The Append HTTP setting controls whether the https:// prefix is automatically added to your smart links in SMS messages.
Why does it matter? #
- When enabled (true): Your links will include https:// (e.g., https://example.com). This is the default and recommended setting, as it increases recipient trust and improves click rates.
- When disabled (false): The https:// part is removed (e.g., example.com). This saves about 6–8 characters, which can be useful if you’re close to the SMS character limit.
⚠️ Important: While disabling saves characters, recipients may hesitate to click on links without https://. Always test with a small audience before rolling it out to a full campaign.
API Usage #
If you are sending messages through the API, you can control this behavior using the parameter:
- appendHTTP=true → Adds https:// to your smart link (default).
- appendHTTP=false → Removes https:// from your smart link.
Best Practice #
Keep Append HTTP = true unless you absolutely need to save characters.
