# Sendgrid Twilio SendGrid Templates API

The Twilio SendGrid Templates API allows you to create and manage email templates to be delivered with SendGrid's sending APIs. The templates you create will be available using a template ID that is passed to our sending APIs as part of the request. Each template may then have multiple versions associated with it. Whichever version is set as "active" at the time of the request will be sent to your. The API exposes 11 endpoints secured with bearer authentication.

## For AI agents

Programmatically create a transactional template., retrieve paged transactional templates.. Covers 11 operations with bearer authentication.

## Scope

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

## Capabilities

- Create a transactional template.
- Retrieve paged transactional templates.
- Duplicate a transactional template.
- Edit a transactional template.
- Delete a template.

## Use cases

### Communications Operations

Use the Twilio SendGrid Templates API to perform communications operations programmatically. The API provides 11 endpoints covering core functionality including create a transactional template., retrieve paged transactional templates., duplicate a transactional template..

Example prompt: Call POST /v3/templates to create a transactional template.

### Automated Templates Management

Example prompt: Call GET /v3/templates to retrieve paged transactional templates., then verify the result

### AI Agent Integration via Jentic

AI agents discover and call Twilio SendGrid Templates 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 'create a transactional template.', load the operation schema, and execute with Jentic-managed credentials

## Why Jentic

- **Setup:** Wiring the Twilio SendGrid Templates 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 Templates API from the API Directory, store the token once, and your agent calls it.
- **Permission scoping:** The Templates API puts the template id in the URL path (/v3/templates/{template_id}/...), so a rule can pin your agent to one template. You choose the operations it may call, so destructive ones like deleting a template are not included unless you add them.
- **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 'create a transactional template', and Jentic returns the matching Templates operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

### What are the rate limits for the Twilio SendGrid Templates 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 create a transactional template. through Jentic?

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

Yes. Because you run Jentic One yourself, your own rules decide which Templates API operations and credentials the agent may use. You pick the exact endpoints it can call, so read operations like GET /v3/templates stay available while destructive ones such as DELETE /v3/templates/{template_id} are excluded unless you add them. Since the template id sits in the URL path, a rule can also pin the agent to a single template so it cannot touch the others.
