to add pattern to the logs.
Here's a sample pattern,
<appender name="AWS_CLOUDWATCH_LOGGER" class="com.abc.common.logback.CloudwatchAppender">
<encoder class="net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder">
<jsonFactoryDecorator class="com.abc.commonlogging.common.LogstashFactoryDecorator"/>
<providers>
<logstashMarkers/>
<pattern>
<pattern>
{"#timestamp":"%d{yyyy-MM-dd'T'HH:mm:ss.SSSZZ}",
"logger": "%logger",
"level": "%level",
"thread": "%thread",
"caller": "%caller",
"class": "%class",
"line_number":"#asLong{%line}",
"method": "%method",
"message": "%message",
"hostname":"${HOSTNAME}",
"transactionId":"%logcxt{t}"
</pattern>
</pattern>
<arguments>
<includeNonStructuredArguments>false</includeNonStructuredArguments>
</arguments>
</providers>
</encoder>
<!-- Log Group Name - be mindful of the name used here as it will create a new group if none is found-->
<logGroupName>BACKEND-SERVICE-LOGS</logGroupName>
<!-- vertical name - be mindful of the name used here as it will create a new stream if none is found-->
<logStreamName>${APPNAME}</logStreamName>
<!-- Set Flush Time -->
<!-- Required to make logging process asynchronous -->
<maxFlushTimeMillis>30000</maxFlushTimeMillis>
<!-- Hardcoded AWS region -->
<!-- So even when running inside an AWS instance in us-west-1, logs will go to ap-southeast-2 -->
<logRegion>ap-southeast-2</logRegion>
<!-- Maximum number of events in each batch (50 is the default) -->
<!-- will flush when the event queue has 50 elements, even if still in quiet time (see maxFlushTimeMillis) -->
<maxBatchLogEvents>50</maxBatchLogEvents>
</appender>
Here's how it's being setup for the log level,
<root level="INFO">
<appender-ref ref="CONSOLE" />
<appender-ref ref="FILE" />
<springProfile name="!LOCALHOST">
<appender-ref ref="AWS_CLOUDWATCH_LOGGER" />
</springProfile>
</root>
Here's how it's shown when logged into CloudWatch,
{
"#timestamp": "2022-08-05T01:47:27.491+0000",
"logger": "com.abc.logging.TRANSACTION_LOGS",
"level": "INFO",
"thread": "SimpleAsyncTaskExecutor-5",
"caller": "Caller+0\t at com.abc.service.logger.sifting.util.LogUtil.log(LogUtil.java:62)\nCaller+1\t at com.abc.service.logger.sifting.SiftingLoggingService.log(SiftingLoggingService.java:11)\nCaller+2\t at com.abc.service.logger.sifting.SiftingLoggingService.log(SiftingLoggingService.java:7)\nCaller+3\t at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)\nCaller+4\t at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)\n",
"class": "com.abc.service.logger.sifting.util.LogUtil",
"line_number": 62,
"method": "log",
"message": "Service Original Request: \n----------------------------\n{
"name": "Yomiko",
"address": {
"city": "Tokyo",
"street": "Shibaura St"
},

],
"isEmployed": false
}\n--------------------------------------",
"transactionId": "36654",
"HOSTNAME": "dataeng-apply-deployment-7d8f48cbcb-ddfhf"
}
How can I achieve this using Go?
Is there a straight forward way of doing it using Go?
Or can someone please suggest a library which would help achieving this?
