I tried testing for this and it looks like I need to install the add on. Currently can’t log in on either Android or IOS. Where might I find this?

Hi Jaclyn,

It turns out the Android and iOS apps that work with the Event Espresso 3 JSON API plugin are not compatible with the JSON API for Event Espresso 4.

You can learn about the JSON API for Event Espresso 4 here:

If you want to scan tickets for Event Espresso 4, I can recommend using the barcode scanning add-on. There’s more information about the scanning add-on here:

There’s also some documentation that you can follow about how to use a mobile device to scan Event Espresso 4 tickets here:

Dear Josh,

Just bought a full license for Event Espresso 2 days ago.

I am also trying to use the IOS “Event Espresso” to do the scanning but keep getting “Sorry, can’t log in – 404-not found”.

I have tried installing JSON API and when I see this reply, I install the new API as recommended but still cannot solve that problem

Since I am still testing, I did not install the key yet. I don’t think it make a difference right?

Plugin Installed:
Event Espresso: Version 4.8.19.p
Event Espresso – Barcode Scanner (EE 4.6.0+)
Event Espresso – Events Table View Template (EE 4.4.9+)
Event Espresso – REST API (EE4.6.32+)
Event Espresso – Ticketing (EE4+)

To add-on, I cannot use a “barcode scanning add-on” with barcode scanner as my customer will all come in using their mobile phone to redeem.

I tried and scanner cannot read from a mobile screen.

Hi Lawrence,

Currently the JSON API for EE4 does not work with the mobile apps that were built for Event Espresso 3. It turns out there are scanners that are built to read off mobile screens, and there are also mobile apps that use the built in camera on your mobile device that can be used. You can follow this guide for more information about mobile device scanning:
