How do I add a tag to a contact?

Use the `add_tag_to_contact` tool and provide the contact ID and the tag ID. Your agent will associate the tag with that specific contact in ActiveCampaign.

What is the API rate limit for ActiveCampaign?

ActiveCampaign enforces a standard limit of 5 requests per second per account. Exceeding this returns a 429 error code.

Should I use API version 1 or 3?

While version 1 is still technically supported, we always recommend (and this agent defaults to) RESTful API version 3 for performance and stability.
