Stripe Error

FAQ & Troubleshooting · 1 min read · Updated May 21, 2026

A troubleshooting fix for various Stripe-related errors — bad API keys, mismatched test/live mode, declined cards, 3D Secure / SCA flow failures, webhook misconfigurations. This guide walks through the diagnostic flow by symptom.

If you get  {“error”:{“message”:”No application matches the supplied client identifier”}} error while you are trying to process via Stripe Payment Gateway that means you are using Stripe Connect add-on on single site. Stripe Connect add-on can be used only on WP Multiste. Stripe Connect allows you to charge transaction fees/commission for each subsite in your WordPress multisite network.

In case you want to use Stripe payment gateway on your single site, you just have to deactivate Stripe Connect add-on since regular Stripe Payment Gateway is already integrated into Tickera.

Here you can find the instruction on how to set up Stripe Payment Gateway.
