Hi @jhpark,
I don’t think there is API providing the last login time of a cloud user. Since you also asked this in Cloud User last login time or User last active... add on about, I assume you are developing a Jira Cloud app so you should make sure you are familiar with the following documentation relevant to user data:
- Jira REST API
- [Cloud Admin User Management REST API] (About cloud admin REST APIs)
- Jira Cloud Webhooks (there are 3 user webhooks)
- User privacy guide for app developers
