Memberium v5 for Keap’s New API

Last updated: February 26, 2026

We’re giving you an early heads-up so you can stay ahead of upcoming changes.

Memberium v5 is currently in development to align with Keap’s move away from legacy XML-RPC APIs. This upgrade improves performance and long-term stability — but some legacy features will no longer be available.

How to prepare?

1. Audit your Actionsets:
   Start migrating actionsets into tag-triggered sequences. Any actionset-related feature in Memberium will no longer work in Memberium v5. For example, “Login Actionset” or “Run this Actionset:” in integrations such as LearnDash, LifterLMS and others. Same goes for any shortcodes that are supposed to run/trigger actionsets.
2. Move Passwords:
   Ensure you aren’t relying on the native Keap “Password” field under
   Memberium → Settings → Logins tab → “CRM Password Field”.
   Move that data to a custom field now (here’s how:
   https://keap.memberium.com/upgrading-default-password-field/). If you are already using a custom field as your “CRM Password Field”, you can skip this step.
3. Check Custom Code:
   If you have a developer who wrote custom SQL queries against Memberium tables, have them review the new v5 table structure. Any custom code or plugins performing direct database access, direct i2SDK calls, or direct usermeta access will break. Please have your developers review their code. Memberium database tables should never be accessed directly, since those can still change in the future. Instead, developers should either use our official PHP API functions (from /memberium2/includes/memberium_api.php) or manage their own data. The official Memberium PHP API functions (memberium_api.php) will remain stable and are the supported integration method.
4. Replace [memb_sync_contact]:
   Use the update contact HTTP POST instead of the [memb_sync_contact] shortcode. This moves your workflow away from manual syncing.

Shortcodes that will not be available in Memberium v5

• [memb_sync_contact]
• [memb_tag_date]
• [memb_client_login]
• [memb_actionset_button] – action_id parameter will no longer work, shortcode itself will still work
• [memb_action_link] – action_ids parameter will no longer work, shortcode itself will still work
• [memb_run_actionset]
• [memb_orderform]
• [memb_add_creditcard]
• [memb_filebox_link]
• [memb_filebox_url]
• [memb_list_filebox]
• [memb_upload_filebox]
• [memb_upload_message_filebox]

Workflow Updates

• Actionsets → migrate to tags + sequences
• Forced sync logic (for example [memb_sync_contact]) → switch to HTTP POST contact updates

For now, reviewing the items above will put you in a strong position.
