Perform Batch Processing of Email verifications with Icypeas
Configured with Google Sheets, HTTP Request. Review the connections and setup before adapting this template.
Node categories in this workflow
- Trigger
- Code
- Data store
- Web / API
Icons describe general node roles, inferred from node types. Inspect the parameters for the configured action.
Drag to pan; use + and − to zoom. Reconstructed from the exported node positions; nothing runs here. Dashed lines represent non-main connections. Full node names and notes appear below.
How it works
The exported workflow contains the following configured nodes. Their connections are shown above; inspect the JSON for the complete logic, expressions, and external actions.
| Node | Category | Type | Operation |
|---|---|---|---|
| When clicking "Execute Workflow" | Trigger | Manual Trigger | See node parameters |
| Authenticates to your Icypeas account | Code | Code | See node parameters |
| Reads lastname,firstname and company from your sheet | Data store | Google Sheets | See node parameters |
| Run bulk search (email-verif) | Web / API | HTTP Request | POST |
Setup
- Download the JSON and import it into an isolated n8n instance. Leave the workflow inactive.
- Connect your own credentials through n8n’s credential store. Replace
REPLACE_WITH_*values with your resource identifiers. - Inspect API destinations, Code nodes, database queries, file paths, and outbound actions.
- Run with synthetic data and harmless destinations. Enable triggers only after checking the actual outputs.
Requirements
An n8n instance with the listed node types and compatible versions. Service-connected workflows may require accounts, credentials, or paid APIs.
Credential types declared in the source
None declared. HTTP requests and Code nodes may still need configuration.

This workflow demonstrates how to perform email verifications (bulk search) using Icypeas. Visit https://icypeas.com to create your account.
Read your Google sheet file
Read your Google sheet file
This node reads a Google Sheet. You need to create a sheet with :
The first column : Header : email
Don't forget to specify the path of your file in the node and your credentials.
Authenticates to your Icypeas account
Authenticates to your Icypeas account
This code node utilizes your API key, API secret, and User ID to establish a connection with your Icypeas account.
Open this node and insert your API Key, API secret, and User ID within the quotation marks. You can locate these credentials on your Icypeas profile at https://app.icypeas.com/bo/profile. Here is the extract of what you have to change :
const API_KEY = "PUT_API_KEY_HERE"; const API_SECRET = "PUT_API_SECRET_HERE"; const USER_ID = "PUT_USER_ID_HERE";
Do not change any other line of the code.
If you are a self-hosted user, follow these steps to activate the crypto module :
1.Access your n8n instance: Log in to your n8n instance using your web browser by navigating to the URL of your instance, for example: http://your-n8n-instance.com.
2.Go to Settings: In the top-right corner, click on your username, then select "Settings."
3.Select General Settings: In the left menu, click on "General."
4.Enable the Crypto module: Scroll down to the "Additional Node Packages" section. You will see an option called "crypto" with a checkbox next to it. Check this box to enable the Crypto module.
5.Save the changes: At the bottom of the page, click "Save" to apply the changes.
Once you've followed these steps, the Crypto module should be activated for your self-hosted n8n instance. Make sure to save your changes and optionally restart your n8n instance for the changes to take effect.
Performs email verifications (bulk).
Performs email verifications (bulk).
This node executes an HTTP request (POST) to verify the emails.
You need to create credentials in the HTTP Request node :
➔ In the Credential for Header Auth, click on - Create new Credential -. ➔ In the Name section, write “Authorization” ➔ In the Value section, select expression (located just above the field on the right when you hover on top of it) and write {{ $json.api.key + ':' + $json.api.signature }} . ➔ Then click on “Save” to save the changes.
To retrieve the results :
After some time, the results, which are downloadable, will be available in the Icypeas application in this section : https://app.icypeas.com/bo/bulksearch?task=email-verification, and you will receive the verification results via email from user@example.com, providing you with the results of your email verifications.
