Locate your Credentials for PayPal Express

1) Login to your account.

5) Click Request API Credentials.
6) Click Request API signature.

You can then copy and paste the API username, password, and signature into the payment methods page for Event Espresso within your WP dashboard and then click on the Update Settings button.

An account with PayPal is needed to accept payments via PayPal Express and an SSL certificate is recommended for securing your website.


I configured PayPal Express and payments are not being processed. Can you help?
Double-check your credentials to make sure that you are using live credentials which are for production mode. Also, ensure that there is no extra spacing before or after the credentials in the payment methods page of Event Espresso.

When I refund a payment, does it also refund through PayPal Express?
Refunds in Event Espresso 4 are currently a two step process. First, apply the refund through the transactional details screen of Event Espresso in your WP-admin (WP dashboard). Then login to your PayPal merchant account and process the refund.

I’m seeing a security header not valid error. What does this mean?
There is a problem with your credentials. Double-check that they are for a production/live account and if needed deactivate the existing credentials and create a new set. Then update these in the payment methods page of Event Espresso within your WP-admin (WP dashboard).

How can I setup a recurring payment or subscription through PayPal Express?
Recurring or subscription payments are not currently supported in the PayPal Express payment gateway.

Is an SSL certificate needed for PayPal Express?
A dedicated SSL certificate is recommended if you are accepting payments on your website.
