Everything your agent can do with Unisender and ViaCep
Triggers and actions 1 trigger · 4 actions
- New Subscriber
Fires when a contact subscribes to a Unisender list (optionally one chosen list). Registers and removes its Unisender webhook automatically.
- Get Contact
Fetches a contact by email address, including its status, additional fields and the lists it belongs to with its subscription status in each. An error occurs if the contact is not found.
- Unsubscribe Contact
Marks a contact's email as unsubscribed from one or more lists (or from all lists when none are given).
- Find CEPs by logradouro
Search for postal codes (CEPs) matching a given state, city, and street name.
- Get address by CEP
Look up a Brazilian address (street, neighborhood, city, state, IBGE code, DDD) by an 8-digit postal code (CEP).
No trigger or action matches that. Ask your agent to add it: it reads the API documentation and builds what you describe.
Each app on its own
