API Request Failed – Nonce Verification Error
Error Message:
There was an error(s) with your Workflow.
API request failed: { “code”:”SRFM_NONCE_VERIFICATION_FAILED”,”message”:”Nonce verification failed.”,”data”:null }

What This Means:
This error occurs when the security token (called a nonce) used during the form submission process has expired or is no longer valid. This is intentional and is a standard security feature in WordPress to ensure each request is unique and protected from misuse.
How to Fix:
To resolve this error, follow these steps to reset the nonce:
- Re-initialize the SureForms and OttoKit: Go back to your workflow and reconfigure the SureForms OttoKit step. This refreshes the nonce and prepares the workflow to accept new data securely.
- Resubmit the Form: Once the trigger is re-initialized, submit the form again. This will generate a fresh nonce.
- Proceed to configure the SureForms Action: Now you can continue to set up your SureForms Action as usual, and the error should no longer appear.
