     ```bash frame="terminal"
       pip install scalekit
       ```
     Full SDK reference: [Node.js](/agentkit/sdks/node/) | [Python](/agentkit/sdks/python/)

   <AgentKitCredentials />

3. ### Set up the connector

   Register your SendGrid credentials with Scalekit so it can authenticate requests on your behalf. You do this once per environment.

4. ### Make your first call

   <QuickstartGenericApikeySection connector="sendgrid" toolName="sendgrid_get_integrations_by_user" providerName="SendGrid" />

## What you can do

Connect this agent connector to let your agent:

- **Ip warm up, add sub users to** — Put a SendGrid IP address into warmup mode
- **Token verify sender** — Verify a pending Sender Identity using the verification token SendGrid generated and included in the verification email sent to the address pending verification
- **Dns validate reverse, set up reverse** — Validate a Reverse DNS record by its id, checking whether the required A record has been correctly set up at your DNS host
- **Email validate** — Validate a single email address using SendGrid's Email Address Validation service
- **Link validate branded** — Validate a branded link (link branding / click-tracking domain) by ID: SendGrid re-checks the DNS records (domain_cname and owner_cname) required for that branded link and reports whether it is now valid
- **Domain validate authenticated, disassociate subuser from, authenticate** — Validate a domain authentication by ID: SendGrid re-checks the DNS records (CNAME/SPF/DKIM, depending on the domain's setup) required for that authenticated domain and reports whether it is now valid
