Stripe integration error

Hi there,

I’m trying to integrate Event Espresso with Stripe.

Stripe is in test mode and the yellow test mode flash comes up on the payment screen.

When I put one of the test credit card numbers into the payment box I get the following error:

You did not set a valid publishable key. Call Stripe.setPublishableKey(). For more info see

I’ve tried this in normal mode and in debug mode, but I get the same error.

Can you help?

Hi Daniel,

You’ll need to connect your site to Stripe before you can use the integration. This guide outlines the steps to make that connection:

Hi Josh,

I thought I *had* connected the site to Stripe. (I did follow this guide)

Does this error suggest that the connection wasn’t complete?

I must admit that I got as far as putting in my username and password, which were accepted by Stripe.

Then I finally clicked the blue button, but the window went blank and stayed blank.

Assuming that this is the reason for the lack of connection, how do I finish the connection to Stripe, given the blank white window?

You don’t need to assume in this case, you can go to Event Espresso > Payment Methods and look at the Stripe settings. If the site is connected, you’ll see a checkmark next to the word “Connected”, along with a button to disconnect.

A blank white window could be caused by a number of things. The first thing to try would be do the connection using another web browser.

Hi Josh,

I got as far as receiving a message saying that I had successfully authenticated.

I then clicked the final button to complete the process and got the following error:

Any advice or suggestions?

Thank you

The error at the bottom of your screenshot shows http error 414, which means the URL string was too long for the server to interpret. See also:

If you have a security plugin that’s actively blocking/filtering long URIs you could unset the option that enables that feature. Otherwise you can contact your host and ask then to raise the limit. Under Apache, the limit is a configurable value, LimitRequestLine. If they can change this value to something larger than its default of 8190 it can support a longer request URI.

Hi Daniel,

HTTP Error 414 is ‘The request URL is too long’, you’ll need to contact your host and have them fix this on your server.
