# Sendgrid Twilio SendGrid Marketing Campaigns Senders API

The Twilio SendGrid Marketing Campaigns Senders API allows you to create a verified sender from which your marketing emails will be sent. To ensure our customers maintain the best possible sender reputations and to uphold legitimate sending behavior, we require customers to verify their Senders. A Sender represents your “From” email address-the address your recipients will see as the sender of you. The API exposes 6 endpoints secured with bearer authentication.

## For AI agents

Programmatically create a sender, get a list of all senders. Covers 6 operations with bearer authentication.

## Scope

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

## Capabilities

- Create a Sender
- Get a list of all Senders
- Update a Sender

### AI Agent Integration via Jentic

AI agents discover and call Twilio SendGrid Marketing Campaigns Senders 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 sender', load the operation schema, and execute with Jentic-managed credentials

## Why Jentic

- **Setup:** Wiring the Twilio SendGrid Marketing Campaigns Senders API by hand means learning its bearer API key auth, pointing at the api.sendgrid.com host, and handling retries yourself. Through Jentic you install once, import the Marketing Senders API from the API Directory, store the API key once, and your agent calls it.
- **Permission scoping:** This API puts the sender id in the URL path (/v3/marketing/senders/{id}), so a rule can pin your agent to one sender: it can read and resend verification for that sender and nothing else. You choose the operations it may call, so deleting a sender with DELETE /v3/marketing/senders/{id} is not included unless you add it.
- **Credential handling:** Your Twilio SendGrid 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 'create a sender' or 'resend sender verification', and Jentic returns the matching Twilio SendGrid Marketing Senders 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 Marketing Campaigns Senders API use?

The Twilio SendGrid Marketing Campaigns Senders 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 create a sender with the Twilio SendGrid Marketing Campaigns Senders API?

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

### What are the rate limits for the Twilio SendGrid Marketing Campaigns Senders 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 sender through Jentic?

Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'create a sender'. Jentic returns the matching Twilio SendGrid Marketing Campaigns Senders API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.

### How many endpoints does the Twilio SendGrid Marketing Campaigns Senders API have?

The Twilio SendGrid Marketing Campaigns Senders API exposes 6 endpoints covering senders operations.

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

Yes. Because Jentic One is self-hosted, your own rules decide which operations and credentials the agent may use. Since the sender id lives in the URL path at /v3/marketing/senders/{id}, you can pin the agent to a single sender and allow only reading it and resending its verification, while leaving create, update, and delete out of scope. Deleting a sender with DELETE /v3/marketing/senders/{id} is available only if you explicitly add it to what the agent may call.
