A guide to generating UUIDs with Sendlane

Sendlane offers personalization tags and custom fields which dynamically pull in campaign and contact data. By using combinations of these we can generate and pass unique identifiers (UUIDs) into the "key" parameters without the need for any javascript. For example:

VAR_FIRST_NAME   pulls in the recipient's first name
VAR_LAST_NAME   pulls in the recipient's last name
VAR_CAMPAIGN_ID  pulls in the campaign's unique ID

By combining these tags, we can successfully create dynamic UUIDs and our "key" parameter values would therefore look something like this:

<a href="
<img src="

NOTE: the same tags should be passed into the "key" parameter values of both the click and image URLs just like we've done above.
