Passing User Information via URL Parameters

Drimify experiences now support pre-filling user information directly through the URL using query string parameters. This allows for a more personalised experience and streamlines data collection.

✅ Supported URL Parameters

You can pass the following optional variables in the URL:

Parameter	Description	Example Value
`fname`	First name	John or base64 encoded (`Sm9obg==`)
`lname`	Last name	Last name or base64 encoded (`RG9l`)
`email`	Email address	Plain or base64 encoded (`am9obi5kb2VAZXhhbXBsZS5jb20=`)

🔗 Example URLs

Base64 encoded values:

https://apps.drimify.com/your-experience-id/?session_uid=ABC123&fname=Sm9obg==&lname=RG9l&email=am9obi5kb2VAZXhhbXBsZS5jb20=

Plain text values:

https://apps.drimify.com/your-experience-id/?session_uid=ABC123&fname=John&lname=Doe&email=john.doe@example.com

🔒 Encoding & Decoding Logic

You may pass the values either as plain text or as Base64-encoded strings.
Drimify will automatically detect Base64-encoded values and decode them.
Whether Base64-encoded or plain, all values are also raw URL decoded on our side to ensure special characters like spaces (%20), @, or = are properly interpreted.

⚠️ Important for Integrators

Please ensure:

If you send plain text, it must be URL-encoded before being added to the URL.
If you send Base64, you must:

First URL-encode the original value (e.g., John Doe → John%20Doe)
Then Base64 encode that result (John%20Doe → Sm9obiUyMERvZQ==)
Pass it in the query string

Why?

This ensures special characters are preserved correctly and decoded properly in all cases.

✉️ Email Validation

For security and data integrity:

The email parameter will only be used if it passes standard email format validation.
If the value does not match a valid format, it will be skipped and not stored.

💡 Use Cases

Just like we support session_uid to identify a user session, we now support fname, lname, and email to pre-fill user data and avoid displaying a data collection form.
This is ideal when launching experiences from email campaigns or CRM tools, where the participant's information is already known.
Track individual user sessions with less friction
Provide a seamless, personalised user experience
