# Sendgrid Twilio SendGrid IP Warmup API

The Twilio SendGrid IP Warm Up API allows you to gradually increasing the volume of mail sent with a dedicated IP address according to a predetermined schedule. This gradual process helps to establish a reputation with ISPs (Internet Service Providers) as a legitimate email sender. SendGrid can automatically warm up dedicated IP addresses by limiting the amount of mail that can be sent through the. The API exposes 4 endpoints secured with bearer authentication.

## For AI agents

Programmatically start warming up an ip address, retrieve all ips currently in warmup. Covers 4 operations with bearer authentication.

## Scope

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

## Capabilities

- Start warming up an IP address
- Retrieve all IPs currently in warmup
- Stop warming up an IP address
- Query and filter Twilio SendGrid IP Warmup API records by parameters
- Monitor Twilio SendGrid IP Warmup API operational status and events

## Use cases

### Communications Operations

Use the Twilio SendGrid IP Warmup API to perform communications operations programmatically. The API provides 4 endpoints covering core functionality including start warming up an ip address, retrieve all ips currently in warmup, retrieve the warmup status for a specific ip address.

Example prompt: Call POST /v3/ips/warmup to start warming up an ip address

### Automated IP Warmup Management

Automate ip warmup operations by combining multiple Twilio SendGrid IP Warmup API endpoints. Agents can retrieve all ips currently in warmup and then retrieve the warmup status for a specific ip address in a single workflow.

Example prompt: Call GET /v3/ips/warmup to retrieve all ips currently in warmup, then verify the result

### AI Agent Integration via Jentic

AI agents discover and call Twilio SendGrid IP Warmup 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 'start warming up an ip address', load the operation schema, and execute with Jentic-managed credentials

## Key endpoints

| Method | Path | Description |
| --- | --- | --- |
| POST | /v3/ips/warmup | Start warming up an IP address |
| GET | /v3/ips/warmup | Retrieve all IPs currently in warmup |
| GET | /v3/ips/warmup/{ip_address} | Retrieve the warmup status for a specific IP address |
| DELETE | /v3/ips/warmup/{ip_address} | Stop warming up an IP address |

## Why Jentic

- **Setup:** Wiring the Twilio SendGrid IP Warmup API by hand means learning its bearer auth where the API key is the token, choosing the right US or EU host (api.sendgrid.com or api.eu.sendgrid.com), and tracking warmup state per IP yourself. Through Jentic you install once, import the Twilio SendGrid IP Warmup API from the API Directory, store the key once, and your agent calls it.
- **Permission scoping:** This API puts the IP address in the URL path (/v3/ips/warmup/{ip_address}), so a rule can pin your agent to reading the warmup status of one IP. You choose the operations it may call, so removing an IP from warmup is not included unless you add it.
- **Credential handling:** Your Twilio SendGrid IP Warmup 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 'start warming up an IP address' or 'check warmup status', and Jentic returns the matching Twilio SendGrid IP Warmup 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 IP Warmup API use?

The Twilio SendGrid IP Warmup 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 start warming up an ip address with the Twilio SendGrid IP Warmup API?

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

### What are the rate limits for the Twilio SendGrid IP Warmup 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 start warming up an ip address through Jentic?

Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'start warming up an ip address'. Jentic returns the matching Twilio SendGrid IP Warmup API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.

### How many endpoints does the Twilio SendGrid IP Warmup API have?

The Twilio SendGrid IP Warmup API exposes 4 endpoints covering ip warmup operations.

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

Yes. Because you run Jentic One yourself, your own rules decide which of the four operations the agent may call and which credentials it may use. Since the IP address sits in the URL path (/v3/ips/warmup/{ip_address}), you can pin the agent to reading the warmup status of a single IP with GET, while leaving out starting warmup with POST or removing an IP with DELETE unless you explicitly allow them. The agent only ever gets the operations you grant.
