Fixing Stripe API Errors in Forminator: How the Forminator Stripe App Solves Connection Issues
Category:Wordpress
If your Stripe payments are failing or Forminator is showing API connection errors, the issue is usually caused by missing or invalid Stripe permissions. This happens when Stripe API keys are not properly linked or have been restricted by Stripe for security reasons. To ensure a stable and secure payment connection, the official Forminator Stripe App must be installed on the Stripe account. This app automatically generates and synchronizes the correct API keys and webhooks, eliminating most connection and payment errors. Installing it ensures your Stripe and Forminator integration works reliably and securely.
Why Forminator–Stripe Connections Fail
- Keys are copied incorrectly
- Old or revoked keys are still saved
- Stripe rotated the keys
- A Stripe account was cloned, restricted, or reset
- Webhook permissions are missing
- Stripe blocks API access for security reasons
What the Forminator Stripe App Does
- Generates API keys automatically
- Assigns correct permissions
- Creates required webhooks
- Keeps keys synchronized
- Prevents Stripe security blocks
- Ensures PCI-compliant access
When Should You Install This App?
You should install this app if:- Stripe shows “invalid API key” in Forminator
- Payments stopped suddenly
- Stripe connection fails after switching to live mode
- Webhooks are not being created
- Forminator shows API or authentication errors
- You recently changed Stripe settings or email
- Stripe was previously connected manually
How to Fix the Stripe–Forminator Connection (Step-by-Step)
Step 1 – Install the Stripe App
Ask the Stripe account owner to install this app:
👉 https://marketplace.stripe.com/apps/forminator-stripe-app
They must be logged into the correct Stripe account when installing.
Step 2 – Authorize the App
Stripe will show a permission screen.
Click Install App and allow access.
This automatically:
- Creates API keys
- Assigns webhooks
- Enables secure access for Forminator
Step 3 – Reconnect Forminator
In WordPress:
Forminator → Settings → Payments → Stripe
Click:
Reconnect Stripe
Or
Refresh Connection
Forminator will now fetch the new keys automatically.
Step 4 – Test a Payment
Submit a test form using Stripe test mode or a small live transaction.
You should no longer see:
- API errors
- Key errors
- Webhook failures
Why Manual API Keys Are No Longer Reliable
Stripe is increasingly locking down third-party API usage for security and compliance.
When API keys are manually added:
- They may not have webhook permissions
- They may not have correct scopes
- Stripe may flag them as untrusted
- Payments may fail without warning
The Stripe Marketplace app solves this by creating properly authorized, Stripe-approved keys.
Why This Is the “Correct” Way to Connect Forminator
Stripe officially recommends using Marketplace apps instead of raw API keys because:
- They are safer
- They auto-update
- They prevent payment failures
- They ensure PCI compliance
- They avoid account suspensions
Forminator’s app is built specifically for this.
Common Error Messages This Fixes
Fonts are often overlooked performance killers.
This app resolves:
- “No API key provided”
- “Invalid Stripe credentials”
- “Authentication failed”
- “Webhook not found”
- “Payment could not be processed”
- “Stripe connection error”
- “Live key missing”
Final Recommendation for Clients
If Stripe is not connecting or Forminator shows API errors, do not keep re-entering keys.
Instead, install the official Stripe app:
https://marketplace.stripe.com/apps/forminator-stripe-app
It is the fastest, safest, and Stripe-approved solution.
