Hello, We have a workflow , which runs everyday morning at 5AM. This workflow has a filter criteria to filter the users who are mememers of a list ( who has list memembership) , once it read those users form the list , we have a custom code which creates a email body and calls : “hubspotClient.marketing.transactional.singleSendApi.sendEmail” API to send the emails to each user. As of now, the API call will go for each users once. After filers the custom code runs for each user everytime. We want to reduce the number of API calls. Is there any batch API or something in the workflow , which reads set of users for the first filter list and call the email in batch ? Thanks in advance. ---

Hello [@BérangèreL](https://community.hubspot.com/t5/user/viewprofilepage/user-id/230185) Thanks for the reply , I have gone through the page you have suggsted and that is not helpfull in pur case. As I told you we are calling API from worflow, the first filter is giving one data per user. The post suggest for batch API for task, what I’m looking for is batch API for transactional emails. ---

Hi @DBhavi I hope you are doing well. Currently, the HubSpot workflow does not allow for custom code actions to be performed on batches. However, it can be used to send transactional emails to individual users. I hope this will help you out. Please mark it as **Solution Accepted and upvote** to help another Community member. Thanks! ---
