The Post to Chatter action doesn’t support Experience Cloud sites, and there are some limitations around what you put in the message.
Required Editions
| Available in: both Salesforce Classic (not available in all orgs) and Lightning Experience |
| Available in: Essentials, Professional, Enterprise, Performance, Unlimited, and Developer Editions |
Important Support and updates for Process Builder have ended as
of December 31, 2025. This means that support won't be provided for any process and bugs in
the Process Builder product won't be fixed. See Workflow Rules & Process Builder End of Support.
After December 31, 2025, existing processes continue to run, and you can activate, deactivate, and edit them; however, we recommend using Flow Builder. To migrate existing processes, plan your switch to Flow Builder and use the Migrate to Flow tool. For new automations, create flows in Flow Builder.
Unsupported Feeds
Processes can’t post to an Experience Cloud site user or group.
Chatter Message
- You can add up to 25 @mentions to a Chatter message.
- If you use Microsoft® Internet Explorer® version 11, you can’t paste text into a message. Copy and paste actions are allowed in all other supported browsers.
- Don’t start the message with a field reference, such as {![Account].Name}. Otherwise, the action fails to save. To work around this issue, add a space at the beginning of the message.
