# Sendblue API

Sendblue iMessage, SMS and RCS messaging API. The API exposes 29 endpoints secured with apiKey authentication.

## For AI agents

Programmatically send message, send group message. Covers 29 operations with apiKey authentication.

## Scope

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

## Capabilities

- Send message
- Create group
- Get message status
- Evaluate service
- List messages

## Use cases

### Communications Operations

Use the Sendblue API to perform communications operations programmatically. The API provides 29 endpoints covering core functionality including send message, send group message, send carousel.

Example prompt: Call POST /api/send-message to send message

### Automated Account Management

Automate account operations by combining multiple Sendblue API endpoints. Agents can send group message and then send carousel in a single workflow.

Example prompt: Call POST /api/send-group-message to send group message, then verify the result

### AI Agent Integration via Jentic

AI agents discover and call Sendblue 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 apiKey tokens manually.

Example prompt: Search Jentic for 'send message', load the operation schema, and execute with Jentic-managed credentials

## Why Jentic

- **Setup:** Wiring the Sendblue API by hand means learning its sb-api-key-id header auth, calling api.sendblue.com, and tracking message and group state yourself. Through Jentic you install once, import the Sendblue API from the API Directory, store the key once, and your agent calls it.
- **Permission scoping:** Sendblue sends messages and creates groups by request body, so scoping stays operations-only: limit the agent to the operations it needs, such as sending a message or reading message status. You choose the operations it may call, so anything you do not add stays out of reach.
- **Credential handling:** Your Sendblue 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 'send a message' or 'check message status', and Jentic returns the matching Sendblue API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

## FAQ

### What authentication does the Sendblue API use?

The Sendblue API uses an API key passed in the `sb-api-key-id` 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 send message with the Sendblue API?

Yes. Use the POST /api/send-message endpoint. The API returns structured JSON responses that agents can parse and act on directly.

### What are the rate limits for the Sendblue 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 send message through Jentic?

Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'send message'. Jentic returns the matching Sendblue API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.

### How many endpoints does the Sendblue API have?

The Sendblue API exposes 29 endpoints covering account, accounts, contacts operations.

### Can I limit what my agent is allowed to do with the Sendblue API?

Yes. Because you run Jentic One yourself, your own rules decide which Sendblue API operations and credentials the agent may use. Since Sendblue scopes access at the operation level, you can add only the endpoints the agent needs, such as sending a message or checking message status, while leaving out operations like creating a group or sending a group message. Anything you do not add stays out of the agent's reach.
