Install Jentic One Beta

Connect the Twilio SendGrid Legacy Marketing Campaigns Campaigns API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Twilio SendGrid Legacy Marketing Campaigns Campaigns API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fsendgrid.com%2Ftwilio-sendgrid-legacy-marketing-campaigns-campaig" | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fsendgrid.com%2Ftwilio-sendgrid-legacy-marketing-campaigns-campaig" | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Why Jentic?

What agents get from Jentic-routed access to this vendor.

Setup

Wiring the Twilio SendGrid Legacy Marketing Campaigns Campaigns API by hand means learning its bearer API key auth, pointing at the api.sendgrid.com host, and handling paging and retries yourself. Through Jentic you install once, import the Campaigns API from the API Directory, store the API key once, and your agent calls it.

Permission scoping

This API puts the campaign id in the URL path (/v3/campaigns/{campaign_id}), so a rule can pin your agent to one campaign: it can read and schedule that campaign and nothing else. You choose the operations it may call, so deleting a campaign with DELETE /v3/campaigns/{campaign_id} is not included unless you add it.

Credential isolation

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.

Intent-based discovery

Agents search Jentic by intent such as 'create a campaign' or 'schedule a campaign', and Jentic returns the matching Twilio SendGrid Campaigns API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Twilio SendGrid Legacy Marketing Campaigns Campaigns API through Jentic.

What authentication does the Twilio SendGrid Legacy Marketing Campaigns Campaigns API use?

The Twilio SendGrid Legacy Marketing Campaigns Campaigns 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 campaign with the Twilio SendGrid Legacy Marketing Campaigns Campaigns API?

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

What are the rate limits for the Twilio SendGrid Legacy Marketing Campaigns Campaigns 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 campaign through Jentic?

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

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

The Twilio SendGrid Legacy Marketing Campaigns Campaigns API exposes 11 endpoints covering campaigns API operations.

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

Yes. Because you run Jentic One yourself, your own rules decide which SendGrid operations the agent may call and which credentials it may use. Since this API puts the campaign id in the URL path (/v3/campaigns/{campaign_id}), you can pin the agent to a single campaign so it only reads and schedules that campaign and nothing else. You choose the allowed operations, so a destructive call like DELETE /v3/campaigns/{campaign_id} is excluded unless you explicitly add it.
