SendGrid is a cloud-based service for delivering transactional and marketing emails. Connecting this integration allows your application to send emails programmatically (e.g., welcome emails, password resets, or notifications).

Configuration Steps

After selecting SendGrid from the integration list, a configuration modal will appear. You must provide the following credentials to establish the connection:

1. API Key

This is the authentication token generated within your SendGrid account.

• Input: Paste your private SendGrid API Key into the text field.
• Help: If you do not have one, click the “Where to find API Key?” link provided in the modal for instructions on how to generate it.

2. Environment

Specify the environment context for this integration.

• Input: Enter the environment identifier (e.g., Production, Staging, or a specific configuration tag) in the Environment field.

Finalizing the Connection

Once the fields are filled:

1. Review the status bar (currently showing Not Connected).
2. Click the black Add button at the bottom right to save the credentials and activate the integration.

    suggestions
  }
}

Response (with SendGrid Premium):

{
  "data": {
    "sendgrid_validateEmail": {
      "valid": true,
      "score": 0.95,
      "local": "test",
      "domain": "example.com",
      "reason": "",
      "suggestions": []
    }
  }
}

Response (Basic validation - when SendGrid Premium is not available):

{
  "data": {
    "sendgrid_validateEmail": {
      "valid": true,
      "score": 0.8,

Note: The SendGrid email validation endpoint (/v3/validations/email) requires special permissions and may not be available in all accounts. If your API key does not have access to this endpoint (error 403), the system will automatically use basic validation based on regex as a fallback.
