Sending vCard via Twilio Integration with MMS: Issue and Workaround


Customer.io

 

Introduction

 

In this post, we will address an issue users encounter when trying to send a vCard file via Twilio integration with MMS due to unsupported file type. And, of course, we will present a couple of helpful workarounds to keep you going.

 

Problem

The issue here is the inability to send vCard files through Twilio's MMS platform because the file type is unsupported. This can pose a significant obstacle if your project or workflow heavily depends on sending such files. For MMS sent via our Twilio integration, the supported file types are .jpeg, .png, and .gif, with a recommended max size of 600KB. “Real” max size varies up to 1.5 MB based on telephone carriers. Unfortunately, vcard is not a supported format at the moment.

Solution

Good news! We have two potential workarounds for this. First, you may consider hosting the vCard file on a different platform and simply include the link to that file in your SMS or MMS. This approach enables the recipient to download the vCard file from the link directly.

Alternatively, another workaround suggests the use of a webhook for effectively dealing with unsupported file types.
