# Sendgrid Twilio SendGrid Scheduled Sends API

The Twilio SendGrid Scheduled Sends API allows you to cancel or pause the send of one or more emails using a batch ID. A `batch_id` groups multiple scheduled mail send requests together with the same ID. You can cancel or pause all of the requests associated with a batch ID up to 10 minutes before the scheduled send time. See [**Canceling a Scheduled Send**](https://docs.sendgrid.com/for-developer. The API exposes 5 endpoints secured with bearer authentication.

## For AI agents

Programmatically cancel or pause a scheduled send, retrieve all scheduled sends. Covers 5 operations with bearer authentication.

## Scope

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

## Capabilities

- Cancel or pause a scheduled send
- Retrieve all scheduled sends
- Update a scheduled send
- Delete a cancellation or pause from a scheduled send
- Monitor Twilio SendGrid Scheduled Sends API operational status and events

## Use cases

### Productivity Operations

Use the Twilio SendGrid Scheduled Sends API to perform productivity operations programmatically. The API provides 5 endpoints covering core functionality including cancel or pause a scheduled send, retrieve all scheduled sends, retrieve scheduled send.

Example prompt: Call POST /v3/user/scheduled_sends to cancel or pause a scheduled send

### Automated Scheduled Sends Management

Automate scheduled sends operations by combining multiple Twilio SendGrid Scheduled Sends API endpoints. Agents can retrieve all scheduled sends and then retrieve scheduled send in a single workflow.

Example prompt: Call GET /v3/user/scheduled_sends to retrieve all scheduled sends, then verify the result

### AI Agent Integration via Jentic

AI agents discover and call Twilio SendGrid Scheduled Sends 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 'cancel or pause a scheduled send', load the operation schema, and execute with Jentic-managed credentials

## Why Jentic

- **Setup:** Wiring the Twilio SendGrid Scheduled Sends API by hand means setting up its bearer token auth, choosing the right US or EU host (api.sendgrid.com or api.eu.sendgrid.com), and handling status codes yourself. Through Jentic you install once, import the Scheduled Sends API from the API Directory, store the token once, and your agent calls it.
- **Permission scoping:** The Scheduled Sends API puts the batch id in the URL path (/v3/user/scheduled_sends/{batch_id}), so a rule can pin your agent to one scheduled batch. You choose the operations it may call, so a destructive one like deleting a scheduled send is not included unless you add it.
- **Credential handling:** Your Twilio SendGrid 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.
- **Discovery method:** Agents search Jentic by intent such as 'cancel or pause a scheduled send', and Jentic returns the matching Scheduled Sends operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

## FAQ

### What authentication does the Twilio SendGrid Scheduled Sends API use?

The Twilio SendGrid Scheduled Sends 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 cancel or pause a scheduled send with the Twilio SendGrid Scheduled Sends API?

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

### What are the rate limits for the Twilio SendGrid Scheduled Sends 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 cancel or pause a scheduled send through Jentic?

Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'cancel or pause a scheduled send'. Jentic returns the matching Twilio SendGrid Scheduled Sends API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.

### How many endpoints does the Twilio SendGrid Scheduled Sends API have?

The Twilio SendGrid Scheduled Sends API exposes 5 endpoints covering scheduled sends operations.

### Can I limit what my agent is allowed to do with the SendGrid Scheduled Sends API?

Yes. Because you self-host Jentic One, your own rules decide which operations the agent may call, so you can grant read-only access with GET /v3/user/scheduled_sends and withhold destructive calls like PATCH or DELETE /v3/user/scheduled_sends/{batch_id}. Since the batch_id sits in the URL path, a rule can pin the agent to a single scheduled batch rather than all of your scheduled sends. Your SendGrid bearer token is stored encrypted by your own instance and injected only at execution time, so the agent never sees the raw credential.
