Enrich Company Data Using the SIREN Number

Explainer video

In this tutorial, Sandro, cofounder of Gemeos Webflow agency, shows you how to enrich company data based on a SIREN number

1. Build your page structure in Webflow

Make sure to add a "Text Field" so you can enter a SIREN number. I recommend collecting all the info in a form so you can easily send it to your CRM or another DB when the prospect submits their details.

Of course, you can — and I recommend this — set some fields to “display: none” so prospects don’t see them. Especially the enriched fields.

2. Add “custom attributes” to the elements you want to use in Wized

Make sure to use “wized” as the Name, and feel free to choose whatever Value you want.

For example, I used:

• sireninput
• accountname
• naf
• address

3. Connect your Webflow account to Wized

Go to Wized and create a new project. Add your Webflow site URL (the “webflow.io” link), then add the custom code to your project footer.

4. Connect to the SIREN API

1. Go to “App”
2. Create a new app
3. Give it a name and select Rest API as the app type
4. Enter the base URL: “https://data.siren-api.fr/”

5. Fetch the data

1. Go to “Data in”
2. Select the app you just created
3. Enter the endpoint URL (/v3/unites_legales/) and add the input field for the SIREN number as a variable

1. Add your API key as a URL parameter

6. Create the action that retrieves the SIREN data

1. Go to Action
2. Select the attribute of your SIREN input field in “Apply to”
3. Select “On change” in the “Configuration” tab settings and “Perform request” for the Action, then choose the Data in request you configured just before

7. Enrich your form fields based on the SIREN number entered

1. Go to Action
2. Select the attribute of the input field you want to fill in
3. Select “Set input value” in the “Configuration” tab settings, then choose the value you want from the results
4. Repeat the same process for the other fields you want to enrich

8. Conclusion

As you can see, it’s pretty simple to enrich company data based on a SIREN number with the SIREN API + Wized

Useful real-world use cases?

• Score your prospects based on different criteria like the NAF code, business area, company founding year, and adjust your sales pressure accordingly
• Increase the conversion rate of your qualification forms (one field lets you enrich a whole set of data)
