API Support: https://atendimento.zenvia.com/ Overview This is the reference documentation for the Zenvia REST-like API. The API exposes 18 endpoints secured with apiKey authentication.
Install Jentic One Beta
Connect the Zenvia APIs to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Zenvia APIs, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fzenvia.io%2Fzenvia" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fzenvia.io%2Fzenvia" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Use Cases
Patterns agents use Zenvia APIs for, with concrete tasks.
★ CRM Operations
Use the Zenvia APIs to perform crm operations programmatically. The API provides 18 endpoints covering core functionality including sendfacebookmessage, sendsmsmessage, sendwhatsappmessage.
Call POST /channels/facebook/messages to sendfacebookmessage
Automated SMS Management
Automate sms operations by combining multiple Zenvia APIs endpoints. Agents can sendsmsmessage and then sendwhatsappmessage in a single workflow.
Call POST /channels/sms/messages to sendsmsmessage, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Zenvia APIs endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle apiKey tokens manually.
Search Jentic for 'sendfacebookmessage', load the operation schema, and execute with Jentic-managed credentials

What agents get from Jentic-routed access to this vendor.
Setup
Wiring Zenvia APIs by hand means setting its TOKEN header on every request, coding separate handling for the Facebook, SMS, and WhatsApp channels on api.zenvia.com/v1, and wiring subscriptions yourself. Through Jentic you install once, import Zenvia from the API Directory, store the token once, and your agent calls it.
Permission scoping
Zenvia carries the message channel and content in the request body rather than as a target in the URL path, so limit the agent to the operations it needs, such as sending an SMS or a WhatsApp message. You leave out subscription deletion unless the agent is meant to manage webhooks.
Credential isolation
Your Zenvia token is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'send a WhatsApp message' or 'list webhook subscriptions', and Jentic returns the matching Zenvia operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Zenvia APIs through Jentic.
What authentication does the Zenvia APIs use?
The Zenvia APIs uses an API key passed in the `JWT` header. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.
Can I sendfacebookmessage with the Zenvia APIs?
Yes. Use the POST /channels/facebook/messages endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Zenvia APIs?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I sendfacebookmessage through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'sendfacebookmessage'. Jentic returns the matching Zenvia APIs operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Zenvia APIs have?
The Zenvia APIs exposes 18 endpoints covering sms, whatsapp, facebook operations.
Can I limit what my agent is allowed to do with the Zenvia APIs?
Yes. Because you run Jentic One yourself, your own rules decide which Zenvia operations and credentials the agent may use. Zenvia carries the message channel and content in the request body rather than in the URL path, so you can scope the agent to just the operations it needs, such as sending an SMS or a WhatsApp message, and leave out subscription deletion unless it is meant to manage webhooks. Your Zenvia token is injected at execution time and only for the calls you have allowed.
