Everything your agent can do with Mixmax and Tax ID Pro
Triggers and actions 1 trigger · 16 actions
- New message sent
Triggers when a Mixmax message (email) has been sent. Draft, scheduled and failed messages are skipped.
- Add contact
Creates a Mixmax contact, or updates your existing contact with the same email address.
- Add sequence recipient
Adds a recipient to a Mixmax sequence and starts sending the sequence to them, and returns whether they were added.
- Add unsubscribe
Adds one or more email addresses to your Mixmax unsubscribe list, or your workspace's list if you belong to one, so sequences stop sending to them.
- Find sequences by name
Returns the Mixmax sequences whose name matches the text you supply.
- Get message
Returns one Mixmax message by its ID, including its recipients, subject, tracking settings and send status. An error occurs if the message is not found.
- List calls
Returns calls placed with the Mixmax Dialer, newest first, optionally filtered to calls with or without recordings or widened to the whole workspace.
- List contacts
Returns the contacts you own in Mixmax, newest first, optionally filtered by a search on name, email, group or Salesforce account.
- List messages
Returns your Mixmax messages (drafts, scheduled, sent, or failed), newest first.
- List sequence recipients
Returns the recipients that were added to a Mixmax sequence, with each recipient's state and per-stage activity.
- List sequences
Returns the Mixmax sequences you can access, optionally filtered by name or folder.
- List tasks
Returns the Mixmax tasks (email, call, LinkedIn and to-do) visible to the connected user, optionally filtered and sorted.
- List templates
Returns the email templates you can access in Mixmax, optionally filtered by name, subject, folder or owner.
- Send message
Sends a saved Mixmax draft message, optionally updating its properties first. The message is queued and delivered shortly after.
- List formats
Returns every tax ID format Tax ID Pro supports, with its country, name, abbreviation and whether it applies to individuals, entities or VAT.
- Validate tax ID
Checks whether a tax ID number is valid for a given country and returns its compact and standard formats, the country name and the format name, or a message explaining why it is invalid.
- Validate tax IDs in batch
Checks a list of tax ID numbers from many countries in one run and returns a validity result for each, matched back by your own reference.
No trigger or action matches that. Ask your agent to add it: it reads the API documentation and builds what you describe.

Questions
Mixmax and Tax ID Pro, answered
What can start an automation from Mixmax?
Any of Mixmax's 1 trigger in the catalog, including New message sent. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Tax ID Pro when something happens in Mixmax?
Any of Tax ID Pro's 3 actions, including List formats, Validate tax ID and Validate tax IDs in batch. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Tax ID Pro to Mixmax?
Tax ID Pro has no triggers in the catalog today, so automations start in Mixmax. If you need the other direction, ask: your agent reads Tax ID Pro's API documentation and adds it.
Do I have to build a connector for Mixmax or Tax ID Pro?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Mixmax and Tax ID Pro without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
