Serverless Deploy to Different AWS Accounts

Question

I have serverless project with bunch of terraform resource creation. I would like to deploy Lambda functions in one AWS account and as part of serverless deploy, it can create API Gateway endpoints (pointing to lambda functions).

I would like to API Gateway to be created in Another AWS Account. Is it possible do purely in serverless. If not what are the options ?

Try an EventBridge approach. You should be able to access functions securely, without creating complex dual-account ARNs, Policy Scripts and permissions:

const AWS = require('aws-sdk');

function notifyMarketingTeam(email) {
 const eventBridge = new AWS.EventBridge({key:XXXXX,secret:XXXX region: 'us-east-1' }); 

 return eventBridge.putEvents({
   Entries: [
     {
       EventBusName: 'marketing',
       Source: 'acme.newsletter.campaign',
       DetailType: 'UserSignUp',
       Detail: `{ "E-Mail": "${email}" }`,
   },
   ]
 }).promise()
}
