Prerequisites

Before creating a SendGrid credential, you need to obtain your API key from your SendGrid account. SendGrid uses API key authentication for all API requests, with the API key sent in the Authorization header with the Bearer prefix.

To obtain your SendGrid API key, follow these steps:

1. Sign in to your SendGrid account using your administrator credentials.

2. Navigate to your account settings or API management section in the SendGrid interface.

3. Look for the API Keys or API section in your account settings, or navigate to Settings > API Keys or Account > API Keys.

4. If you don't have an API key yet, look for the option to generate or create your API key.

5. Click Create API Key or Generate API Key to create a new API key.

6. Configure your API key settings:

   • Enter a name for the API key (e.g., "Nexla Integration")
   • Select the API key permissions (Full Access, Restricted Access, or Billing Access)
   • Review and select the specific permissions or scopes for the key (if using Restricted Access)

7. Click Create & View or Create to create the API key.

8. Copy the API key immediately after it's generated, as it may not be accessible again after you navigate away from the page.

9. Store the API key securely, as you will need it to configure your Nexla credential. The API key is sensitive information and should be kept confidential.

The API key is sent in the Authorization: Bearer {key} header for all API requests to the SendGrid API. The API key authenticates your requests and grants access to SendGrid resources based on your account permissions. If your API key is compromised, you should immediately revoke it in your SendGrid account settings and generate a new one. For detailed information about obtaining API keys, API authentication, and available endpoints, refer to the SendGrid API documentation.

Sample data will be displayed in the Endpoint Test Result panel on the right, allowing you to verify that the source is configured correctly before saving.

Manual configuration

SendGrid data sources can also be manually configured to ingest data from any valid SendGrid API endpoint, including endpoints not covered by the pre-built templates, chained API calls, or custom query parameters. Select the Advanced tab at the top of the configuration screen, and follow the instructions in Connect to Any API to configure the API method, endpoint URL, date/time and lookup macros, path to data, metadata, and request headers.

The SendGrid API typically uses the GET method for retrieving data. The API endpoint URL should include the API version (/v3/) and the resource type path, for example https://api.sendgrid.com/v3/user/profile or https://api.sendgrid.com/v3/stats.

For the Response Data Path, use $ to extract the entire response for single record endpoints, $[*] to extract all items from the response array, or $.result[*] to extract all items from the result array, depending on your endpoint. For pagination, SendGrid uses next token-based pagination on some endpoints, with the token parameter name page_token and the JSONPath expression to the next page token at $._metadata.next.

Once all of the relevant settings have been configured, click the Create button in the upper right corner of the screen to save and create the new SendGrid data source. Nexla will now begin ingesting data from the configured endpoint and will organize any data that it finds into one or more Nexsets.

Use as a destination

Click the + icon on the Nexset that will be sent to the SendGrid destination, and select the Send to Destination option from the menu. Select the SendGrid connector from the list of available destination connectors, then select the credential that will be used to connect to your SendGrid account, and click Next; or, create a new SendGrid credential for use in this flow.

Endpoint templates

Nexla provides pre-built templates that can be used to rapidly configure destinations to send data to common SendGrid endpoints. Select the endpoint to which data will be sent from the Endpoint pulldown menu. Then, click on the template in the list below to expand it, and follow the instructions to configure additional endpoint settings.

Mail Send

This endpoint template allows you to send email over the SendGrid v3 Web API using records from a Nexset. Use this template when you need to send transactional or marketing emails through SendGrid. Check out the API documentation link for required record schema.

• This endpoint sends data as JSON in the request body to send emails through your SendGrid account. Each record from your Nexset will be sent as a separate API request to send an email. The request body should contain the email data in the format required by the SendGrid API.

This endpoint sends data as JSON in the request body to send emails through your SendGrid account. Each record from your Nexset will be sent as a separate API request to send an email. The request body should contain the email data in the format required by the SendGrid API, including recipient information, subject, content, and other email properties.

The email structure must match the SendGrid API's expected format. For detailed information about email sending, request body formats, required record schema, and available email properties, see the SendGrid API documentation.

Manual configuration

SendGrid destinations can also be manually configured to send data to any valid SendGrid API endpoint. Using manual configuration, you can also configure Nexla to automatically send the response received from the SendGrid API after each call to a new Nexla webhook data source. Select the Advanced tab at the top of the configuration screen, and follow the instructions in Connect to Any API to configure the API method, data format, endpoint URL, request headers, attribute exclusions, record batching, and response webhooks.

The SendGrid API typically uses the POST method for creating resources and sending emails, and expects JSON format for all requests. The API endpoint URL should include the API version (/v3/) and the resource type path, for example https://api.sendgrid.com/v3/mail/send.

The request body should contain the resource data formatted as JSON, with field names matching the SendGrid API's expected structure. The request body format is typically {message.json} to send the entire Nexset data as JSON, or you can construct a custom JSON structure with specific field mappings. SendGrid API uses specific structures for different endpoints (mail send, contacts, etc.). For detailed information about request body formats, available endpoints, and resource structures, see the SendGrid API documentation.

Save & activate

Once all endpoint settings have been configured, click the Done button in the upper right corner of the screen to save and create the destination. To send the data to the configured SendGrid endpoint, open the destination resource menu, and select Activate.

The Nexset data will not be sent to the SendGrid endpoint until the destination is activated. Destinations can be activated immediately or at a later time, providing full control over data movement.
