How to Add a Signature in HubSpot Forms
7/8/2025
HubSpot is a powerful tool for managing your customer relationships. However, it does have its limitations. One such limitation is the lack of a native signature field in HubSpot forms. But, you don’t have to worry; there are several ways to incorporate signature functionality into your HubSpot forms. Here’s a straightforward guide to help you explore your options.
1. Integrate with E-Signature Platforms
Integrating third-party e-signature services with HubSpot is one of the most effective ways to manage signatures. Some popular e-signature services you can use include:
- DocuSign Integration: Connecting DocuSign to HubSpot allows you to automate signature requests. When someone submits your HubSpot form, DocuSign instantly generates a signature request. This way, documents can be sent out for signature immediately after the form is filled out. You can find more details on how to set this up through Zapier.
- PandaDoc Integration: Similar to DocuSign, PandaDoc can also be integrated with HubSpot. This integration lets you create and send documents for signature based on form submissions. You set it up in much the same manner as DocuSign.
By utilizing these integrations, you streamline the process of collecting signatures. Plus, they keep all your documents organized.
2. Redirect to an E-Signature Platform Post-Submission
Another method involves redirecting users to an e-signature platform after they submit a HubSpot form. Here’s a step-by-step approach:
- Set Up Your HubSpot Form: Create your form as you normally would, including all necessary fields.
- Configure Redirect Settings: After the form is completed, adjust the post-submission action in the form settings to redirect users to your preferred e-signature platform.
This method guides users to the designated e-signature site, making the process clear and straightforward. It is essential to ensure that the experience feels seamless for users.
3. Embed a Signature Field Using Custom HTML and JavaScript
If you have some technical skills, consider embedding a signature field directly into your HubSpot form. This involves a bit more work, but it is doable:
- HTML5 Canvas: You can add an HTML5 canvas element to your form. This allows users to draw their signature using a mouse or touchscreen.
- Data Handling: Use JavaScript to capture the signature drawn on the canvas. You’ll need to convert it into a base64-encoded image string. Store this string in a hidden field in your form. When submitted, this field will be included with your form data.
This method offers a smooth user experience, as users can sign directly on the form. However, it does require some programming knowledge.
4. Use File Upload Fields for Signature Images
A more straightforward but less seamless method is to include a file upload field in your form. Here’s how it works:
- User Action: Users can print and sign a document, scan the signature, and then upload the file through the form.
- Considerations: This method is easy to set up but may be less user-friendly. Users must take multiple steps to provide their signature compared to direct signature options.
While it may not offer the best user experience, it remains an alternative in case other methods are beyond your current capabilities.
Conclusion
In summary, while HubSpot forms do not directly support signature fields, there are viable approaches to incorporate signatures into your processes. You can integrate third-party e-signature platforms like DocuSign and PandaDoc, redirect users to an e-signature site after form submission, embed a signature field with HTML and JavaScript, or allow file uploads with scanned signatures. Choose the method that best fits your technical skill level and user experience goals.
