# Sendgrid Twilio SendGrid Email Activity API

The Twilio SendGrid Email Activity API allows you to query all of your stored messages, query individual messages, and download a CSV with data about the stored messages. Once retrieved, you can inspect the data associated with your messages to better understand your mail send. For example, you may retrieve all bounced messages or all messages with the same subject line and search for commonalitie. The API exposes 4 endpoints secured with bearer authentication.

## For AI agents

Programmatically filter all messages, filter messages by message id. Covers 4 operations with bearer authentication.

## Scope

Does not handle payments, crm, or developer tools - use for communications only.

## Capabilities

- Filter all messages
- Request CSV
- Download CSV
- Query and filter Twilio SendGrid Email Activity API records by parameters
- Monitor Twilio SendGrid Email Activity API operational status and events

## Use cases

### Communications Operations

Use the Twilio SendGrid Email Activity API to perform communications operations programmatically. The API provides 4 endpoints covering core functionality including filter all messages, filter messages by message id, request csv.

Example prompt: Call GET /v3/messages to filter all messages

### Automated Email Activity Management

Example prompt: Call GET /v3/messages/{msg_id} to filter messages by message id, then verify the result

### AI Agent Integration via Jentic

AI agents discover and call Twilio SendGrid Email Activity API 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 bearer tokens manually.

Example prompt: Search Jentic for 'filter all messages', load the operation schema, and execute with Jentic-managed credentials

## Key endpoints

## Why Jentic

- **Setup:** Wiring the Twilio SendGrid Email Activity API by hand means learning its bearer auth where the API key is the token, calling api.sendgrid.com, and polling message download jobs yourself. Through Jentic you install once, import the Twilio SendGrid Email Activity API from the API Directory, store the key once, and your agent calls it.
- **Permission scoping:** This API is read-and-export oriented, with the message id in the URL path (/v3/messages/{msg_id}), so a rule can pin your agent to reading one message and its downloads. You choose the operations it may call, so anything you do not add stays out of reach.
- **Credential handling:** Your Twilio SendGrid Email Activity API key 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.
- **Discovery method:** Agents search Jentic by intent such as 'filter all messages' or 'download message activity', and Jentic returns the matching Twilio SendGrid Email Activity API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

## FAQ

### What authentication does the Twilio SendGrid Email Activity API use?

The Twilio SendGrid Email Activity API uses a Bearer token in the Authorization 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 filter all messages with the Twilio SendGrid Email Activity API?

Yes. Use the GET /v3/messages endpoint. The API returns structured JSON responses that agents can parse and act on directly.

### What are the rate limits for the Twilio SendGrid Email Activity API?

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 filter all messages through Jentic?

Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'filter all messages'. Jentic returns the matching Twilio SendGrid Email Activity API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.

### How many endpoints does the Twilio SendGrid Email Activity API have?

The Twilio SendGrid Email Activity API exposes 4 endpoints covering email activity operations.

### Can I limit what my agent is allowed to do with the Twilio SendGrid Email Activity API?

Yes. Jentic One is self-hosted, so you set the rules that decide which operations and credentials your agent may use. Because this API is read-and-export oriented, you can allow only the calls you want, such as filtering messages with GET /v3/messages or reading a single message with GET /v3/messages/{msg_id}, while withholding the CSV request and download operations. Since the message ID sits in the URL path, a rule can pin the agent to one message and its downloads, and any operation you do not add stays out of reach.
